A Situational Model of Sexual Assault Prevention through Bystander Intervention

Bystander intervention is a potentially potent tool in the primary prevention of sexual assault but more information is needed to guide prevention programs (Banyard 2008). Undergraduates (378 women and 210 men, primarily White) at a central coast California university completed an anonymous questionnaire measuring five barriers identified by the situational model of bystander intervention (Latane and Darley 1970) and bystander intervention behavior. As expected, the barriers were negatively correlated with intervention, were greater for men than for women, and intervention likelihood was affected by perceptions of victim worthiness, especially for men. Hypotheses predicting a positive relationship between having a relationship with the potential victim or perpetrator and intervention were supported. Implications for sexual assault bystander intervention programming are provided.     

Spatial cognition in the gerbil: computing optimal escape routes from visual threats

Previous studies in our laboratory have shown that when presented with a sudden stimulus simulating an oncoming predator, Mongolian gerbils can compute the optimal trajectory to a safe refuge, taking into account the position of the threat, the location of a clearly visible refuge, and several other contextual variables as well. In the present studies, the main goal was to explore the abilities of gerbils to use mental representations of spaces that were visually occluded by opaque barriers to compute efficient escape trajectories. In all studies, gerbils were placed into a round open field containing a single refuge. On each trial, an overhead visual stimulus was caused to ‘fly’ overhead, eliciting robust escape movements from the gerbils. By manipulating the shape and position of a series of opaque barriers that were interposed between the gerbils and the refuge, we were able to show that gerbils can compute the shortest route to an invisible target, even when the available routes to the target are made complex by using elaborate barrier shapes. These findings suggest that gerbils can maintain representations of their locations with respect to salient environmental landmarks and refuges, even when such locations are not continuously visible.     

Compelled authorizations for disclosure of health records: magnitude and implications

Each year individuals are required to execute millions of authorizations for the release of their health records as a condition of employment, applying for various types of insurance, and submitting claims for benefits. Generally, there are no restrictions on the scope of information released pursuant to these compelled authorizations, and the development of a nationwide system of interoperable electronic health records will increase the amount of health information released. After quantifying the extent of these disclosures, this article discusses why it is important to limit disclosures of health information for nonmedical purposes as well as how it may be possible to do so.     

Increasing Community Recycling with Persuasive Communication and Public Commitment

Persuasive communication and public commitment were used to encourage recycling in a citywide program. The persuasive communication was a combination of factors which have been found by laboratory researchers to produce attitude and/or behavior change. The public commitment manipulation involved signing a statement supportive of recycling. Households which did not recycle during a 6-week baseline period were selected for experimental study. Trained Boy Scouts made an oral informational statement and then gave each of 201 experimental households one of three treatments (a written persuasive communication, public commitment, or both). A control group of 132 homes received no treatment. Recycling was observed for 6 weeks following delivery of all treatments. Results indicated that the three treatment groups recycled significantly more than the control group but did not differ significantly from each other. Future directions for applied work in this domain are discussed.     

Divergent perceptions of lesbians: a comparison of lesbian self-perceptions and heterosexual perceptions.

Social-psychological research on stereotyping was applied to lesbianism among American college students. The hypothesis that stereotypes of lesbians are often inaccurate predictors of individual lesbians was supported. Using stereotypes of lesbians identified by previous research, lesbians rated themselves on a series of bipolar stereotypical adjectives, and a comparison group of nonlesbians rated lesbians as a group on these same adjectives. Significant differences were found on 16 of the 21 adjectives. Knowing a lesbian personally did not influence heterosexuals' ratings, suggesting the resistance of stereotypes to change.     

The effects of choice-making on the problem behaviors of high school students with intellectual disabilities

This investigation was conducted in an effort to systematically extend the emerging data base having to do with choice-making opportunities and the behavior of students with disabilities. In particular, the current analyses examined the effects of choice-making on the problem behavior and task engagement of three high school students with intellectual disabilities as the students performed domestic and vocational activities. Multiple baseline and reversal designs demonstrated that the choice conditions reduced problem behaviors and increased task engagement for all participants. Data having to do with student affect and task productivity were less consistent. The findings on the relationship between choice making and problem behavior replicate and extend a growing literature on the desirable effects of choice-making for individuals with disabilities. The results are discussed in terms of recent developments in behavioral support, as well as the need for ongoing conceptual and applied research.     

Childhood tomboyism and adult androgyny

Female university and community college students (N =194) completed the Bem Sex-Role Inventory and a 12-item tomboyism index. Subjects were predominantly Euro-American (71%). A multiple regression analysis was used to test the prediction that androgyny and masculinity would significantly predict tomboyism scores. The proportion of variance in tomboyism accounted for by masculinity was significant, but once masculinity was entered, no additional predictive value was added by the entry of androgyny or femininity. Tomboyism was not related to the development of expressive qualities such as compassion and sensitivity to the needs of others. However, tomboyism was positively related to some desirable instrumental qualities such as assertiveness and self-reliance. Tomboyism was common and generally declined at puberty due to social pressure.
