Gender and the self-presentation of academic achievement

Two experiments were conducted in which first-year male and female subjects (75% white; 25% minorities) at a highly selective liberal arts college predicted their first-semester grade point averages (GPAs). The first experiment varied whether predictions were given publicly or privately when an incentive for accuracy was either present or absent. Whereas the actual GPAs obtained by women did not differ from those obtained by men, women predicted that they would receive lower GPAs than men predicted, but only in the public condition. Whether incentive was present or absent did not affect predictions. The second experiment varied whether predictions were given publicly or privately as well as the perceived achievement of the experimenter. Once again, women's actual GPAs did not differ from men's. However, women predicted that they would receive lower GPAs than men predicted, but only when their estimates were given publicly to a low-ability experimenter. Although previous research has concluded that gender differences on performance estimates is attributable to a lack of confidence among women, these results suggest that the gender difference may be (at least partly) attributable to self-presentational style. It appears that women in this study adopted a modest self-presentational style that was motivated by attempts to protect the self-esteem of the experimenter.We are especially grateful to Rob Abel, David McGill, and Melinda Varn for their help in data collection.     

Validation of the Preschool and Early Childhood Functional Assessment Scale (PECFAS)

Efforts to determine the prevalence of serious emotional disturbance in preschool-aged children have been hampered by the lack of a validated measure. The Preschool and Early Childhood Functional Assessment Scale (PECFAS) is a multi-dimensional measure that assesses the psychosocial functioning of children aged 3–7 years. The concurrent validity and reliability of the PECFAS were assessed in a sample of 30 preschool-aged children in a large Head Start program in Ventura, California. PECFAS ratings based on in-depth interviews were significantly related to parental ratings that the children had mental health problems, psychiatric diagnoses, teacher ratings of the child's need for mental health evaluations, teacher ratings of behavior problems on a standardized screening inventory (DIAL-R), and actual referrals for mental health evaluations. Interrater reliability for the total PECFAS score was high (r = .90) as was internal consistency of the five subscales (alpha = .86). Using the PECFAS scores as a standard, the weighted prevalence of serious emotional disturbance in this West Coast Head Start program was 17%, at the lower end of the current estimated rate of SED for older children in low income samples (18–26%).     

Sexual Peak: Socially Shared Cognitions About Desire,Frequency, and Satisfaction in Men and Women

Is a man’s sexual peak earlier than a woman’s? Three studies were conducted to examine (a) whether the perception that men achieve their sexual peak at a younger age than do women is shared across individuals of different ages and sexes, (b) whether sexual peak is defined differently for men and women, and (c) whether differences between definitions contribute to differences in the age at which men and women are perceived to reach sexual peak. Study 1 suggested that participants believed that females reach their sexual peak at an older age than do males. Study 2 indicated that the defining feature of sexual peak for males was sexual desire and for females was sexual satisfaction. Study 3 suggested that predictions of male sexual peak coincided with participants’ predictions of male age of highest desire and frequency, but not satisfaction, and that female sexual peak coincided with participants' predictions of female age of highest satisfaction but not frequency or desire. Discussion focuses on potential reasons for differences between the perception of male and female sexuality, as well as the social and evolutionary importance of each of the dimensions of sexuality for both males and females.     

The GABAergic effect of low doses of lorazepam on social behavior

The aim of this work was to test the antiaggressive effects of lorazepam and to determine whether these effects were mediated by benzodiazepine receptors. In a first experiment, male mice were injected with lorazepam in a range of low doses (0.05, 0.1, 0.2, and 0.6 mg/kg) or saline solution. In a second experiment, 1 mg/kg of Ro 15‐1788, a benzodiazepine receptor antagonist, and a saline solution were injected before the behavioral test. Results showed that 0.6 mg/kg of lorazepam was the only dose that decreased the total duration of threat (P < .01) and social investigation (P < .05) and that 1 mg/kg of Ro 15‐1788 had no effects. In the third experiment, animals received two injections: 0.6 mg/kg of lorazepam plus 1 mg/kg of Ro 15‐1788, 0.6 mg/kg of lorazepam plus saline solution, or saline solution plus saline solution. Those treated with lorazepam and saline solution spent less time digging (P < .001), threatening (P < .001), and attacking (P < .05) and more time avoiding the opponent (P < .01) or being immobile (P < .001) than the controls. Ro 15‐1788 was successful in completely antagonizing the behavior modulated by lorazepam. Aggr. Behav. 28:248–256, 2002. © 2002 Wiley‐Liss, Inc.     

Peace, scholarship and disciplinary limits: Postcolonial problems and potential in the study of religion

Through its explorations of the work of peace in Sri Lanka, Qadri Ismail's Abiding by Sri Lanka offers both a reconceptualization of democracy and a critique of certain academic disciplines as antithetical to peace and opposition to colonialism. This article considers his criticisms of history and anthropology in order to ask whether, in his terms, it would be possible to have a postcolonial, postempiricist analysis of religion. An exploration of the problems that the study of religion, specifically the category of religion and production of religious authority, pose for Ismail's criteria of postcolonial scholarship points toward the limitations of academic disciplinarity.     

Benefits and Changes for Family to Family Graduates

Family members of people with serious mental illnesses (SMI) need information and support to cope with the considerable stresses they experience. The Family to Family Education Program (FtF) is a structured, peer-led, 12-week information and support self-help class for such individuals. Previous research by Dixon et al. (2004) shows reduced subjective burden and increased empowerment among graduates. The present study sought to understand what processes take place during FtF participation that might lead to these benefits, as a first step in building a conceptual model of how FtF causes its effects, using semi-structured interviews with 31 FtF graduates. Qualitative data analysis suggested that new factual and emotional information from FtF shifts interviewees' understanding of their situation and that skills acquired through FtF then allow participants to incorporate these new perspectives into more adaptive behaviors. These changes led to both proximal and distal benefits for the FtF participants interviewed. The results are discussed in the context of self-help, stress-and-coping, and trauma recovery theories.     

Estradiol or diarylpropionitrile administration to wild type, but not estrogen receptor beta knockout, mice enhances performance in the object recognition and object placement tasks

Cognitive processes mediated by the hippocampus and cortex are influenced by estradiol (E₂); however, the mechanisms by which E₂ has these effects are not entirely clear. As such, studies were conducted to begin to address the role of actions at the β form of the intracellular estrogen receptor (ERβ) for E₂’s cognitive effects in adult female mice. We investigated whether E₂ improved performance of wild type (WT) and ERβ knockout (βERKO) mice in tasks considered to be mediated by the cortex and hippocampus, the object recognition and object placement tasks. WT and βERKO mice were ovariectomized (ovx) and E₂ (0.1 mg/kg), an ERβ selective ER modulator (SERM), diarylpropionitrile (DPN; 0.1 mg/kg), or oil vehicle was administered to mice following training in these tasks. We hypothesized that if E₂ has mnemonic effects, in part, due to its actions at ERβ, then WT mice administered E₂ or DPN would have improved performance compared to vehicle WT controls, which would not be different from βERKO mice administered vehicle, E₂ or DPN. Alternatively, activation of ERα (with E₂, which is a ligand for both ERα and ERβ) may produce opposing effects on cognition and/or the activation of ERα and ERβ vs. either receptor isoform alone may produce a different pattern of effects. Results obtained supported the hypothesis that ERβ activation is important for mnemonic effects. Ovx WT, but not βERKO, mice administered E₂ or DPN had a greater percentage of time exploring a novel object in the object recognition task and a displaced object in the object placement task. Thus, actions at ERβ may be important for E₂ or SERMs to enhance cognitive performance of female mice in the object recognition and placement tasks.
