Changes in Behaviour and Body Weight Following a Single or Double Social Defeat in Rats

In a series of experiments, the consequences of a single and double social conflict on various behaviours and body weight in rats were studied. Animals were subjected to social defeat by placing them into the territory of an aggressive male conspecific for one hour, either once, or twice at the same time on two consecutive days. To assess the consequences of social defeat, three experiments were performed with independent groups of rats. In the first experiment, an open field test was performed two days after the last conflict. Locomotor activity was strongly reduced after social defeat. There were no differences between the single and double defeat group. To assess the effects of social defeat on subsequent social behaviour, a second experiment was performed in which experimental animals were confronted with an unfamiliar non-aggressive rat two days after a single or double conflict. Social defeat resulted in a reduction of social contact with the unfamiliar conspecific. There was no difference between the single and double conflict group. In the third experiment, the effects of social conflict on food intake, body weight and saccharine preference were measured. Food intake was not affected after a single conflict, but in the double conflict group food intake was decreased for several days. Body weight gain was decreased after both single and double social defeat. The decrease was stronger in the double conflict group. Water intake and saccharine preference were not significantly affected. This study revealed that social defeat in rats causes pronounced changes in various behaviours and body weight. Different aspects of behaviour are differentially affected by defeat with respect to the magnitude and time course of the changes induced. Moreover, different behavioural parameters are differentially sensitive to repetition of the stressor.     

Sexual Harassment Severity: Assessing Situational and Personal Determinants and Outcomes1

The current study bridges literatures on sexual harassment, person‐environment systems, and stress and appraisal processes. Conventional wisdom equates severity of sexual harassment with type of harassment. We test this notion empirically and posit a more comprehensive model that examines both person‐ and situation‐level variables. Data came from 13,743 U.S. Armed Forces women responding to survey questions about a significant experience of sexual harassment. Multiple regression results indicate that pervasiveness of sexual harassment relates outcomes better than does type of sexual harassment. Pervasiveness and type interact to predict subjective appraisal of harassment. Additionally, according to multiple‐group structural equation models, appraisal mediates relations between pervasiveness and outcomes. Results further suggest that relations among sexual‐harassment antecedents and outcomes are consistent, regardless of the type of sexual harassment. These findings highlight the importance of examining both persons and situations when assessing sexual harassment severity.     

Slurs, Snubs, and Queer Jokes: Incidence and Impact of Heterosexist Harassment in Academia

Previous research has suggested that overt hostility against sexual minorities is associated with decrements in their well-being. However, subtler forms of heterosexism and their potential effects have been overlooked, heterosexuals have not been asked how they fare in a heterosexist environment, and no research has examined whether women and men might respond differently to heterosexism. Data from 3,128 northwestern US university students (representing all sexual orientations) address these gaps. Approximately 40% reported experiences of heterosexist harassment (HH) in the past year, and those who encountered both ambient and personal HH reported worse psychological and academic well-being than those who encountered no HH. Similar patterns of findings held for sexual minorities and heterosexuals, and for women and men. This paper is based on a presentation given at the American Psychological Association Convention in Toronto, Ontario in August 2003.     

Receipt of interpersonal citizenship: fostering agentic emotion,cognition, and action in organizations

With an eye to fostering an energized and empowered workforce, we explore the discrete emotion of self‐assurance (characterized by boldness, pride, and audacity), investigating how receipt of interpersonal citizenship behavior (ICB) fuels this agentic emotion. ICB includes acts of everyday concern that may be of a person‐ or task‐focused nature. With two survey samples, we propose and test a model that situates self‐assurance as a mechanism linking ICB‐receipt to employee thriving and empowerment. Additionally, we find links to citizenship enactment, as reported by coworkers. Notably, person‐focused ICB‐receipt may be just as beneficial to self‐assurance as task‐focused ICB‐receipt. These results hold equally for working women and men. Our multi‐study, multi‐source results underscore the role of agentic emotion in cultivating a proactive workforce.     

A meta-analytic investigation of conscientiousness in the prediction of job performance: examining the intercorrelations and the incremental validity of narrow traits

Researchers of broad and narrow traits have debated whether narrow traits are important to consider in the prediction of job performance. Because personality-performance relationship meta-analyses have focused almost exclusively on the Big Five, the predictive power of narrow traits has not been adequately examined. In this study, the authors address this question by meta-analytically examining the degree to which the narrow traits of conscientiousness predict above and beyond global conscientiousness. Results suggest that narrow traits do incrementally predict performance above and beyond global conscientiousness, yet the degree to which they contribute depends on the particular performance criterion and occupation in question. Overall, the results of this study suggest that there are benefits to considering the narrow traits of conscientiousness in the prediction of performance.     

Assessing sexual harassment among Latinas: development of an instrument

This study draws from multiple data sources and analytic approaches to offer preliminary evidence on how to assess sexual harassment among Latinas working in the United States, particularly working-class Mexican American women with moderately low acculturation. First, focus group data were collected from 45 Latinas to identify culture-specific manifestations of sexually harassing behavior. These data informed the development of new items for the Sexual Experiences Questionnaire (SEQ: L. F. Fitzgerald et al., 1988), making it more appropriate for administration to Latinas with limited education. A 2nd Latina sample (N = 476) then completed this and other scales in a paper-and-pencil survey. Complete-link hierarchical cluster analyses of the SEQ data, based on a random half-sample of these women, revealed an underlying 3-factor structure. Confirmatory factor analyses on the 2nd half-sample confirmed that this factor model fit the data well, and both the individual factors and the larger scale appear highly reliable. Implications of both new and discarded SEQ-Latina items, the 3-factor structure, and relationships among the factors were discussed.     

Psychological skills and mindfulness training effects on the psychological wellbeing of undergraduate music students: An exploratory study

This study explored the efficacy of psychological skills and mindfulness training intervention on the psychological wellbeing of undergraduate music students. Participants were undergraduate music students (n = 36) from the Department of Music at a South African university, 21 of whom were elected to take the psychological skills and mindfulness training intervention. Data on their self-reported psychological wellbeing, psychological skills, mindfulness and performance anxiety levels were collected pre-and post-intervention. The analysis applied non-parametric procedures to determine changes in students’ psychological wellbeing after the seven-week intervention programme. Findings suggest improvements in psychological wellbeing, psychological skills, mindfulness and performance anxiety with training. Psychological skills and mindfulness training may have benefits to the psychological wellbeing of music students.     

An Evolutionary Outlook on Motivation: Implications for the Clinical Dialogue

A taxonomy of basic motivational systems (reptilian, mammalian, and neo-mammalian), that emerged in phases during the course of millions of years, is proposed. These different phases did not replace each other, but became reorganized in the brain at different hierarchical levels. It is argued that (a) humans are an ultracooperative species and (b) high degrees of cooperation put strong selective pressures toward the development of sophisticated forms of intersubjective communication. These two developments had cascading effects on human evolution, creating both the conditions upon which humans were able to understand intentions, gestures, emotions, and, ultimately, the minds of others, and the emergence of language and symbolic forms of cultural evolution. Possible evolutionary steps that led to this ultracooperative survival strategy and some of their genetic mechanism, with special emphasis on a multilevel model of selection, are described, and the implications for psychotherapy and psychoanalysis are explored.     

The Incidence and Outcomes of Sexual Harassment Among Hispanic and Non–Hispanic White Women: A Comparison Across Levels Of Cultural Affiliation

An extensive body of literature has documented the widespread and damaging nature of sexual harassment among Anglo women, but little attention has focused on the experiences of women of color. The current paper begins to address this gap by comparing sexual harassment incidence rates and psychological and work–related outcomes of Hispanic and non–Hispanic White women across varying levels of cultural affiliation. Chi–square tests of association suggest that risk of harassment increases with affiliation to the mainstream U.S. culture, and hierarchical regression analyses suggest that cultural affiliation moderates the relation between sexual harassment and occupational functioning. These provocative findings are discussed in the context of social and economic vulnerability, socio–sexual norms, and cultural background.
