Acquisition of superexcitatory properties by an irrelevant background stimulus

Six appetitive conditioning experiments with rats demonstrated that an irrelevant X accompanying a negative patterning discrimination (XA+, XB+, XAB-) acquires extraordinarily high levels of conditioned excitation. Responding to X was similar to that evoked by 2 excitors in combination (Experiment 1) and was greater than responding to a separately reinforced Y (Experiments 2-5). Superexcitatory properties were not acquired by X in the nonpatterning discriminations of Experiments 2-4. Experiment 5 found that A and B, if anything, were weakly excitatory. Making them more strongly excitatory after conditioning did not interfere with retention of the original discrimination (Experiment 6). Results support a counterintuitive prediction of associative theories that, under carefully arranged conditions, irrelevant stimuli may acquire superexcitatory properties.     

Associations Between Gender Segregation and Gender Identity in College Students

We investigated associations between gender segregation and the two traditions of gender identity identified by Wood and Eagly (2015): gender-typed personality traits and gender reference group identity. We also investigated whether one of these traditions was associated with gender segregation to a greater extent than the other. Our sample consisted of 73 male (and 93 female undergraduate students aged 18–24 attending a university in the northeastern United States of America. In support of our hypotheses we found that male and female college students reported a greater proportion of same-gender than cross-gender friends and that gender segregation was negatively associated with femininity for male college students and positively associated with gender reference group identity for male and female college students. In addition, as hypothesized, we found that gender reference group identity was associated with gender segregation to a greater extent than gender-typed personality traits. That gender segregation is associated with gender reference group identity to a greater extent than gender-typed personality traits supports a multifaceted model of gender, and it highlights the importance of considering different traditions of gender identity in gender research (Mehta 2015; Wood and Eagly 2015).     

“Doing Gender” and “Doing Religion” in Science: A Cross-National Examination

Women tend to be both underrepresented in science and overrepresented in organized religion, yet the connection between these two phenomena is rarely examined. With survey data collected among 6,537 biologists and physicists from four national contexts—the United States, the United Kingdom, Italy, and India—we test whether science as a social field shapes religious expressions and attitudes differently for men and women. Findings reveal a religious gender gap in India and Italy but not in the United States and the United Kingdom. Further, except in Italy, men had higher odds of perceiving religion and science to be in conflict, believing that their colleagues have a negative attitude about religion, and reporting that science made them less religious. Evidence suggests that men in science may disproportionately internalize normative pressures to masculinize by eschewing religion. Our findings have implications for selection into academic science and the practice of religion among men and women in science.     

Foster Children Caught in Loyalty Conflicts: Implications for Mental Health Treatment Providers

Fifty-two foster parents participated in a two-hour training on the topic of children caught in loyalty conflicts. Prior to and following the training attendees completed measures including one in which they rated their foster children's exposure to 15 different family situations which research indicates are likely to induce feelings of loyalty conflict in children. Analyses of these data indicate that each of the situations was endorsed by between one fourth and one half of the sample. Three-fourths of the foster parents endorsed at least one of the situations, with the average number 5.5. Implications for clinicians working with this population are discussed.     

Righteous Rhetoric: Sex,Speech and the Politics of Concerned Women for America

Abstract

This article considers the Catholic Church's rejection of female sexed bodies as capable of symbolizing Christ in the Eucharist of God's agency in the world. The theories of René Girard provide a useful resource for analyzing the fear of female sexuality within Catholicism. They reveal that an obsessive focus upon sex has been the means through which the male tendency towards sacrificial violence, forbidden within Christianity, has continued to exert a powerful influence. A recognition of this substitutory process would not only enable a revisioning of the roles women and men might play within the Church, but also enable the Church to more effectively oppose the ‘culture of death’ which endangers us all.     

Cognitive enhancement by drugs in health and disease

Attempts to improve cognitive function in patients with brain disorders have become the focus of intensive research efforts. A recent emerging trend is the use of so-called cognitive enhancers by healthy individuals. Here, we consider some of the effects - positive and negative - that current drugs have in neurological conditions and healthy people. We conclude that, to date, experimental and clinical studies have demonstrated relatively modest overall effects, most probably because of substantial variability in response both across and within individuals. We discuss biological factors that might account for such variability and highlight the need to improve testing methods and to extend our understanding of how drugs modulate specific cognitive processes at the systems or network level.     

Achievement Motivation and Adjustment in Members of Indian Scientific Expedition to Antarctica

Twenty-six members are selected to be a part of Indian Scientific Expedition for stay in Antarctica for 16 months in physically challenging, harsh yet adventurous and socially restricted environment. The study highlights the centrality of the need for achievement which influences adjustment of expedition members to harsh climatic conditions. Achievement motivation was assessed in a sample of Indian male expedition members (n=248) in the age group of 22 to 56 years on semi-structured Performa, Sack’s sentence completion test, Multidimensional Personality Inventory and interviews from 1998 to 2008. Results revealed that positive personality characteristics such as high enthusiasm, adaptability, optimistic future orientation and determination and need for achievement, success, high status and monetary compensation influence adjustment and for joining Indian expedition teams motivate people.
