Ambiguous Communication of Sexual Intentions as a Risk Marker of Sexual Aggression

Three studies are reported that explored the role of ambiguous communication of sexual intentions as a risk factor for sexual aggression and victimization. Two main forms of ambiguous communication were distinguished: token resistance (saying no when you mean yes) and compliance (saying yes when you mean no). Two samples of heterosexual men and women and a sample of homosexual men with a total N of 1284 completed a measure of sexual victimization or aggression and indicated whether or not they had ever shown token resistance or compliance in a sexual encounter. Moreover, the heterosexual male respondents indicated whether they had ever perceived token resistance or compliance in a female partner. Logistic regression analyses revealed that the risk of experiencing sexual victimization was significantly increased as a function of token resistance. Two of the three studies also showed compliance to be a risk factor for sexual victimization. For the male respondents, token resistance was consistently linked to a higher likelihood of perpetrating sexually aggressive acts in the three studies. Perceived compliance was also found to increase the risk of sexual aggression in three of four analyses. Support for a link between perceived token resistance and sexual aggression was found in the first study only. Overall, the findings suggest that the use of ambiguous communication in negotiating sexual encounters is associated with an increased risk of sexual victimization as well as perpetration of sexually aggressive acts in both heterosexual and homosexual contacts. The implications of the findings are discussed with respect to the issue of rape prevention.     

Another Side to Downsizing: Survivors' Behavior and Self-Affirmation

Downsizing is one of the terms used to describe the efforts of companies to gain a competitive edge. The effects of global competition, mergers, market saturation, and automation are forcing the streamlining of the American workforce. This study addresses the gap in empirical data on the effects of self-affirmation opportunities to employee survivors and victims. Specifically, the conceptual model developed in this research examines the interactive effects of self-affirmation and the perception of procedural justice, distributive justice, and job insecurity on the induced psychological states of the individuals involved with companies engaged in downsizing. The conceptual model suggests that layoffs have an impact on the induced psychological states of the individuals affected. At play in the model is the moderating variable of re-affirmation. This, in turn, will affect the attitudes and work behaviors of those same individuals and their ability to maintain their self-image. Specific recommendations to management, based on these findings, conclude the study.     

Compensating for Cognitive Deficits Following Brain Injury

Two of the most important goals of rehabilitation are to (a) reduce everyday consequences of impaired cognitive functioning (disabilities) and (b) reduce the level of handicap (the extent to which these problems prevent successful return to society). One of the ways by which we can achieve these goals is to enable people to compensate for their cognitive deficits. This paper (i) describes a theoretical framework for understanding compensatory behavior, (ii) discusses different forms of compensation, (iii) considers compensation for several cognitive disorders, and (iv) presents suggestions for predicting which patients will find it easy to compensate and which require more intensive and focused rehabilitation.     

The injustice of excluding laboratory rats, mice, and birds from the Animal Welfare Act

A major shortcoming of the Animal Welfare Act is its exclusion of the species most-used in experimentation -- rats, mice, and birds. Considerations of justice dictate that extension of the law to these three species is the morally right thing to do. A brief history of how these species came to be excluded from the laws protecting laboratory animals is also provided, as well as discussion of the implications and significance of expanding the law.     

Anisomycin infused into the hippocampus fails to block "reconsolidation" but impairs extinction: the role of re-exposure duration

Recent studies have reported new evidence consistent with the hypothesis that reactivating a memory by re-exposure to a training context destabilizes the memory and induces "reconsolidation." In the present experiments, rats' memory for inhibitory avoidance (IA) training was tested 6 h (Test 1), 2 d (Test 2), and 6 d (Test 3) after training. On Test 1 the rats were either removed from the shock compartment immediately after entry or retained in the shock context for 200 sec, and intrahippocampal infusions of the protein synthesis inhibitor anisomycin (75 microg/side) were administered immediately after the test. Anisomycin infusions administered after Test 1 impaired IA performance on Test 2 in animals given the brief re-exposure, but impaired extinction in animals exposed to the context for 200 sec. Rats with anisomycin-induced retention impairment on Test 2 demonstrated spontaneous recovery of retention performance on Test 3, whereas rats showing extinction on Test 2 showed further extinction on Test 3. The findings indicate that post-retrieval administration of anisomycin impairs subsequent retention performance only in the absence of extinction and that this impairment is temporary.     

Dynamic shifts in corticostriatal expression patterns of the immediate early genes Homer 1a and Zif268 during early and late phases of instrumental training

Adaptive motor actions require prior knowledge of instrumental contingencies. With practice, these actions can become highly automatic in nature. However, the molecular and anatomical substrates mediating these related forms of learning are not understood. In the present study, we used in situ hybridization to measure the mRNA levels of two immediate early genes (IEGs) in an instrumental paradigm where rats learned to lever-press for food. We report that after three training sessions, Homer 1a and Zif268 (an effector and regulatory IEG, respectively) were significantly induced within an extensive corticostriatal network relative to untrained controls. With extended training (23 sessions), however, a shift in the expression patterns of the two genes was evident. Expression of Homer 1a (official symbol Homer1) decreased significantly in frontal and cingulate cortices, whereas striatal expression was generally maintained. Interestingly, Homer 1a expression markedly increased with extensive training in the ventrolateral region of the striatum (VLS) relative to early learners, suggesting that plasticity in the VLS is required for the efficient production of the learned behavior or in habit formation. Zif268 (official symbol Egr1) expression generally decreased with extensive training; however, these changes were not significant. These results demonstrate for the first time, on a molecular level, a dynamic shift in the contribution of corticostriatal systems mediating the early acquisition and consolidation of goal-directed responses to those engaged after extensive training.
