Reinforcement effects on intrinsic interest: A classroom analog

The potential undermining effects of a reinforcement program were examined in two studies with kindergarten-first grade children. The procedures were designed to provide an analog to typical classroom incentive programs. In one study, the subjects' initial interest in the target activity (coloring) was low, whereas in the other study it was reasonably high. In neither case was an undermining effect evident in follow-up observations.     

Gender and Sex as Determinants of Hireability of Applicants for Gender-Typed Jobs

The effects of gender and sex of applicants for gender-typed jobs were investigated in the context of a simulation of a post-interview decision. Student subjects (N=102) rated eight applicants for one of three gender-typed jobs. Results indicated that, in general, masculine applicants (of both sexes) were preferred over androgynous applicants who were preferred over feminine applicants. For the neutral job, androgynous applicants were preferred over masculine applicants who were preferred over feminine applicants. Male and female students did not differ in their ratings of the applicants. The results were interpreted as indicating raters' preference for masculine characteristics in any job applicant.     

Perfectionism and Sexual Satisfaction in Intimate Relationships

This study sought to provide information on the relations between trait perfectionism and perfectionistic self-presentation and sexual satisfaction in married couples. A sample of 74 married or cohabiting couples were recruited from the community to participate in the study. They completed measures of perfectionism, perfectionistic self-presentation, sexual satisfaction, dyadic adjustment, and depression. The results showed that the interpersonal dimensions of trait perfectionism were negatively related to general sexual satisfaction and sexual satisfaction with the partner for both husbands and wives. After partialing out marital satisfaction and depression, the husband's sexual satisfaction was significantly negatively correlated with his own socially prescribed perfectionism and with his wife's ratings of other-oriented perfectionism. The wife's satisfaction was significantly negatively correlated both with her husband's socially prescribed perfectionism and with her own socially prescribed perfectionism, other-oriented perfectionism, and perfectionistic self-presentation. Regression analyses suggest that the wife's other-oriented perfectionism is a unique predictor of her general lower sexual satisfaction and her husband's lower satisfaction with her contribution to the sexual relationship. Overall, the findings suggest that perfectionistic expectations have an important role to play in sexual satisfaction in married couples.     

Cultural Beliefs About Social Influence Strategies of Mexican Immigrant Women and Their Heterosexual Partners

The present study examined cultural beliefsregarding the use of influence strategies inheterosexual relationships of 40 Mexican immigrantcouples in stable relationships. Although over 75% ofparticipants had completed seven or more years of education,men were more likely to have completed high school thanwomen. Over half the sample (55%) reported familyincomes of $300 or less per week; 23% reported incomes in excess of $400 a week. During a structuredinterview respondents were asked to indicate their levelof agreement on a 4-point Likert scale with 24statements about influence tactics used by women and men in heterosexual relationships. Culturalconsensus analyses revealed a common cultural modelshared by the sample about which strategies men andwomen use to influence their partners. Results suggest that influence strategies are believed similarfor men and women. Direct and indirect strategies areperceived as used by both partners; bilateral strategiesare believed more likely to be used than unilateral strategies. These findings suggest that Mexicanimmigrant women in stable partnerships endorse normsthat support the use of relatively equivalent power inpartner relationships. The use of positive Mexican cultural norms to promote health protectivebehaviors such as condom use and other less risky sexualbehaviors is discussed.     

Inhibition of the Endothelial Isoform of Nitric Oxide Synthase Impairs Long-Term Memory Formation in the Chick

Previous studies with general inhibitors of nitric oxide synthase have yielded variable and contradictory results with respect to their effects on memory. This may have been due to differential effects of blocking the various isoforms of this enzyme. We show that day-old chicks trained on a single-trial passive-avoidance task suffered significant memory loss from ~40 min post-training following post-training intracranial administration of a potent inhibitor of eNOS. Administration of a specific nNOS or iNOS inhibitor at the same time had no effect on retention, although a role for either of these isoforms when administered at a different time after learning has yet to be fully investigated. The onset of memory loss following eNOS inhibition is the same as observed following general NOS inhibition, which suggests that amnestic effects observed in previous studies using nonspecific inhibitors may be attributable to blocking the function of eNOS. The findings indicate that eNOS may play a role in memory formation for this task, which is at least distinct from any role that may be played by nNOS.     

Classroom behavior and children with mental retardation: Comparison of children with and without ADHD

Thirty-four children (ages 6–12 years) with moderate to borderline mental retardation were studied in a laboratory classroom setting to determine whether children identified as having attention deficit hyperactivity disorder on the basis of Conners Questionnaires differed in classroom behavior. Half of the children scored 15 or greater on both the Parent and Teacher Conners; the remaining children scored 11 or less. All were participants in a Saturday Education Program serving children with mental retardation. Direct observation of the laboratory classroom documented significant differences between groups on measures of on-task behavior and fidgetiness, especially during situations where little direct teacher feedback or supervision was available. Saturday Education Program staff, while blind as to group designation, rated the two groups as differing significantly on all scales of two standardized behavior problem checklists. Checklists by parents and teachers appear to be valid measures of classroom behavior of children with moderate to borderline mental retardation.This research was supported by a grant to the first author from the National Institutes of Child Health and Human Development, U.S. Department of Health and Human Services, grant No. 1R29HD26186-01A1.

The role of the hospital in the evolution of elite cultures of medicine

Rosenberg argues that a culture of medicine articulates a unique medical vision reflecting scientific ideologies and perceptions, professional values and rewards, career patterns, and the work context of each generation of physicians (Rosenberg, 1987, p. 7) It might be more accurate, however, to recognize multiple cultures of medicine. This papers traces American hospitals' contributions to three specific aspects of certain elite cultures of medicine. Its first section introduces and explores these aspects transhistorically. They are: a stratified paradigm of the physician-patient relationship, the equation of competence with specialization, and a pattern within a stratified model of medicine called the “Lone Ranger syndrome.” A brief historical profile subsequently highlights changes in the structure and function of American hospitals in the 19th century. The three remaining sections chart the ebb and flow of the prominence and power of these specific aspects of elite cultures of medicine across three historical periods: the late 19th century, 1910–1930, and the post World War II era.
