Psychological aspects

Self-concept stability was tested in three studies to examine the relationship between stability in one's self-concept and the ability to adapt to changes in the social environment. Much of the literature on the topic of self-stability emphasizes the functional benefits of stability and the negative outcomes associated with instability. Dynamical systems theory purports however that stability in a dynamical system is indicative of a loss of complexity that limits the range of the systems behavior. Accordingly, this series of studies tests the idea that a stable self-system may have a more limited range of behaviors than unstable self-systems and this may have implications for adapting to changes in one's social environment. The overarching hypothesis is that compared to those with less stable self-views, those with stable self-views will demonstrate lower levels of flexibility of behavior in response to changing social demands. Study 1 assessed the dynamics of participants' evaluations by asking them to complete a self-descriptive recording and evaluate their self-descriptions using the mouse paradigm procedure. Participants also completed a series of questionnaires assessing personality factors and behavioral and cognitive flexibility. Study 2 expanded on the first study by adding a well-validated measure of self-esteem stability and a social conceptualization of behavioral flexibility. Study 3 tested participants' willingness to demonstrate behavioral flexibility in an actual social situation and examined the effects of stress on the relationship between stability and flexibility.

A 'wave of nostalgia' has gripped the US leading to nostalgic fashions, furniture, television programming and even food. The marketing literature suggests that nostalgic-related consumption is the result of an aging population. It has been proposed that the purchase of nostalgic-products and services is an attempt by mature consumers to return psychologically to the ease, certainties and conflict free periods that existed or seemed to exist during their childhood or adolescence. This paper proposes that discontinuity, as argued by Davis (1979), is a better explanation for why people develop a preference for and consume nostalgic goods. Although some insights have been developed, research focused only on mature consumers and is rather limited in offering alternative explanations for the evocation of nostalgic feelings. MANCOVA was the primary method used to test hypotheses. Findings of this study indicate that discontinuity does not necessarily lead to nostalgia and preference for nostalgic products varies.

Empathy has been shown to have many positive outcomes in individuals at every stage throughout life. It promotes sociability, helping behaviors, and can protect against the development of psychopathology. Evolutionary theorists have hypothesized that humans have a biological predisposition for empathic response. Temperament, as well as parental interaction with children, account for individual differences in empathic response levels. Much research has also looked at maternal depression as a key factor in children's negative emotional responding. We used EEG to measure individual differences in children's empathic emotional responding, as well as parental interaction and its impact on empathy and prosocial development. Results show that children rated as being more sociable are more likely to show outward expressions of empathy. Also, those with greater right frontal asymmetry are more likely to assist others in a prosocial manner.

The purpose of this study was to investigate the self-directed learning (SDL) readiness of third-year medical students in comparison to previously reported scores for the general population; the relationship between SDL readiness and knowledge-based and performance-based measures of success in a medical school using an integrated medical curriculum; and to determine if knowledge-based and performance-based measures of success are significant in predicting Self-Directed Learning Readiness Survey/Learner Preference Assessment (SDLRS/LPA) and National Board of Medical Examiners Family Medicine Shelf Examination (NBME-FM) scores. This study analyzed SDLRS/LPA scores, knowledge-based scores (NBME-FM), performance-based scores (Objective Structured Clinical Examination [OSCE] and preceptor rating), and a combination of knowledge-based and performance-based scores (final grade). Analyses of 873 students resulted in mean scores of 229.06 + 23.19 for the SDLRS/LPA. Correlations were significant (p < .05) for SDLRS/LPA scores to NBME-FM scores (r = .073, p < .05). OSCE scores (r = .133, p < .01), and final grade (r = .138, p < .01). Regression analysis revealed that the total model of NBME-FM, OSC AVG, and preceptor rating predicted 2.1% of the variation in SDLRS/LPA, which was significant (p < .01). Regression analysis revealed that SDLRS/LPA, OSC AVG and preceptor ratings predicted 9.7% of the variance in NBME-FM, which was significant (p < .001). The results support previous findings that medical students' levels of SDL readiness are higher than the general population mean of 214.0 + 23.49.

The purpose of this investigation was to determine the effects of a pedometer-based intervention on physical activity and self-efficacy among community college students in wellness classes (N = 154). The intervention included a pretest/posttest physical activity questionnaire, pedometer use, weekly goal setting and self-report of step data via the web. The experimental group wore pedometers daily for ten weeks; the control group wore pedometers for one week at baseline and week ten. Average weekday physical activity increased 29% for the experimental group and decreased 16% for the control group. Data analysis demonstrated a statistically significant difference due to the treatment regarding step count, differences in mean scores for self-efficacy, and a main effect for treatment for BMI. These results support the effectiveness of pedometer use to increase physical activity and self-efficacy in conjunction with a community college health curriculum.

The cruelty of Military Police guards at Abu Ghraib prison contributed to American shame and questions regarding how such cruelty emerges. The accepted approach of "situational attribution theory" - based upon Zimbardo's (1973, 2007) social psychological perceptions and results of the Stanford Prison Experiment - proposed that personality or "disposition" has little role in the emergence of such cruelty. Termed "institutional cruelty," this manuscript presents the possibility that understandings and preventive measures afforded by situational attribution theory can be extended via acknowledgement of a greater role played by disposition. Psychoanalytic and object relations approaches are presented to this end. The manuscript addresses the most puzzling characteristics of institutional cruelty: 1) rapidity of onset, taking days or, at most, weeks for initial expression, 2) emergence in ordinary, normal individuals, and 3) emergence in the "mock" situation of the Stanford Prison Experiment. Criminological, organizational culture, and social psychological theories are explored for their application to institutional cruelty.

This study uses Karlyn Campbell's concept of feminine rhetorical style as a theoretical framework for analyzing the rhetoric of Barbara Bush's 1990 Wellesley College commencement address. Through a systematic evaluation of Barbara Bush's speech, this study reveals that her rhetoric exemplifies feminine rhetorical style. The analysis also concludes that Barbara Bush's personal tone, specifically her use of narrative and humor, is the most useful and effective characteristic of her feminine rhetorical style. Using feminine rhetorical style, Barbara Bush successfully dissipates some of the tension she faced prior to the graduation ceremony at Wellesley College. Therefore, this study reveals that feminine rhetorical style is an attractive alternative for speakers seeking to build identification in hostile situations when identification is, or appears to be, lacking.

This research examines the U.S. media during the 1999 Women's World Cup from a feminist postcolonial standpoint. This research adds to current feminist scholarship on women and sports by de-centering the global North in its discourse. It reveals the bias of the media through the representation of the United States National Team as a universal "woman" athlete and the standard for international women's soccer. It further argues that, as a result, the Nigerian National Team was cast in simplistic stereotypes of race, class, ethnicity, and nation, which were often also appropriated and commodified. I emphasize that the Nigerian National Team resisted this construction and fought to secure their position in the global soccer landscape. I conclude that these biased representations, which did not fairly depict or value the contributions of diverse competing teams, were primarily employed to promote and sell the event to a predominantly white middle-class American audience.

The fact that 45% of boys and 32% of girls in the United States participate in youth sports suggests that sports participation might be an important influence on children's psychosocial development. This study explored: (1) how children's gender cognitions influence sports self-efficacy and (2) how sports self-efficacy influences children's psychosocial adjustment. Results suggest that for boys, felt pressure to conform to gender standards and the belief that sports is important for boys influence sports self-efficacy. In girls, both the belief that sports is important for girls and the belief that sports is important for boys predicted sports self-efficacy. Sports self-efficacy predicted benefits for girls adjustment (high self-esteem, higher body satisfaction, lower depression and lower anxiety) but both positive and negative outcomes for boys (higher narcissism, higher aggression, and lower depression and lower anxiety). The findings overall suggest that the correlates of sports self-efficacy are somewhat different for boys and for girls.

Women have recurrently faced the adaptive problem of rape over evolutionary history. Little research has investigated the potential evolved psychological mechanisms for rape avoidance that women may possess. Here I review evolutionary perspectives on rape avoidance. I follow this review with the results of two studies conducted to design a measure of women's rape avoidance, known as the Rape Avoidance Inventory (RAI). Study 1A included 99 women who self-reported acts they do or might do specifically to avoid being raped. Study 1B included 144 women who filled out a preliminary inventory of rape avoidance behaviors. I used their responses to construct the RAI. In Study 3, I develop and test a number of hypotheses derived from evolutionary psychological theory, using data derived from the sample of women in Study 1B. I conclude by discussing limitations and possible future directions for rape avoidance research.
