Posterior versus frontal theta activity indexes approach motivation during affective autobiographical memories.

Research has recently identified a promising neurophysiological marker of approach motivation involving posterior versus frontal (Pz - Fz) electroencephalographic (EEG) theta activity PFTA; Wacker, Chavanon, & Stemmler (Journal of Personality and Social Psychology 91:171-187, 2006). Preliminary evidence indicated that PFTA is modulated by dopaminergic activity, thought to underlie appetitive tendencies, and that it indexes self-reported behavioral activation system (BAS) sensitivity. To date, research has largely relied on resting indices of PFTA and has yet to examine the relationship between PFTA and specific approach-related affective states generated by emotionally salient laboratory tasks. Accordingly, the present study evaluated PFTA both at rest and during an ecologically valid autobiographical memory task in which participants recalled personal life experiences involving a goal-striving, an anxious apprehension, a low-point (i.e., difficult), and a neutral memory while EEG data were recorded. In line with prediction, elevated PFTA was observed during both goal-striving and anxious apprehension autobiographical memories. PFTA was particularly elevated during anxious apprehension memories coded as being high on approach-related tendencies. Elevated PFTA during anxious apprehension is consistent with a growing literature indicating that anxious apprehension is associated with elevated approach- and reward-related brain function. Lastly, elevated resting PFTA was positively correlated with self-reported trait anger, a negatively valenced emotion characterized by approach-related tendencies. These results have implications for (a) enhancing our understanding of the neurophysiology of approach-related emotions, (b) establishing PFTA as an index of appetitive motivational states, and (c) clarifying our understanding of the neurophysiology and approach-related tendencies associated with both anxious apprehension and anger.

Introduction: personality psychology and the case study.

This article introduces the Journal of Personality's special issue on the life voyage of Dodge Morgan who, in 1986 at the age of 54, sailed solo around the world in 150 days. Before the voyage, Morgan agreed to participate in an intensive psychological case study, the data for which provide the focus for this special issue. William Nasby and Nancy W. Read have organized the vast array of psychological data obtained from Morgan and produced a complex and illuminating interpretation of his life, drawing liberally from the five-factor trait model of personality and the life-story model of adult identity. This introduction provides a historical and intellectual context for Nasby and Read's study by considering the various ways in which personality psychologists have employed the case study in research and examining the many conceptual and methodological problems and possibilities that arise in the psychological study of the single case.

Generativity among young, midlife, and older adults.

Generativity is conceived as a configuration of psychosocial features constellated around the goal of providing for the next generation. This study used a stratified random sampling of young (ages 22-27), midlife (ages 37-42), and older (ages 67-72) adults to examine age-cohort differences in 4 generativity features: generative concern, commitments, actions, and narration. Although prevailing views on generativity (e.g., Erikson, 1963) predict a peak in midlife and decline thereafter, support for this developmental hypothesis was mixed. Midlife Ss scored higher than young and older Ss on concern and actions in a second administration of measures, but not in the first. Generative commitments and narration showed high scores for both midlife and older Ss and relatively low scores for young Ss. Generative concern, assessed with the Loyola Generativity Scale, was positively associated with life satisfaction.

Construct validity and content analysis.

We clarify points of agreement and disagreement with Schnurr, Rosenberg, and Oxman, as put forth in their article appearing this issue. Speech samples elicited under different conditions may or may not be interchangeable. This is a matter of empirical research, but it is also dependent upon the meaningfulness of the content categories. used in the analysis. We prefer a theory-driven, construct validational approach that employs well validated coding schemes to assess psychologically meaningful concepts.

On the comparison of TAT and free speech techniques in personality assessment.

Schnurr, Rosenberg, and Oxman (1992) recently compared the free speech samples and Thematic Apperception Test (TAT) responses of 95 normal adults. They concluded that the two techniques are not interchangeable, and that the TAT, which proved superior in the prediction of individual differences, may be preferable to free speech instructions for eliciting data in content analytic studies. We disagree with both conclusions. Various forms of narrative speech samples may be highly correlated, so long as psychologically meaningful, well-validated, and higher order content categories are used. The use of first-order content categories is less likely to contribute to the study of personality.

The five-factor model in personality: a critical appraisal.

This critical appraisal aims to position the five-factor model within the multifaceted field of personality psychology by highlighting six important limitations of the model. These are the model's (a) inability to address core constructs of personality functioning beyond the level of traits; (b) limitations with respect to the prediction of specific behavior and the adequate description of persons' lives; (c) failure to provide compelling causal explanations for human behavior and experience; (d) disregard of the contextual and conditional nature of human experience; (e) failure to offer an attractive program for studying personality organization and integration; and (f) reliance on simple, noncontingent, and implicitly comparative statements about persons. The five-factor model is essentially a "psychology of the stranger," providing information about persons that one would need to know when one knows nothing else about them. It is argued that because of inherent limitations, the Big Five may be viewed as one important model in personality studies but not the integrative model of personality.

In search of an everyday morality: the development of a measure.

Current interest in moral theorizing has been dominated by Kohlberg's cognitive-developmental view. Haan (1982) has challenged psychology's reliance on this rationalistic focus and has argued for a rethinking of morality's meaning in accord with everyday human experience. In light of this challenge, the present study gives both theoretical and empirical support to the advancement of a morality for everyday life. Specifically, a new measure called the Visions of Morality Scale (VMS) is reported. The VMS is sensitive to three dimensions which are necessary for an everyday morality: (1) a human constitutive component which is universally experienced by all human beings (empathy); (2) the inclusion of a behavioral component which reflects actual behavior (pro-social inclinations); and (3) a view of morality that is multilevel (private, interpersonal, and social). A brief sketch of the VMS is provided. Results are presented from a study of 181 high school students which relate the VMS to empathy and political orientation. Highly significant relationships were found among morality, political orientation, and empathy. In addition, results revealed numerous sex differences. Finally, the implications of an everyday morality are discussed.

Intimacy, power, and psychological well-being in medical students.

Numerous reports suggest that medical school has adverse psychological effects on medical students, although not all students are affected equally. The authors examined the effects of two social motives, the need for power and the need for intimacy, on measures of well-being and distress obtained throughout the undergraduate years. Medical students high in both power and intimacy motivation were more depressed, neurotic, fatalistic, and self-doubting than were their classmates. These effects began at the end of year 1, peaked in year 2, and disappeared by the end of clerkships. High intimacy-low power students had the highest levels of well-being. These effects were equally true in men and women and both support and render more precise prior role conflict explanations.

Intimacy motivation and subjective mental health in a nationwide sample.

Over 1,200 adults in a representative nationwide sample were administered the Thematic Apperception Test (TAT) and an unstructured interview which produced 25 measures of subjective mental health and ultimately six factor scores: unhappiness, lack of gratification, strain, feelings of vulnerability, lack of self-confidence, and uncertainty. The TATs were scored for intimacy motivation (McAdams, 1980)--a recurrent preference or readiness for experiences of warm, close, and communicative interaction with others. Controlling for age, education, and their interaction, high intimacy motivation in women was associated with greater happiness and gratification, whereas in men it was associated with lack of strain and lack of uncertainty. Women high in intimacy motivation who were living alone reported lower levels of gratification and more uncertainty in their lives than other women. Intimacy motivation also declined significantly over the life span for women, but not for men. Finally, demographic effects on intimacy motivation were examined. Controlling for age, education, and their interaction, professional men (e.g., doctors, lawyers, and teachers) scored higher on intimacy motivation than did men in other occupational categories, while among women the occupational groups with highest intimacy motivation were service workers and craftspersons.

Intimacy motivation and psychosocial adjustment: a longitudinal study.

Longitudinal data of 57 middle-aged men from the Grant Study Adult Development were analyzed in terms of nine indices of psychosocial adjustment and four social motives: achievement, power, affiliation, and intimacy motivation. The Thematic Apperception Test (TAT), administered in 1950-52, was scored for the four motives. Psychosocial adjustment, determined by ratings made primarily with reference to life history data gathered between 1950 and 1967, was comprised of scores on income level, occupational promotion, occupational enjoyment, days of sick leave, marital enjoyment, regular vacations, pastimes with friends, drug or alcohol misuse, and psychiatric visits. High intimacy motivation at age 30 was significantly associated with better adjustment 17 years later. The results are discussed in terms of contemporary theories of psychosocial adaptation.
