• The text has been updated to a more clear and concise version with the latest research literature and a revised list of chapters.

• New Illustrative Biographies: Sonia Sotomayor (Chapter 8) and Barack Obama (Chapter 13).

• Clearer presentation of some issues (e.g., recovered memory; hypnosis) (Chapter 2), additional references making comparisons with other religious traditions (Chapter 16), and a more concise history of Buddhism (Chapter 16).

• Expanded discussion, in the presentation of Erikson’s biography, of the current state of child analysis. Clearer presentation of identity development and moratorium, and some longitudinal research about identity development. Expanded discussion of cross-cultural research (especially regarding the stage of generativity). Mention of terrorists as examples of a foreclosed identity (Chapter 5).

• Expanded content about research on relational approaches with respect to brain functioning and mental health issues (e.g., border- line personality; narcissism) (Chapter 6) and clearer presentation of psychological types (Chapter 3).

• Updated discussion of religious orientations, including more cross-cultural material (e.g., religious orientation in Muslim populations, and in American ethnic groups) (Chapter 7).

• Expanded discussion of the Big Five, and reduced focus on Cattell’s older theory. Expanded discussion of cross-cultural studies of the Five Factor model. More studies of implications of the five factors for life outcomes (e.g., aging and retirement) (Chapter 8).

• Expanded discussion of behavioral genetics and new table on heritability of specific personality characteristics as well as cultural and cross-cultural issues as contexts (Chapter 9).

• The Behaviorism section has been updated with an abridged version of Dollard and Miller’s theory along with Skinner’s theory (also abridged) and Staats’s theory. The Illustrative Biography of Tiger Woods has been updated, discussing how behavioral approaches are specific to particular behaviors, so that a behavioral interpretation of his success at golf (emphasized in the previous edition) shows the limitations of this approach, which does not present a broader view of personality that would have predicted his marital and infidelity problems, which are discussed in this edition (Chapter 10).

• Mischel and Bandura are each discussed in a separate chapter, instead of being combined into the same chapter (in the previous edition). Expanded discussion of the Wediko Camp study (included in this edition) that was the basis of Mischel’s research on traits and situations. The CAPS model is presented as a distinct section. Discussion of the cultural learning and implications of cognitive affective units in the CAPS model (including race differences in response to the O. J. Simpson verdict, and interpersonal relation- ships in the context of prejudice). Discussion of cross-cultural studies of the CAPS model (the United States and Philippines). Discussion of the importance of measuring situations (Chapter 12).

• Expanded section on Positive Psychology, organized in terms of the “three pillars” of positive psychology, with attention to both the individual and social institutions. Also, a new discussion of why happiness is an important theoretical focus, based on an evolutionary argument (Chapter 15).

PREFACE

Writing this book, with its various editions, has been roughly a two-decade process (so far), and I’ve come to a realization that it will always be a work in process. What used to feel like “completion” now feels simply like a “milestone” as each edition is sent to production. That is fitting, as the field, too, is very much in process. Over the years, some of the hot topics (like the debate over traits versus situationalism, and the controversy over repressed memory of abuse) have faded into the histori- cal past as theories have matured and research has guided reconceptualizations; and some topics have been dropped altogether, in order to make room for the new. The organization of this book has changed a bit to reflect these historical developments. Previously a full chapter, the Dollard and Miller contributions to a behavioral analy- sis of psychoanalytic theory are now part of a consolidated behavioral chapter, with Skinner and Staats. Behaviorism itself has been combined with cognitive behaviorism into one part (Part IV). Positive psychology is growing, and I have expanded its scope within the Maslow chapter, imagining that Abe Maslow would applaud psychology for finally heeding his vision, at least in part.

And while not reflected in the words I have crafted for this edition, I have frequently reminisced about the first term paper I wrote in my first personality course, where I explored all that I could find written by Gordon Allport. If there is a unitary statement, however vague and incomplete, for the field of personality, it seems—at least at this moment, to me—to be his personology. But the details are lacking in his statements, and for that, we need many other theories, ranging from the exciting findings of neuroscience to the very practical and socially important recognition of cultural contexts (e.g., challenges to the Protestant bias of Allport-inspired work on religious orientations). Researchers and theorists in personality have more contributions that deserve reporting than I can possibly report, or even (alas) read! So many things to say, it would take a whole series of books! I invite students to do as I have done, and make understanding personality a life’s work.

One of the major challenges of this edition has been to reduce the total length of the manuscript. Students, both in my classes and in those taught by others who use this book, will undoubtedly be glad for the pruning, but many of those cuts nicked this writer’s Muse as well. How can students of personality not be given more details of this, or of that, I ask myself—but then remember that there is only so much that can be absorbed on a first introduction to the field. All in all, the wisdom of my editors who requested this cutting is hopefully apparent in places that are easier to read. The choice of what to cut was only mine, though, and I apologize if I have made choices with which returning readers disagree. New editions, like nature herself, demand some clearing in order to make room for new growth.

Closer to home, several friends and colleagues have offered advice, loaned books, and given emotional support and encouragement when I needed it. So thank you: Russell Couch, Bronna Romanoff, and others in the Psychology Department at The Sage Colleges, where they have watched me juggle (not always successfully) the demands of a full teaching load, committee work, chairing the IRB, and other faculty responsibilities with “The Book.” Special thanks to Nigel Wright, who not only appeared with a full box of books for me to read for an earlier revision (sorry, Nigel—I could not read them all!), but who also reminded me recently that I really indeed do love writing, at a time when exhaustion and an overdue manuscript led me to claim the opposite. His insatiable love of books inspires me. To my son John, thanks for all you have done by what you say and how you live—and one of these days, the other book that is dedicated to you will (hopefully) be ready.

My editors at Pearson have supported this project marvelously, with plenty of advance planning and organizing reviews—and patience for my delinquencies—and so special thanks to Susan Hartmann, Alexandra Mitton, Shiny Rajesh, and others with whom I have not had so much personal contact. Over the years and editions, they are joining others from Pearson in a larger personification of “My Editor,” who makes me feel sometimes important, sometimes rushed, but always expanded to a larger project than my professorial role. Writing is, if not at every moment fun, at least always a challenge and a privilege.

Introduction to Personality Theory

Writers and philosophers have reflected about personality for centuries. They describe various types of people.

The true artist will let his wife starve, his children go barefoot, his mother drudge for his living at seventy, sooner than work at anything but his art. (George Bernard Shaw, Major Barbara, act 1)

A fool uttereth all his mind. (Prov. 29:11)

They tell us about the dynamic motivations and emotions of human nature.

We would all be idle if we could. (Samuel Johnson, quoted in Boswell’s Life of Johnson)

Unlimited power is apt to corrupt the minds of those who possess it. (William Pitt, speech, House of Lords, January 9, 1770)

Sayings tell us how personality develops down various paths.

Train up a child in the way he should go: and when he is old, he will not depart from it. (Matt. 22:6)

Spare the rod and spoil the child. (Samuel Butler, Hudibras, pt. ii, c. I, 1. 844)

With centuries of such commentary about personality, we might think that we may leave scientific investigation for other problems, perhaps to explore the mysteries of the physical universe and biological processes. Yet formal study is needed, perhaps here more than anywhere, for there are contradictions in culture’s lessons about personality.

Virtue is bold, and goodness never fearful. (Shakespeare, Measure for Measure, act 3, line 215)

Boldness is a child of ignorance and baseness. (Francis Bacon, Essays, line 12)

How can we know, given such contradictory observations, whether boldness should be admired or pitied? Perhaps when we and our friends are bold, we will agree with Shakespeare and leave Bacon’s skepticism aside until we confront a bold enemy. Such sayings, although charming, are disconcerting because there seems to be a saying to support any belief. Cultural sayings do not offer a systematic understanding of human nature. For that, we turn to psychology.

PERSONALITY: THE STUDY OF INDIVIDUALS

Psychology uses the methods of science to come to some clearer and less ambiguous (if, alas, less literary) understandings of human nature.

Definition of Personality

Personality may be defined as the underlying causes within the person of indi- vidual behavior and experience. Personality psychologists do not all agree about what these underlying causes are, as the many theories in this text suggest. They offer a variety of answers to three fundamental questions. First, how can personal- ity be described? Personality description considers the ways in which we should characterize an individual. How do people differ from one another, and should we describe personality traits by comparing people with one another or use some other strategy, such as studying each individual separately? Second, how can we understand personality dynamics—how people think about and adjust to their life situations, and how they are influenced by culture? Third, what can be said about personality development—how personality changes over the life span, influenced by biological factors and experience? These three questions are so fundamental that each theory considers them in some way.

DESCRIPTION OF PERSONALITY

The most fundamental theoretical question is this: What concepts are useful for describ- ing personality? Should we concentrate on the differences between people? Or should we avoid comparisons, instead focusing on intensive understanding of one person?

Differences between People: Groups or Gradations?

Personality researchers have devoted considerable effort to identifying the ways that individuals differ from one another—that is, of describing individual differences. Essentially, we have the choice of classifying people into a limited number of separate groups, a type approach. Or we can decide that people vary in gradations and describe people by saying how much of the basic dimensions they possess, a trait approach.

TYPES The type approach proposes that personality comes in a limited number of distinct categories (qualitative groupings). Such personality types are categories of people with similar characteristics. A small number of types suffice to describe all people. In ancient Greece, for example, Hippocrates described four basic types of temperament: sanguine (optimistic), melancholic (depressed), choleric (irrita- ble), and phlegmatic (apathetic) (Merenda, 1987). Each person belongs to only one category.

TRAITS AND FACTORS Nature often presents us with more gradual transitions (quantitative dimensions). Consider “cruelty”: Between Mother Teresa and Stalin lie many intermediate levels of cruelty. Therefore, personality researchers generally

prefer quantitative measures, which give each person a score, ranging from very low to very high or somewhere in between. In contrast to types, traits are such quantitative measures. They describe a narrower scope of behavior. Traits permit a more precise description of personality than types because each trait refers to a more focused set of characteristics, and each person is a combination of many traits.

More traits than types are necessary to describe a personality. One classic study counted nearly 18,000 traits among words listed in the dictionary (Allport & Odbert, 1936). Do we really need that many? To eliminate unnecessary redundancy (e.g., by combining synonyms such as “shy” and “withdrawn”), researchers rely on statisti- cal procedures that compute correlations among trait scores, and on that basis they have proposed broad factors of personality. Factors are quantitative, like traits, but they include a broader range of behavior. Factors are often thought to derive from underlying biological variables.

Types, traits, and factors all have a role in personality theory and research. The terms are sometimes used imprecisely, but knowing their differences (summarized in Table 1.1) helps us understand the variety of ways that personality can be described and measured.

Comparing People or Studying Individuals: Nomothetic and Idiographic Approaches

Personality traits and types allow us to compare one person with another: the nomothetic approach. Most personality research is nomothetic. Despite its scientific advantages, the nomothetic method has drawbacks. It studies many people and com- pares them on only a few numerical scores, which makes it difficult to understand one whole person (Carlson, 1971). Much personality research is also limited because it often investigates college students (Carlson, 1971; Sears, 1986), who are more con- veniently available to researchers but who differ from the general adult population on many personality characteristics (Ward, 1993).

In contrast, the idiographic approach studies individuals one at a time. Strictly idiographic approaches are difficult because any description of a person (e.g., “Mary is outgoing”) implies comparison with other people. Although implicit comparisons with other people are unavoidable, we call research idiographic if it focuses on the particularities of an individual case, for example, in a case study or a psychobiographical analysis. William McKinley Runyan reminds personality psychologists of Kluckhohn and Murray’s (1953) classic assertion: “Every man is in certain respects (a) like all other men, (b) like some other men, (c) like no other man” (1988, p. 53). Personality psychology can discover truths about unique individuals, as well as typical group characteristics and universal principles.

quantitative measures

measures that permit expression of various amounts of something, such as a trait

personality characteristic that makes one person different from another and/or that describes an individual’s personality

factor

a statistically derived, quantitative dimension of personality that is broader than most traits

nomothetic

involving comparisons with other individuals; research based on groups of people

idiographic

focusing on one individual

Table 1.1 Types, Traits, and Factors: Three Ways of Describing Personality

Types Type membership is an all-or-nothing thing (a qualitative variable). A person belongs to one and only one category. Theoretically, a small number of types describe everyone. A person fits into only one type.

Traits Trait scores are continuous (quantitative) variables. A person is given a numeric score to indicate how much of a trait the person possesses. Theoretically, there are a great many traits to describe everyone. A person can be described on every trait.

Factors Factor scores are also continuous (quantitative) variables. A person is given a numeric score to indicate how much of a factor the person possesses. Theoretically, a small number of factors describe everyone. A person can be described on every factor.

PERSONALITY DYNAMICS

The term personality dynamics refers to the mechanisms by which personality is expressed, often focusing on the motivations that direct behavior. Motivation provides energy and direction to behavior. If you see a person running energetically toward a door, you may ask, “Why is that person running?” What is the motivation? Theorists discuss many motives. Some theorists assume that the fundamental motivations or goals of all people are similar. Sigmund Freud suggested that sexual motivation underlies personality; Carl Rogers proposed a tendency to move toward higher levels of develop- ment. Other theorists suggest that motives or goals vary from one person to another. For example, Henry Murray (1938) listed dozens of motives that are of varying importance to different people, including achievement motivation, power motivation, and nurturance.

Personality dynamics include individuals’ adaptation or adjustment to the demands of life and so have implications for psychological health. Modern personal- ity theory considers cognitive processes as a major aspect of personality dynamics. How we think is an important determinant of our choices and adaptation. In addition, culture influences us through its opportunities and expectations.

Adaptation and Adjustment

Personality encompasses an individual’s way of coping with the world, of adjusting to demands and opportunities in the environment—that is, adaptation. Many theories of personality have historical roots in the clinical treatment of patients. Observations of their symptoms, and of increasing adjustment with treatment, suggested more general ideas about personality that have been applied broadly to nonclinical populations; conversely, studies of nonclinical populations have implications for therapy.

Cognitive Processes

What role does thinking play? Theories vary considerably on this question. Based on clinical experience, Sigmund Freud proposed that conscious thought plays only a limited role in personality dynamics; unconscious dynamics are more important in his psychoanalytic theory. Other approaches disagree, emphasizing conscious experi- ence and investigating various thought patterns that predict behavior and coping. The ways that we label experience and the ideas we have about ourselves have substantial effects on our personality dynamics.

Culture

Historically, personality theories focused on the individual, leaving culture and soci- ety in the background. This left an incomplete picture of personality and prevented theories from adequately explaining gender, ethnic, and cultural differences. Influenced by greater awareness of cultural change, researchers have increasingly considered the role of culture in personality. Individualistic cultures, like the United States, emphasize individual differences in personality traits more than do collectivist cultures (Heine & Buchtel, 2009). There is also a difference in the personalities that are encouraged in various cultures. The individualism of U.S. culture encourages extraverted and asser- tive behavior that would be frowned on in more interdependent collectivist societies (Triandis, 2001). Personality traits also change from one generation to the next; for example, based on test scores, U.S. students have been increasing not only in self-esteem and extraversion but also in anxiety and neuroticism (Twenge, 2000, 2001; Twenge & Campbell, 2001). Much remains to be done to understand adequately the role of social influences on personality, but we can be sure that some of the motivations that direct people are shaped by their culture.

PERSONALITY DEVELOPMENT

Another major issue in personality theory concerns the formation and change of personality. To what extent is personality influenced by biological factors, such as heredity? To what extent can personality change as a result of learning? How critical

are the childhood years for personality development, and how much change can occur in adulthood? How do we change personality in the direction we would like, to turn high-risk children toward healthier paths of development or to teach ordinary folk to be creative or to be leaders?

Biological Influences

Some children seem to be quiet or energetic or whatever from the moment of birth. Could it be that personality is genetically determined? The term temperament refers to consistent styles of behavior and emotional reactions that are present from infancy onward, presumably because of biological influences. As long ago as ancient Greece, philosophers and physicians believed that inborn predispositions lead one person to be melancholic and another sanguine (Kagan, 1994). Evidence supports the claim that personality is significantly influenced by heredity. With the explosion of research in genetics and neuroscience, personality researchers are identifying biological mecha- nisms that contribute to such aspects of personality as the tendency for some people to be outgoing and others to be shy. However, we should keep in mind that biology plays out its influence in the environment, and different environments can make quite different personalities out of the same biological potential.

Experience in Childhood and Adulthood

Personality develops over time. Experience, especially in childhood, influences the way each person develops toward his or her unique personality. Many of the major personality theories described in this text make statements about the development of personality. Theorists in the psychoanalytic tradition, for example, emphasize the experience of the preschool years in forming personality. Theories in the learning tradition focus primarily on change, but even some of them (e.g., Staats, 1996) propose that early learning can significantly influence the course of personality throughout life by developing essential skills on which later experience builds. In the emotional domain, early development of bonds of attachment with the parents is receiving con- siderable attention and is widely thought to influence relationships with people into adulthood. Although people do change, considerable evidence indicates the stability of personality over a person’s lifetime (e.g., McCrae & Costa, 1984).

TO THE STUDENT At the beginning of each chapter is a preview of its theory based on several of the issues just discussed. The issues often overlap. For example, cogni- tive processes not only are dynamic but also can be considered descriptive, because individuals differ in them, and developmental, because they change over time. You might begin your study of personality by considering what you believe about these issues based on your own life experience, trying to answer the questions in Table 1.2. Then, to get a preview of the field of personality, browse through the previews at the beginning of each chapter. Do some theories match your ideas more than others do? Do you find new or puzzling ideas in these preview tables? This formal study of personality ideally will offer you new ideas and help you think critically about those you already believe.

THE SCIENTIFIC APPROACH

Personality theorists, like psychology theorists more generally, test their assertions about people through the scientific method. The scientific method requires system- atic observations and a willingness to modify understanding based on these observa- tions. The assumption of determinism is central to the scientific method. Determinism refers to the assumption that the phenomena being studied have causes and that empirical research can discover these causes.

In the scientific method, two different levels of abstraction are important. In Figure 1.1, two abstract concepts are proposed at the theoretical level, “self-esteem” and “social responsibility.” The theoretical proposition “High self-esteem causes social responsibility” asserts that a cause–effect relationship exists between these two concepts. Abstract concepts cannot be directly observed. They do, however, correspond to observable phenomena, indicated at the observable level in Figure 1.1. At the observable level, people who score high on a self-esteem test should like

themselves, talk about their successes, smile, and dress nicely; the opposite behaviors will be observable among people who score low on a self-esteem test. Furthermore, the high self-esteem people should also be observed engaging in behaviors that are observable evidences of the abstract concept of social responsibility. They should obey laws, join political groups, recycle, and score high on a test of social responsibil- ity. People who are low in self-esteem should engage in the opposite behaviors. Clear scientific language makes explicit what we observe and what abstract theoretical ideas predict and explain those observations.

Theory

A theory is a conceptual tool for understanding certain specified phenomena. It includes concepts (theoretical constructs) and statements about how they are related (theoretical propositions). The concepts of a theory are called theoretical constructs. One kind of theoretical construct already mentioned is a personality trait. Traits are often considered to be the underlying units of personality. Examples of traits include shy, intelligent, and athletic. Because traits are assumed to remain constant and determine behavior, people are expected to behave consistently at different times and in different situations.

Traits, like all theoretical constructs, are not themselves directly observable. They are related to observable behaviors through operational definitions, statements identifying what observable phenomena are evidence of a particular trait. In Figure 1.1, the trait self-esteem is operationally defined to correspond to various observable behav- iors: talking about successes (rather than failures), dressing nicely (rather than poorly), and scoring high on a self-esteem test (rather than scoring low). Each trait or other theoretical construct can have many different operational definitions. Because they all correspond to the same trait, we would expect these observations to be positively correlated with one another.

A theory contains various theoretical propositions, which tell how the constructs are related. For example, in Figure 1.1 the theoretical proposition diagrammed hypoth- esizes that “self-esteem causes social responsibility.” Both self-esteem and social respon- sibility are theoretical constructs, and as such they are abstract conceptual tools that cannot be directly observed. Theoretical propositions are also abstract statements and are not themselves directly observable (cf. Clark & Paivio, 1989).

To test a theory, predictions about observable phenomena are logically derived from the theoretical propositions. Consider the example of a classic theoretical proposition in psychology that states, “Frustration leads to aggression.” When this proposition is stated in terms of observable phenomena (i.e., in terms of the constructs as operationally defined), we have a hypothesis, which can be tested by empirical observation (see Figure 1.2).

Research tests whether hypotheses are confirmed by actual empirical observa- tions. Does the abstract theoretical world accurately predict what actually takes place in the real world? The more reliably hypotheses derived from a theory are tested and confirmed by empirical research, the more confidence we have in the theory. When observations differ from prediction, the theory is disconfirmed. If this occurs often, the theory will be revised to make it more accurate, or it may even be abandoned.

Criteria of a Good Theory

Theories are always somewhat tentative. Elementary students of science know this when they differentiate between theories and facts, the latter being more definite and less arguable than theories. (Such elementary students commonly have the miscon- ception that when we become certain of our theories, they will be considered facts. This misunderstanding stems from ignorance of the difference between the theoretical level and the level of observables presented earlier in this chapter. Facts are always at the level of observables; theories never are.) Because theories are abstract, a certain amount of ambiguity can be expected, compared to the concrete details that come as factual observations. Not all theories are equally valuable, however. How can we decide whether a theory is worthwhile?

Several criteria are generally accepted for evaluating scientific theories. That is not to say that individuals always base their personal theoretical preferences on these criteria. Psychology majors, for example, report that they prefer theories that help them understand themselves (Vyse, 1990). It may take effort to apply the more impersonal criteria that we discuss next, but the effort is worthwhile. These criteria guide psychol- ogy from intuitive knowledge toward a firmer scientific base.

VERIFIABILITY The most important criterion is that a theory should be verifiable, that is, testable through empirical methods. Theoretical constructs must be defined with precision so it is clear what is meant by the construct. The operational definitions must be clear and reliably measurable. Operational definitions may include written tests, clinical judgments, interpersonal ratings, observations of behavior, and other well-specified ways of making observations.

The theory must predict relationships among these measurements so clearly, in the form of hypotheses, that observations can be made to support or refute the prediction. If we specify what evidence would support a theory and what evidence would refute, or “falsify,” it, we can use science to evaluate the theory. Philosopher of science Karl Popper (1962) elaborated on this criterion, and he criticized Freud’s theory—which we will discuss in Chapter 2—as “pseudoscience” because it did not meet this criterion; however, his criticism is not without its own critics (Grünbaum, 2008). Disconfirmation is particularly important for advancing science. It is always possible to find supportive evidence for a vaguely formulated theory. The criterion of verifiability requires that we also identify evidence that would refute the theory.

COMPREHENSIVENESS Other things being equal, a good theory is characterized by comprehensiveness. That is, it explains a broad range of behavior. Most traditional personality theories are broad, comprehensive theories dealing with many phenom- ena: developmental processes in childhood, adaptation or mental health, self-image, social interactions with other people, biological influences, and so forth. In practice, however, if a theory attempts to explain too much, its concepts tend to become fuzzy

and ill-defined so the theory cannot be tested adequately. Although comprehensiveness is a desirable characteristic in a theory, it is less important than empirical verifiability.

APPLIED VALUE A theory that has applied value, offering practical strategies for improving human life, has an edge over theories that are simply intellectually satis- fying. For example, personality theories may suggest therapeutic interventions, guide child care, help select the best employees for a particular job, or even predict what will happen in politics, based on the leader’s personality (Immelman, 1993). As in many fields, personality psychology has both basic and applied interests that are not always integrated. Applied research is conducted to solve practical problems. Basic research is conducted for the purpose of advancing theory and scientific knowledge.

OTHER CONSIDERATIONS: PARSIMONY AND HEURISTIC VALUE Besides the three impor- tant criteria of verifiability, comprehensiveness, and applied value, theories that are parsimonious and have heuristic value are preferred. A parsimonious theory is one that does not propose an excessive number of narrow constructs or propositions if a smaller number of broad constructs could explain the phenomena under consider- ation. To do so makes the theory unnecessarily complicated. However, humans are complex creatures, so a theory with too few constructs or propositions may be too simplistic to permit detailed prediction.

The ability of a theory to suggest new ideas for further theory and research is called its heuristic value or fertility (Howard, 1985). Scientific understanding is not static. Scientists build on the work of earlier scientists, moving toward an improved understanding. Just as artists replace rough sketches with more elaborate drawings, theories are replaced by their more polished successors.

Relationship between Theory and Research

Research and theory building in personality ideally go hand in hand. At the level of theory, constructs and theoretical propositions are proposed. By a process of deductive reasoning, hypotheses are derived and, through research, tested.

Theory leads to research. The converse is also true: Research leads to theory (Gigerenzer, 1991). Unexplained observations lead scientists to think inductively. They then suggest new or revised theoretical constructs and propositions. Theory without adequate research becomes stagnant. Research without adequate theory can wander aimlessly.

Scientific development of theories must advance against the complication that people are, in their everyday lives, informal personality theorists. Everyday unscientific beliefs about personality are sometimes called implicit theories of personality. We assume that certain phenomena that we have seen are accompa- nied by other personality characteristics. Attractive people, for example, are often assumed to be warm and trustworthy. Many undergraduates base sexual decisions on implicit personality theories, believing they can assess HIV status by appearance and other irrelevant factors (Williams et al., 1992).

Implicit personality theories are not necessarily incorrect. Physical attractive- ness and interpersonal traits such as extraversion and agreeableness, for example, are correlated (Meier et al., 2010). Some researchers believe they often correspond to the formal theories that have been derived from extensive research (Sneed, McCrae, & Funder, 1998). There is no guarantee of their accuracy, though. Well-planned research studies are necessary to test, and sometimes to correct, errors emanating from implicit theories.

METHODS IN PERSONALITY RESEARCH

Throughout its history, personality research has used a variety of research methods: personality scales and questionnaires, projective techniques, observer judgments, and laboratory methods. In addition, biographical analyses and case studies permit

investigations of individuals, and various biological measures, such as genetic analy- sis, attest to the increasing attention to biological aspects of personality.

Personality Measurement

Measurement of personality involves operationally defining theoretical constructs by specifying how they will be assessed. The most common type of measurement is the self-report personality test, which asks many questions, often in multiple-choice format, under a standard set of instructions. It is not difficult to write personality test items; you have probably seen so-called pop psychology personality tests on the Internet. However, establishing their value is more difficult. What constitutes sound measurement?

RELIABILITY Measurement should yield consistent scores from one time to another. Such reliability is determined in several ways. Test-retest reliability is determined by testing the same subjects on two occasions and calculating the extent to which the two scores agree. Do the same people who score high on the first occasion also score high the second time? They will if the test is reliable. Could it be, though, that they simply remember how they answered the first time (even if they were guessing), which is why the scores do not change? The method of alternate forms reliability gets around this problem by giving different versions of the questionnaire on each occasion. What if subjects are tested only once? In this case, researchers can estimate reliability by calculating subscores based on two halves of the question- naire. Generally, all the odd-numbered items are added together for one score and all the even-numbered items for the other score. The correlation between these two subscores is called split-half reliability.

Problems of unreliability can result from several factors. Short tests are generally less reliable than longer tests. Tests combining unrelated items are less reliable than those composed of closely correlated items, or homogeneous items. Other factors that reduce reliability are ambiguously worded test items and uncontrolled factors in the test- taking situation that influence responses. In addition, real change can occur between the two times that the psychological characteristic is measured, although perhaps in this last case it would be better to speak of personality change rather than unreliability of measurement.

VALIDITY Someone could claim to assess your intelligence by measuring the circum- ference of your head, or your morality by examining your skull for bumps in particular locations, as phrenologists once did. Undoubtedly, except in very unusual cases, these would be quite reliable measures. Yet we would not accept them. Such measures might be reliable, but they are not valid.

Test validity is present if a test really measures what it claims to measure. Whereas reliability can be assessed straightforwardly, determining validity is more challenging. Predictive validity is established if a test predicts a behavior that the researcher accepts as a criterion for the construct being measured (e.g., if a test of assertiveness predicts the number of times a person initiates conversations). In the known groups method, a test is given to different groups of people who are known to differ in what the test measures. For example, a test of mental well-being should produce higher scores among college students than among psychiatric patients (Hattie & Cooksey, 1984). Employers use a variety of tests when they are deciding which  job applicant to hire, and researchers have studied these tests to determine which have the best validity as predictors of effective employee selection. They have found that tests do improve selec- tion over simply using employment interviews (Schmidt & Hunter, 1998). However, test validity can be reduced by several factors, including respondents’ intentional distortion of responses (Furnham, 1990), their misunderstanding of test items, and their lack of knowledge or insight about the material being asked.

Predictive validity focuses primarily on the validity of a particular test. What about the validity of the theoretical construct: construct validity? This question

goes beyond measurement. If a theoretical construct is valid, it will be possible to define it operationally in a variety of ways, and we would expect these vari- ous measures to be correlated. Furthermore, the relationships of the construct with other variables, which are predicted by theory, should be similar regardless which particular measure is used. Consider this imaginary example: If a researcher finds that a new form of therapy reduces patients’ anxiety when measured by a self-report but increases their anxiety when a behavioral observation is used instead, we would doubt the construct validity of anxiety. Perhaps one or both of the measures is defec- tive. Perhaps anxiety is not the one unified combination of behavior and experience that we thought. Until compelling evidence indicates that two measures are com- parable, it is best to limit our claims of validity to each measure separately, or, to use Jerome Kagan’s apt phrase, “validity is local” (1990, p. 294). However, if several research studies using a variety of measures present converging lines of evidence for the usefulness of a theoretical construct—for example, if many studies using various measurement methods find that the new therapy reduces anxiety—we can make the important and bold claim that construct validity (of anxiety) has been established (Cronbach & Meehl, 1955).

MEASUREMENT TECHNIQUES Various measurement techniques have been used in personality research. Usually, subjects are asked to provide some sorts of verbal statements that are analyzed.

Direct self-report measures ask subjects to respond to specific questions, generally in multiple-choice format. They may be either questionnaires (that measure one trait or construct) or inventories (that measure several traits or constructs, e.g., the California Personality Inventory and the Minnesota Multiphasic Personality Inventory). Self-report measures are easy to administer and often reliable, but they have disadvantages. Subjects may not have enough self-knowledge to provide accurate information. They may inten- tionally give false responses, or they may be influenced by response sets, such as the tendency to agree with items regardless of content.

Alternatively, personality can be measured through indirect methods. When p eople talk or write without having to pick a multiple-choice answer, many of the sources of distortion are reduced. Open-ended questions (e.g., “Tell me about your experiences at college”) or other materials (journals, diaries, letters, etc.) can provide data for researchers to interpret (C. P. Smith, 1992). Projective tests present subjects with ambiguous stimuli (such as pictures or inkblots) to which they respond. The indirect approach can avoid some of the shortcomings of verbal reports. (What sort of imaginative story would you make up about an inkblot to look well adjusted, for example? It’s hard to say!) The indirect approach may reveal material of which the person is unaware, and thus it avoids intentional deception and the limitations of conscious experience.

Behavioral measures are sometimes included in personality research. This type of measurement helps develop an understanding of personality in its real-world context. Observers may watch people in real life or in a laboratory, or subjects can be asked to provide information about their real-life experiences. We have to keep in mind, though, that such self-reports may not always be accurate reports of experience because of forgetting, inattention, distortion, or a variety of other reasons.

Objective measures sometimes play a role in personality research, though not generally for the measurement of personality itself. Consider the research finding  that a person’s anxiety level is correlated with self-reported allergies. Objective allergy tests, such as analysis of serum immunoglobulin E (IgE), find no relationship with anxiety. It seems that the self-reports were not accurate (Gregory et al., 2009).

Test scores are important data in personality research, but they can be misleading. Any test score may be inaccurate for a variety of reasons. Tests that are valid for adults may not be valid for children; tests that are valid for majority cultures may be biased when applied to minorities. Convergence across a variety of types of measures is more convincing than single method research.

12

Correlational Studies

Correlational research, which measures two or more variables to study how they are related, is common in studies of personality. Sometimes two measures are used to operationally define a single theoretical construct; in such a case, these measures should obviously be correlated. At other times, two different theoretical constructs are predicted to be correlated because theoretical propositions describe one as causing the other (e.g., “Frustration causes aggression”).

Causes and effects should be correlated; but there is no guarantee that when two variables are correlated, one is the cause and the other is the effect. Correlational research cannot provide strong proof of causation. Two observations can be correlated because one causes another, or because both are caused by a third variable. For example, suppose a correlational research study finds that two variables are associated in a study of elemen- tary school children: number of hours of television watched (variable A) and children’s aggressiveness, determined by observing behavior on the playground (variable B). What can we conclude based on this correlational research? First, it is possible that A causes B; that is, watching television increases the children’s aggressive behavior. Second, it is possible that B causes A: Friends may reject aggressive children after school, and, hav- ing no one to play with, they watch television instead. Third, it is possible that another variable, C, causes both A and B, leading to their correlation without either causing the other. What might such a third variable be? Perhaps having neglectful parents causes children to watch more television (because they are not encouraged in other activities that would place more demands on their parents) and also causes them to be aggres- sive on the playground (because they have not been taught more mature social skills). The point is that correlational research is always ambiguous about the causes underlying the associations observed. From such a study it is not clear that aggressiveness could be reduced by limiting television, by increasing parental attention, or by changing any of the other potential causes that could account for the relationship. Causal ambiguities can be resolved through another research strategy: experimentation.

Experimentation

In true experimental research, hypothesized cause–effect relationships are put to a direct test. An independent variable, which the researcher suspects is the cause, is manipulated by the researcher. An experimental group is exposed to the independent variable. A control group is not exposed to the independent variable. Everything else about the two groups is kept equal: their characteristics that they bring into the study, and the way they are treated during the research. The groups are formed by random assignment to make everything equal that they bring to the study, and care is taken to be sure that there are not extraneous uncontrolled variables that occur during the research, such as different expectancies based on knowing which group is expected to change. After the manipulation of the independent variable, the two groups are then compared to see whether they have different scores on the dependent variable, which is the hypothesized effect.

An experiment could be conducted for the preceding example to test whether watching a lot of television causes an increase in aggressive behavior. An experimental group would be assigned to watch a great deal of television. A control group would watch little television. Then their aggressive behavior on the playground would be observed. If watching television (the independent variable) is the cause, there will be differences between the two groups in their level of aggression (the dependent variable). If some other variable is the cause, the two groups will not differ in aggres- sion, since all other variables were made equivalent between the groups by random assignment.

Logically, it is easier to imagine situations as independent variables in an experi- ment than personality. It is fairly easy to manipulate television viewing. In contrast, how could we manipulate aggressiveness, a personality trait, if we believe the trait of aggressiveness is the cause of aggressive behavior? Most often, this is not possible because research participants bring their personalities to the research, and all the researcher can do is measure them. Indeed, few personality studies use experimental

methods (Revelle & Oehlberg, 2008). One strategy, however, is to change person- ality for an experimental group through some kind of situational manipulation or therapy program. Mischel (1992) and Bandura (1986b) have conducted experimen- tal research in which situations or training interventions are manipulated to change aspects of personality and then effects on behavior are observed. Similarly, a program of research by McClelland and Winter (1969) changed businessmen’s trait of “need for achievement” through a training program and found that this change brought about changes in their business activities. Experimental techniques have occasionally been used by psychoanalytically oriented researchers who have experimentally aroused unconscious material to investigate psychodynamics (e.g., Shulman & Ferguson, 1988; Silverman, 1976). Nonetheless, experimental research in personality is conducted less often than correlational research, in which personality is measured rather than manipulated.

Constructs derived from experimental research are not necessarily interchange- able with those derived from correlational research (Brogden, 1972; West, 1986). For example, a generally anxious person (with a trait of anxiety) may not be comparable to a generally calm person who is temporarily anxious because of a crisis (with a temporary state of anxiety).

Studying Individuals: Case Studies and Psychobiography

When researchers study individuals instead of groups, they often describe their observations in ways that remind us of people telling their life stories. These narra- tives are often rich in detail and imagery, and they can convey emotional insights in ways that more statistical data cannot. A case study is an intensive investigation of a single individual. For example, a clinician may describe an individual client (Gedo, 1999), or an educational psychologist may describe an individual child. When the focus is on theoretical considerations, case studies are called psychobiography. In psychobiography, the researcher often works from archival data, such as letters, books, and interviews, rather than directly interacting with the person being described.

The analysis of individuals is occasionally prompted by practical, even political, considerations. For example, in 1943 U.S. government officials requested a psycho- logical analysis of Adolf Hitler (Runyan, 1982), an analysis that was later published (Langer, 1972). In the early 1960s, a similar request was made for an analysis of the Soviet leader Nikita Khrushchev (Mack, 1971). When a person has died and suicide is suspected, a “psychological autopsy” may be carried out to help determine whether the case was a suicide, and if so, why it occurred (Brent, 1989; Kewman & Tate, 1998; Otto et al., 1993).

Studies of individuals using nonexperimental methods lack both the statistical advantages of large correlational studies and the advantages stemming from con- trol of independent variables in the experimental method. Without these controls, alternate interpretations of the same material are possible (Runyan, 1981), making definitive analyses elusive. Despite the difficulties, case studies are invaluable if we are to be sure that our theoretical concepts do indeed help us understand individual personality dynamics.

William McKinley Runyan defines psychobiography as “the explicit use of formal or systematic psychology in biography” (1982, p. 233). Much psychobiography in the past has been based on psychoanalytic theory. The founder of psychoanalysis, Sigmund Freud (1910/1957), wrote the first psychobiography: a study of Leonardo da Vinci. Ironically, Freud did not follow the standards of sound psychobiography that he set out in the same work (Elms, 1988). Psychoanalysis warns that subjective factors (transference) can be a source of error in psychobiography (Schepeler, 1990). Psychoanalytic theory has been the predominant theory guiding psychobiographical analyses ever since Freud’s initial effort (e.g., Baron & Pletsch, 1985; Ciardiello, 1985; Erikson, 1958; Freud & Bullitt, 1966). It has shortcomings, however. For one thing, evidence about childhood experience, which is important in psychoanalytic formu- lations, is often poor (Runyan, 1982). The theory often leads to overemphasizing a

particular period, the “critical period fallacy,” or specific life events, “eventism” (Mack, 1971). Also, psychoanalytic theory does not call attention to historical and cultural factors that influence personality (L. Stone, 1981).

Other theories have also guided psychobiography. For example, Raymond Cattell’s theory has been used to analyze Martin Luther and other Reformation leaders (Wright, 1985), and Henry Murray’s theory has been applied to a psy- chobiographical study of Richard Nixon (Winter & Carlson, 1988). Researchers have developed systematic ways to analyze existing materials, such as personal documents, diaries, letters, and dream records (Alexander, 1988, 1990; Carlson, 1981, 1988; Gruber, 1989; McAdams, 1990; Ochberg, 1988; Stewart, Franz, & Layton, 1988). Computer methods for analyzing verbal materials exist, but human judges are still essential in these narrative approaches, making such research extremely labor intensive.

ONE THEORY OR MANY? ECLECTICISM AND THE FUTURE OF PERSONALITY THEORY

Most personality psychologists prefer an eclectic approach, one that combines insights from many different theories. In the language of Thomas Kuhn (1970), no single paradigm serves as a theoretical model accepted by the entire field of person- ality. There are, instead, competing perspectives, including psychoanalysis, learning theory, trait approaches, and humanistic psychology. Some attempts have been made to integrate theories. For the most part, though, theories simply coexist, each develop- ing its own theoretical and research literature. Why?

First, some of this fragmentation is related to larger divisions in psychology between what have traditionally been called the “two disciplines” (Cronbach, 1957, 1975) or “two cultures” (Kimble, 1984) of psychology. One side, which Kimble labels the scientific culture, emphasizes experimentation and studies groups of people (the nomothetic approach), often with respect to narrower aspects of personality. The other side, the humanistic culture, is more interested in individuals (the idiographic approach), especially the whole person, and is willing to compromise experimental rigor and to trust intuitive understanding. The conflict between these two cultures is illustrated by Lilienfeld’s (2010) indictment of trust in intuition as one factor imped- ing the development of psychology as a science. Gregory Kimble (1984) undoubtedly spoke for many psychologists when he expressed pessimism about the chances for achieving an integration of the two orientations (see Table 1.3).

Second, theories may have different areas of usefulness. For example, one theory may be useful for understanding people’s subjective experiences of life, another for predicting how people will behave in given situations. Some theories may help us understand the mentally ill or individuals distraught from overwhelming stress; other theories may be more useful in understanding the creative heights of those who have become highly developed. Theories developed in a middle-class North American or European context may not necessarily be valid in African or Asian cultures, nor help understand people who struggle to simply survive.

Besides the different areas of application, theories specialize in different influ- ences on personality. Some focus on early experience; others on the impact of thought; others on biological influences; and so on. Because diverse psychological processes influence individual personality, and because influences range from the biological to the social, the field of personality may always be more comprehensive than any single theory can encompass.

To be sure, it would be easy to get lost in such theoretical debates, but the subject matter of our discipline always brings us back to people. Past and current personality theories both help and hinder progress toward new theories that explain people. They help to the extent that they provide useful and heuristic concepts. They hinder to the extent that theoretical preconceptions, like implicit personality theories, blind us to new directions. How can we remove such blinders? One suggestion, to borrow advice from the British statesman Benjamin Disraeli, is to

Thinking about Personality Theory

1. Look again at the literary sayings at the beginning of the chapter. Discuss them in terms of the concerns of person- ality theory. For example, do they relate to description, dynamics, or development? Can they be verified? Can you think of any sayings about personality in addition to those quoted at the beginning of the chapter?

2. How important do you think it is for personality theory to be evaluated according to scientific criteria? Is the scientific method too limiting?

3. What implicit ideas about personality, besides those men- tioned in the text, might produce bias when we think about personality?

4. Look at the preview tables for the coming chapters. Which of these theories most appeal to you? Why?

The psychoanalytic perspective on personality is one of the most widely known outside of psychology. Within psychology, it has steadfast adherents and forceful critics. The central idea of the psychoanalytic perspective is the unconscious. Simply put, this concept says that people are not aware of the most important determinants of their behavior. Self-understanding is limited and often incorrect. This concept of an unconscious gives us a way of think- ing about behavior, moods, or other symptoms that seem out of touch with conscious intentions; thus it has been a valuable concept in the therapeutic setting (Piers, 1998).

All psychoanalytic approaches maintain the concept of a dynamic unconscious—that is, one that has motivations or energies and so can influence behavior and experience. Various psychoanalytic theories describe the unconscious differently. Sigmund Freud (see Chapter 2) proposed that the unconscious consists of sexual and aggressive wishes that are unacceptable to the conscious personality. For Carl Jung (see Chapter 3), the unconscious consists of more general motivations, which have spiritual content. Other theorists, including Melanie Klein (1946) and Harry Stack Sullivan (1953), have described the unconscious in terms of the self and relationships with other people, especially the mother as the first “other” the infant encounters—ideas that have influenced neoanalytic theories in Part II of this book.

Despite these variations, psychoanalysts share characteristic assumptions:

1. Personality is strongly influenced by unconscious determinants. 2. The unconscious is dynamic, or motivational, and is in conflict with other aspects of the unconscious and with

consciousness. 3. Early experience is an important determinant of personality.

Psychoanalysis originated in the context of psychotherapy and clinical observation. It did not emphasize the scientific tradition of empirical research, but in recent years more effort has been made to test psychoanalytic ideas, such as repression and defense mechanisms, in controlled studies. The primary data for psychoanalysts consist of reports by patients in therapy. The fact that these inferences are not generally checked for historical accuracy with outside evidence has been the focus of considerable controversy. Psychoanalysts generally doubt that the com- plexities of personality, especially unconscious processes, can be measured by objective instruments. When formal measurement is used, psychoanalysts often employ projective techniques that present ambiguous stimuli, such as inkblots in the well-known Rorschach test, and ask the patients (or research subjects) to say what they see in them. Such techniques are generally less reliable than questionnaires, but their advocates claim that they provide access to deeper levels of motivation not available to conscious awareness.

Another objection is that psychoanalytic theorists have not clearly specified the types of evidence that would refute psychoanalytic theory. The theories often describe conflict between one kind of conscious motivation (e.g., self- control) and an opposite unconscious motivation (e.g., sexual freedom). Any observed behavior is consistent with the theory, simply by interpreting the observation flexibly. If a person behaves with self-control, the conscious is presumed to be the cause; if promiscuity is observed, the unconscious is said to determine this behavior. In poten- tially explaining every observation, psychoanalysis has weakened its scientific status. Scientifically, a theory cannot be tested if no observation is inconsistent with it. It is not verifiable, as explained in Chapter 1. Because its operational definitions are vague, empirical observations are not linked to theoretical constructs in a way that can be clearly specified in advance. Instead, intuition (“clinical insight”) makes these links. Metaphorical thinking occurs where the hard-nosed scientist would prefer concrete, rigorous thinking. This criticism has been levied against psychoanalytic theory for many decades, but in recent years, research on defense mechanisms and other psychoanalytic constructs has increased, closing the gap between clinical theory and science.

Outside of psychology, psychoanalytic theory has influenced art and literature, film, and popular culture. With the decline of traditional religion and mystical thinking, psychoanalysis has, for some, become a way of contacting

the irrational forces within the human personality, which is sufficiently “scientific” to be permissible today. Whether this is a legitimate function and whether psychoanalysis fulfills it adequately are matters to ponder.

Adolf Hitler was probably the most infa- mous tyrant of the twentieth century, perhaps of all time. This charismatic dictator was responsible for the deaths of millions of Jews and others in the extermination camps of Nazi Germany during World War II. Many biographers, often using psychoanalytic theory, have attempted to understand him. One of these analyses, commissioned by the U.S. government during the war in an attempt to learn how to overthrow Hitler, remained secret for decades (Murray, 1943).

Adolf Hitler was born in 1889 in Austria, near the German border. He aspired to be an artist but failed the entrance exam for art school, although he deceived family and friends into thinking he was a student. He earned a meager existence selling small paint- ings and postcards. Later he moved to Germany, which he adopted as his homeland, and where he served in the Bavarian army in World War I, although without much success. In the period of discontent following Germany’s defeat in the war, he became active in politics and dreamed

of a restoration of German glory. Elected as chancellor of Germany in 1933, he soon invaded neighboring countries; the hostilities escalated to become World War II. Far from restor- ing German glory, the result of Hitler’s ambitions was the destruction of cities throughout Europe and the extermi- nation of millions of Jews and other prisoners in concentration camps. In the face of defeat in May 1945, Hitler; his lover, Eva Braun; and some close associates committed suicide.
