Use of a virtual reality car-driving stressor in cardiovascular reactivity research

Eighteen subjects (11 males, 7 females) completed a virtual reality car-driving stressor on two occasions several weeks apart. Immediately before and throughout task performance, blood pressure, cardiac output, and total peripheral resistance were assessed. Reactivity scores were calculated for each parameter for each subject as the arithmetic difference between task level and baseline level. The task elicited considerable hemodynamic activation on each occasion of testing, as well as high levels of self-reported task realism, engagement, excitement, and nervousness. Correlation analyses of both absolute and reactivity scores revealed evidence of test-retest reliability. Males were found to exhibit greater absolute levels of and greater increases in systolic blood pressure. The development of tasks suitable for inclusion in a battery of behavioral stressors, responses to which may help identify those at risk for later disease, is of considerable interest in cardiovascular behavioral medicine. The present findings suggest that the virtual reality car-driving task may be useful in this context.

Dichotic listening ear asymmetry: Patterns of longitudinal development

Dichotic listening research with children has continued to be prevalent although numerous authors have described both theoretical and methodological limitations with traditional dichotic listening free-recall paradigms. The present research adds to this growing skepticism by reanalyzing two major longitudinal studies of children's ear asymmetries. These two studies, based in different countries (United States, Holland), utilized highly similar paradigms (free-recall digits), subjects (males), and age levels (kindergarten and second and fifth grade). The questions of ear advantage development, patterns of ear advantages, and the relationship between dichotic listening performance and reading skills are addressed from the multiple statistical methodologies represented in the literature. From these analyses, support for all of the major hypotheses regarding the developmental patterns of dichotic listening performances could be obtained from the same data samples. The use of traditional free-recall dichotic listening paradigms are not recommended for use with children. The implications for future research are discussed.     

The stress of coming out

To conclude, (1) although homosexuality has been recognized for hundreds of years, we still do not understand it completely. (2) This paper places emphasis on the process of individuation and gender-identity that takes place very early in childhood as the cause of homosexuality. (3) If the process is not completed properly, the individual's gender-identity will deviate from that of the vast majority of people. Homosexuality is, therefore, considered by me as a deviation from, rather than a variation of, human sexuality. (4) The degree of neurosis or psychosis associated with homosexuality or heterosexuality is not causal in nature, although the two are intimately intertwined. (5) The stress of coming out varies a great deal in intensity and depends on the degree of integration of the individual and the support given to him by his friends, associates, and family. (6) Although the last decade has brought about a greater acceptance of homosexuality than ever before, sufficient prejudice, ignorance, and fear remain to keep many homosexuals "in the closet." (7) Even today the disclosure of one's homosexuality threatens the individual with the loss of so many important aspects of his life, such as his job, his friends, and even his family, that there is little wonder that coming out of the closet poses such problems for so many homosexuals.     

Job satisfaction among students in work education programs

Data were collected from 1016 students in grades 9–14 from 50 work education programs. Data were also collected from 696 similar students who held part-time jobs but were not participating in work education programs. Participating students were significantly more satisfied with their jobs than were the nonparticipating students. Group atmosphere, availability of adult role models, meaningfulness of work roles, and availability of feedback accounted for much of the variation in job satisfaction among students.
