Cortical spreading depression and conditioned taste aversion: an attempt to resolve a controversy

The claim (Winn, Todd, & Elias, Behav. Biol. 19, 55-63 (1977) ) that cortical spreading depression (CSD) can serve as US in the conditioned taste-aversion (CTA) paradigm was experimentally examined. Rats given 15-min access to novel 0.1% sodium saccharin (CS) followed by ip NaCl and bilateral or unilateral CSD (US) displayed similar saccharin preference (54%) as the sham-CSD-treated controls in a multiple-bottle retention test. Rats receiving ip LiCl (0.15 M, 2% body weight) and sham CSD as the US showed marked saccharin aversion. It is concluded that CSD does not elicit CTA and that some claims to the contrary can perhaps be ascribed to CSD-induced disruption of attenuation of neophobia.     

Gender-role orientation and body image in women and men: The moderating influence of neuroticism

This study examined the effects of gender-role orientation on aspects of body image satisfaction in a group of primarily Caucasian young women and men. It also examined whether neuroticism—a broad, higher-order dimension of personality—functioned additively or interactively with gender-role orientation in the prediction of body image. Similar to previous research, masculinity was related to positive body image in women. For men, results were in the opposite direction. Femininity, and not masculinity, was related to body satisfaction. Of particular interest were the findings that neuroticism interacted both with masculinity in women and femininity in men in predicting positive ratings of attractiveness. In both cases, the positive relationship between gender-role orientation and attractiveness only existed at low levels of neuroticism. As neuroticism increased, the relationship diminished; there was no relationship at all at high levels of neuroticism. Results are discussed in terms of the differential significance of gender-role orientation for body esteem in women and men, and with respect to the moderating influence of personality factors.     

Commitment to the environment: the role of subjective norms in college and community samples

We tested a model of antecedents and outcomes of commitment to the environment, defined as psychological attachment and long‐term orientation to the natural world, hypothesizing that satisfaction with, investments in, and subjective norms about the environment would predict commitment, which, in turn, would predict willingness to sacrifice for the environment. In two studies, the model was supported in undergraduate and community samples, and for general commitment to the environment as well as commitment to specific proenvironmental behaviors. Individuals who are satisfied with and invested in the natural world, and who believe that those close to them value it as well, are likely to be committed to the environment and be willing to forego selfish interests to behave proenvironmentally.     

Looking for Trouble: Preventive Genomic Sequencing in the General Population and the Role of Patient Choice

Advances in genomics have led to calls for developing population-based preventive genomic sequencing (PGS) programs with the goal of identifying genetic health risks in adults without known risk factors. One critical issue for minimizing the harms and maximizing the benefits of PGS is determining the kind and degree of control individuals should have over the generation, use, and handling of their genomic information. In this article we examine whether PGS programs should offer individuals the opportunity to selectively opt out of the sequencing or analysis of specific genomic conditions (the menu approach) or whether PGS should be implemented using an all-or-nothing panel approach. We conclude that any responsible scale-up of PGS will require a menu approach that may seem impractical to some, but that draws its justification from a rich mix of normative, legal, and practical considerations.
