THE PERVERSITY OF INANIMATE OBJECTS: STIMULUS CONTROL BY INCIDENTAL MUSICAL NOTATION

Social cognition research suggests that incidental, environmental stimuli (e.g., business suits) can nonconsciously influence the degree to which behavioral dispositions (e.g., competitiveness) are expressed. Similarly, cognitive research suggests that incidental action-related objects (e.g., hammers) can prime action plans that then affect the speed with which a concurrent, intended action (e.g., power grip) is executed. However, whether incidental stimuli can instigate actions that run counter to one's current goals has yet to be determined. Moving beyond indirect effects, we show that such stimuli can directly cause the expression of undesired actions: Incidental stimuli resembling musical notation caused the systematic expression of unintended key presses in musicians, but not in nonmusicians. Moreover, the effect was found even when targets and distracters bore no apparent perceptual or semantic relation. We discuss the implications of these findings for models of action production and for social-cognitive concepts (e.g., applicability) regarding the limits of nonconscious processing.     

Effects of Changing Proportions of the Sexes on Ratings of Occupational Prestige

Touhey (1974) has suggested that an influx of women into high-status, male-dominated professions will result in declining prestige and desirability for those professions. The present study attempts both a replication and an extension to examine results of changing sex ratios in low-status and female-dominated occupations. Replication of the previous finding and its predicted extension to high- status women's jobs occurred only with college sophomores; juniors and seniors generally did not respond to sex composition, although they did rate high-status men's jobs as even more prestigious with a larger proportion of women employed in the job. Results for the low-status jobs were less clear, possibly reflecting the distance of college students from such occupations. Unlike Touhey's, these results are not interpreted as predicting future occupational prestige, but only as reflecting current attitudes about women and men.     

A randomized clinical trial of a manual-guided risk reduction intervention for HIV-positive injection drug users.

This study randomized 90 HIV-seropositive, methadone-maintained injection drug users (IDUs) to an HIV Harm Reduction Program (HHRP+) or to an active control that included harm reduction components recommended by the National AIDS Demonstration Research Project. The treatment phase lasted 6 months, with follow-ups at 6 and 9 months after treatment entry. Patients in both treatments showed reductions in risk behaviors. However, patients assigned to HHRP+ were less likely to use illicit opiates and were more likely to adhere to antiretroviral medications during treatment; at follow-up, they had lower addiction severity scores and were less likely to have engaged in high risk behavior. Findings suggest that enhancing methadone maintenance with an intervention targeting HIV-seropositive IDUs increases both harm reduction and health promotion behaviors.
