Illusions of Safety in a Risky World: A Study of College Students' Condom Use

The role that costs, benefits, and perceptions of invulnerability play in condom use was examined in a sample of students ( N = 211) at 4-year and 2-year colleges. In multiple regression analyses, past condom use was related to relative invulnerability, low present risk, and inexperience. Less intended condom use was associated with high perceptions of relative invulnerability and low perceptions of present risk. It appears that many college students feel protected from HIV because they judge their current sexual environment to be safe due to monogamy, sexual history taking, and the ability to tell a partner's HIV status. Independent of that, feelings of relative invulnerability are associated with more condom use—perhaps an accurate judgment of past risky behavior.     

Longitudinal changes in the contribution of genetic and environmental influences to symptoms of depression in older male twins

Genetically informative longitudinal data on self-reported symptoms of depression allow for an investigation of the causes of stability and change in depression symptoms throughout adult life. In this report, the authors investigated the relative contribution of genetic and environmental influences to symptoms of depression in 83 monozygotic and 84 dizygotic male twin pairs from the National Heart, Lung, and Blood Institute (NHLBI) Twin Study. Participants first completed the Center for Epidemiologic Studies-Depression (CES-D) scale in 1985-1986 and again during 1995-1997. Mean age of twins at baseline was 63 years, range 59 to 70. From cross-sectional genetic analyses we estimated the heritability of CES-D to be 25% (95% confidence interval [CI], 11%-39%) at baseline and 55% (95% CI, 40%-71%) at follow-up. Fitting longitudinal genetic models to the two-wave data, we found that stability of symptoms over the 10-year follow-up was due primarily to continuity of genetic influences.     

Qualitative analysis of verbal fluency output: review and comparison of several scoring methods

We compared three approaches to scoring qualitative aspects of verbal fluency performance in 88 healthy young adults. Phonemic and semantic fluency output was scored for word clustering and switching between clusters. Convergent validity analyses using other tests presumed to tap into strategy use (California Verbal Learning Test, Ruff Figural Fluency Test) support scoring of phonemic and semantic clusters on both fluency tasks. Task-discrepant clustering (e.g., semantic clustering on phonemic fluency) may index intentional strategy use on both fluency tasks, whereas task consistent clustering (e.g., phonemic clustering on phonemic fluency) appears strategic only on semantic fluency. Switching can be decomposed into subtypes that appear to reflect different cognitive processes on phonemic versus semantic fluency. Principal components analyses suggest that earlier scoring methods do not fully capture the "process" aspects of verbal fluency performance.     

Covert discrimination against gay men by U.S. college students.

This study examined the use of sexual orientation as a meaningful social category and the consequences of using this category. The sample consisted of 260 U.S. college students who viewed a video and completed a 29-item scale (L. L. Thompson & J. Crocker, 1990) and the 7-item Homophobia Scale (R. A. Bouton et al., 1987). Results showed that participants' adjective ratings of targets favored gay men. Participants did not exhibit greater bias toward gay men when provided with justification. However, there was a pattern of bias in which participants showed favoritism toward heterosexual male targets when provided with no justification for bias.     

Sex Roles and the Desirability of Job Rewards,Expectations and Aspirations of Male versus Female Salespeople

Abstract

There have been numerous studies of the impact of sex-role stereotyping upon the preferences for job rewards and the difference between men and women. This study tests for such differences in a career field where men and women compete equally—commissioned residential real estate sales. Several new hypotheses were tested to include not only differences in desirability for job rewards, but also the expectancy of success in achieving them. There was little evidence of any differences between men and women in this career field resulting from a sex-role impact.
