Auditory-visual interactions in the perception of a ball's path

We carried out two experiments to measure the combined perceptual effect of visual and auditory information on the perception of a moving object's trajectory. All visual stimuli consisted of a perspective rendering of a ball moving in a three-dimensional box. Each video was paired with one of three sound conditions: silence, the sound of a ball rolling, or the sound of a ball hitting the ground. We found that the sound condition influenced whether observers were more likely to perceive the ball as rolling back in depth on the floor of the box or jumping in the frontal plane. In a second experiment we found further evidence that the reported shift in path perception reflects perceptual experience rather than a deliberate decision process. Instead of directly judging the ball's path, observers judged the ball's speed. Speed is an indirect measure of the perceived path because, as a result of the geometry of the box and the viewing angle, a rolling ball would travel a greater distance than a jumping ball in the same time interval. Observers did judge a ball paired with a rolling sound as faster than a ball paired with a jumping sound. This auditory-visual interaction provides an example of a unitary percept arising from multisensory input.     

Implicit romantic fantasies and women's interest in personal power: a glass slipper effect?

Three experiments investigated the relationship between women's romantic fantasies and their interest in personal power. Romantic fantasies (associating partners with chivalry and heroism) were assessed using the Implicit Association Test and self-reports. In each experiment, women's implicit romantic fantasies were dissociated with their conscious beliefs. More important, implicit (but not explicit) romantic fantasies negatively predicted women's interest in personal power, including projected income, education goal, interest in high-status jobs, and group leadership appeal. By contrast, men's implicit romantic fantasies were not routinely linked to their interest in personal power. In concert, the findings are consistent with positing a "glass slipper" effect for women that may be an implicit barrier to gender equity.     

Discrimination and Puerto Rican children's and adolescents' mental health

Two studies of Puerto Rican youths' development on the U.S. mainland examined the consequences of perceived racial/ethnic discrimination on mental health. In Study I, children were found to have a low likelihood of perceiving discrimination, whereas in Study 2, nearly half of the adolescent sample reported perceiving racial/ethnic discrimination. Although both groups scored high on multiple indicators of mental health, perceiving discrimination and worrying about discrimination were negatively associated with some dimensions of self-esteem and positively associated with depression and stress. Adolescents were aware of negative stereotypes about Puerto Ricans, and nearly half of them related discriminatory instances. Results suggest that both perceiving discrimination and anxiety regarding discrimination can serve as risk factors for the mental health of this population.     

An Integrative Brief Treatment Approach for Obsessive-Compulsive Disorder

This article reports on the integrated application of cognitive therapy, transactional analysis techniques, and the behavioral technique of response prevention using self-instructional training and behavioral substitution in a brief therapy approach. These methods were applied in the case of a young man who presented with compulsions to perform repetitive and ordering rituals with the belief that it would prevent his girlfriend from becoming pregnant. A 21-year-old white male who had performed 3 to 5 hours of rituals daily for several years was able to eliminate the majority of his compulsive behaviors and reduce his level of anxiety after eight clinical therapy sessions. Results were maintained at 6-month follow-up. The clear precipitating factors and the unusual maintaining variables for the disorder in the client are described. The author discusses the case in light of current theoretical, therapeutic, and biomedical understandings of the disorder.     

Two investigations of “female modesty” in achievement situations

Two experiments examined motivations underlying the common finding that females present themselves more modestly than males in achievement situations. In Study 1, 388 first-year college students, primarily European-Americans, predicted their first semester grade point averages (GPAs) in one of 3 public and 2 private conditions, which varied the salience of modesty concerns and/or concerns about the others' feelings. In the public conditions combined, but not in the private conditions, women's predictions were lower than men's, although there were no gender differences in actual GPA. The public condition in which the others' feelings and modesty concerns were made salient accounted for this difference between men and women. In Study 2, 230 first-year college students predicted their first-semester GPAs in private, in public to a “nonvulnerable” other, or in public to a “vulnerable” other (someone who supposedly had earned a low GPA). Women's estimates were lower than men's in the latter condition only and lower than their estimates in the other conditions. These results suggest that relational motivations, rather than a simple lack of self-confidence or modesty alone, are a factor in gender differences in self-presentation of achievement.     

Union Influence on Internal Organizational Decisions: An Empirical Analysis

The development of appropriate models of organizational decision making requires a complete determination of the different groups that affect the decision-making process. The present investigation examines the influence of union officials as a group on internal organizational decisions. The rank and file membership of three local unions ( N = 1324) and their first level supervisors ( N = 205) were surveyed regarding the perceived influence of five different groups within the organizational hierarchy. A methodology developed by Tannenbaum (1968) and his associates was modified to include lower-level union representatives as one of five groups who potentially wield influence over organizational decisions. The results of this investigation determined that union representatives are seen as possessing significant levels of influence regarding microlevel organizational decisions. Additional analyses revealed that first-level supervisors believed that union representatives possessed more influence in organizational decisions than they possessed as a group. The implications of these findings and suggestions for future research are discussed.     

ALTERING SHOPPERS' SUPERMARKET PURCHASES TO FIT NUTRITIONAL GUIDELINES: AN INTERACTIVE INFORMATION SYSTEM

This study reports the results of one effort to help supermarket shoppers alter food purchases to make purchases (and meals) that are lower in fat and higher in fiber. A prototype interactive information system using instructional video programs, feedback on purchases with specific goals for change, weekly programs, and the ability to track user interactions and intended purchases was evaluated. The major dependent measure was users' actual food purchases as derived from participants' highly detailed supermarket receipts. After a 5- to 7-week baseline phase, participants were randomly assigned to an experimental or control condition for the 7- to 8-week intervention phase. A follow-up phase began 5 to 8 weeks after participants completed the intervention and discontinued use of the system. The results indicated that experimental participants, when compared to control participants, decreased high fat purchases and increased high fiber purchases during intervention, with evidence for some maintenance of effect in follow-up. Plans for increasing the use and impact of the system are discussed.     

Who enrolls in prevention trials? Discordance in perception of risk by professionals and participants

Internal and external validity problems permeate all intervention studies but are accentuated in primary preventive intervention research, particularly when studies target or recruit individuals based on their risk for psychopathology. Since many people who are at risk do not yet experience distress, they may not perceive the need for intervention. Recruitment tactics based on explaining extent of risk are unlikely to be persuasive and may have negative consequences. If respondents are not motivated to participate, a small or biased subset of the target population will participate in the intervention. Bias is of special concern when those enrolled represent only part of the continuum of risk. Selective enrollment may compromise both internal validity (the interpretation of the research results) and external validity (the generalizability of the findings) of intervention trials in primary prevention. This article discusses the effects of partial enrollment and the resultant bias. It suggests several strategies for increasing the enrollment of the target population and examines some of their ethical ramifications. It also stresses the importance of collecting systematic data documenting how the participants in the intervention differ from the target group as a whole.
