Normative Influence Effects on Sexual Arousal to Nonviolent Sexually Explicit Material1

The role of informational social influence in sexual arousal was explored by measuring the effects of normative influence messages on sexual arousal to a nonviolent sexually explicit story in both male and female subjects. The type of message (high versus low arousal), as well as the reference group sex, were varied. The results showed that (a) subjects who received a message that similar others became highly aroused reported a significantly higher level of arousal than subjects who received the opposite message; (b) male subjects reported a significantly higher level of sexual arousal than females; and (c) a normative message from a male reference group had a stronger impact on both male and female subjects than one from the female reference group, indicating that males are perceived as more credible “experts” on matters of sexual responding man females. The study suggests one means by which individuals learn to respond to sexually explicit materials.     

Layoffs,self-esteem,and survivor guilt: Motivational,affective, and attitudinal consequences

The present study explored the effect of layoffs on the subsequent productivity of “survivors”. All participants performed a proofreading task either after witnessing the dismissal of a co-worker (Layoff condition) or not (No-Layoff condition). Consistent with equity theory, the quantity of workers' performance was greater in the Layoff than in the No-Layoff condition. A Worker Self-Esteem × Layoff interaction effect revealed that the Layoff effect was entirely attributable to the low, rather than the medium or high, self-esteem participants. Additional analyses revealed that the layoff caused participants to (1) experience increased feelings of remorse and (2) develop more negative attitudes toward their co-worker, both of which are also consistent with equity theory. Practical and theoretical implications are discussed.     

EFFECTS OF ALCOHOL INTOXICATION AND VICTIMIZATION HISTORY ON WOMEN'S SEXUAL ASSAULT RESISTANCE INTENTIONS: THE ROLE OF SECONDARY COGNITIVE APPRAISALS

This study used an experimental paradigm to investigate the role of secondary cognitive appraisals in women's sexual assault resistance and whether these appraisals mediated influences of alcohol and prior victimization. After consuming a beverage (control, placebo, moderate, or high dose), 351 women projected themselves into a simulated interaction with a sexually aggressive man. Four types of secondary appraisals (shock at the man's behavior, concern about his feelings, uncertainty in the situation, conflict about what to do) and three resistance strategies (assertive, polite, passive) were examined. Path modeling revealed that, as expected, intoxication and prior sexual victimization influenced secondary appraisals, which in turn influenced intended resistance. Prior adult sexual assault (ASA) and childhood sexual abuse (CSA) also had direct effects: ASA negatively predicted assertive resistance and CSA positively predicted passivity. Findings suggest that secondary appraisals are key targets for intervention to facilitate effective resistance, thereby reducing the risk of adult sexual victimization.     

Hormonal regulation of delta opioid receptor immunoreactivity in interneurons and pyramidal cells in the rat hippocampus

Clinical and preclinical studies indicate that women and men differ in relapse vulnerability to drug-seeking behavior during abstinence periods. As relapse is frequently triggered by exposure of the recovered addict to objects previously associated with drug use and the formation of these associations requires memory systems engaged by the hippocampal formation (HF), studies exploring ovarian hormone modulation of hippocampal function are warranted. Previous studies revealed that ovarian steroids alter endogenous opioid peptide levels and trafficking of mu opioid receptors in the HF, suggesting cooperative interaction between opioids and estrogens in modulating hippocampal excitability. However, whether ovarian steroids affect the levels or trafficking of delta opioid receptors (DORs) in the HF is unknown. Here, hippocampal sections of adult male and normal cycling female Sprague-Dawley rats were processed for quantitative immunoperoxidase light microscopy and dual label fluorescence or immunoelectron microscopy using antisera directed against the DOR and neuropeptide Y (NPY). Consistent with previous studies in males, DOR-immunoreactivity (-ir) localized to select interneurons and principal cells in the female HF. In comparison to males, females, regardless of estrous cycle phase, show reduced DOR-ir in the granule cell layer of the dentate gyrus and proestrus (high estrogen) females, in particular, display reduced DOR-ir in the CA1 pyramidal cell layer. Ultrastructural analysis of DOR-labeled profiles in CA1 revealed that while females generally show fewer DORs in the distal apical dendrites of pyramidal cells, proestrus females, in particular, exhibit DOR internalization and trafficking towards the soma. Dual label studies revealed that DORs are found in NPY-labeled interneurons in the hilus, CA3, and CA1. While DOR colocalization frequency in NPY-labeled neuron somata was similar between animals in the hilus, proestrus females had fewer NPY-labeled neurons that co-labeled with DOR in stratum oriens of CA1 and CA3 when compared to males. Ultrastructural analysis of NPY-labeled axon terminals within stratum radiatum of CA1 revealed that NPY-labeled axon terminals contain DORs that are frequently found at or near the plasma membrane. As no differences were noted by sex or estrous cycle phase, DOR activation on NPY-labeled axon terminals would inhibit GABA release probability equally in males and females. Taken together, these findings suggest that ovarian steroids can impact hippocampal function through direct effects on DOR levels and trafficking in principal cells and broad indirect effects through reductions in DOR-ir in NPY-labeled interneurons, particularly in CA1.     

Six year follow-up of health status changes in Danish adults with suicide tendency in 1994

The purpose of this study was to determine whether suicidal ideation and/ or suicide attempts have any long-term health effects. The relationship between suicidal thoughts and/or a previous suicide attempt in 1994 and the presence of suicidal ideation in 2000 was analyzed. We found that health status in 1994 differed significantly between the groups with and without suicidal ideation or a previous suicide attempt and that the differences persisted or even deepened (not significant) after 6 years. Further, people who had suicidal ideation or a suicide attempt in 1994 had a significantly greater risk (OR = 7.4) of having suicidal ideation in 2000 than people who had not.     

Daily Goals, Life Goals, and Worst Fears: Means, Ends, and Subjective Well-Being

This study addressed the relations among personal strivings (daily goals) and future life goals and worst fears. Eighty undergraduate participants (62 women, 18 men) listed their daily goals, their ultimate life goals, and their worst fears, and completed questionnaire measures of subjective well-being. Daily goals were content-analyzed for relevance to attaining life goals or avoiding worst fears. Daily goals that were instrumental to life goals or that avoided worst fears were rated as more important but also more difficult by participants. Working on daily goals avoiding one's worst fears was negatively related to measures of subjective well-being, controlling for daily goal progress, difficulty, ambivalence, and importance. Working on daily goals that were instrumental to one's life goals only weakly predicted well-being. The avoidance of worst fears interacted with daily goal appraisals such that individuals who experienced little progress at daily goals that served to avoid their "worst case scenario" experienced the lowest levels of subjective well-being. In addition, progress at daily goals that were relevant to accomplishing one's life goals was significantly more strongly related to subjective well-being than progress at daily goals that were unrelated to one's life goals. Results indicate that daily goals are used to enact life goals and avoid worst fears and that these means–end relations have implications for well-being.     

Novel popout without novelty

Localization of a novel word in an array with several familiar words is typically enhanced relative to localization in an all-novel array (between-array novel popout) and sometimes enhanced relative to familiar words in one-novel arrays (within-array novel popout). Christie and Klein (1996) have questioned the reality of the latter effect, suggesting that it may be an artifact of guessing bias. The present Experiment 1 replicated within-array novel popout with the novel word probed at chance (i.e., on only one quarter of trials). Experiments 2 and 3 demonstrated a similar popout effect for a categorically unrelated word among three categorically related words, despite superior performance on all-related arrays relative to all-unrelated arrays. Repetition of constant sets of words within the experimental context is therefore unnecessary for a popout effect, contrary to assertions by Johnston and Hawley (1994). Interitem associations appear to be sufficient to produce a popout effect; as such, “novel popout” appears to be a misnomer for a phenomenon that does not depend on novelty.
