Hyperactive and comparison boys participated in 5-week summer enrichment programs that included classroom activities and structured assessments of peer interaction patterns. During the 3rd and 4th weeks of these programs, a double-blind, methylphenidate-placebo crossover design was implemented within the hyperactive group. Three heterogeneous indicators of everyday behaviors were obtained: number of negative incidents noted by staff, quality of handwriting, and number of times the teacher called the boys' names aloud in the classroom. Medication effects emerged for each of these indicators. When hyperactive boys were taking placebos, they were involved in more negative incidents, their handwriting was poorer, and their names were called more frequently than when the boys were taking methylphenidate. Interrelationships among the measures suggest moderate cross-situational generality of medication responsiveness. Discussion focused on the bandwidth of medication effects and the need to examine the social ramifications of child treatments.This research was supported in part by NIMH grant 29475 and NIDA grant 01070. We gratefully acknowledge the participation of the data coders and the many summer school staff. Special thanks go to Mike Berlin, Barry E. Collins, and Sharon Dotemoto. Methylphenidate and placebo were supplied by Ciba-Geigy, Summit, New Jersey. 相似文献

The effects of valence of alternatives, choice, and expected delay of choice consequences on postdecision evaluations of choice alternatives were studied by either giving subjects a choice between two experimental tasks (both either pleasant or unpleasant) or assigning subjects their initially preferred task. Crosscutting valence and choice, subjects expected either no delay, 10-min delay, or 30-min delay before engaging in the task. All subjects evaluated both tasks immediately after the delay instructions but before experiencing the actual delay. Results confirmed the expected dissonance effect; that is, an upward evaluation of the chosen alternative and a downward evaluation of the rejected alternative, relative to no-choice conditions. Moreover, the relative upward evaluation of the chosen alternative increased as the expected delay decreased. Valence was not found to interact with other variables. The results are discussed in terms of differential salience of choice alternatives. 相似文献

Subjects in an exercise training condition participated in a 10-week aerobic exercise class, whereas subjects in waiting-list control and independent control conditions did not. The results indicated that subjects in the training condition evidenced reliably greater improvements in physical fitness (aerobic capacity) and reported reliably greater improvements in their abilities and confidence in both the physical area (e.g., ability to run distances) and nonphysical area (e.g., frustration tolerance) than did subjects in the control conditions. On the other hand, improvements in physical fitness were not related to reported improvements in abilities and confidence. These findings are of interest because they indicate that some of the important personal changes that are associated with physical fitness training are not due to changes in fitness, but appear to be due to other factors (e.g., group participation and expectancies). 相似文献

The psychometric properties of the Personal Attributes Questionnaire were examined in independent samples of male and female high school students, college students, and adults. In each of the six samples a two-factor structure (masculinity/instrumentality and femininity/expressivity) paralleling the empirically derived scales was found. Additional factor analyses of negative masculine and feminine traits were reported. Discriminant analyses revealed highly significant differentiation between the sexes. The reliabilities (Cronbach alpha) of the unit-weighted scales in each sample were also satisfactory.Support for this research was provided by NASA Grant NSG 2065 (Robert L. Helmreich, Principal Investigator) and NSF Grant BNS 78-08911 (Janet T. Spence and Robert L. Helmreich, Principal Investigators). The article was prepared while the second author was a Fellow at the Center for Advanced Study in the Behavioral Sciences, with support from the Spencer Foundation, NIMH Grant 5T32MH14581-03, and the University of Texas Research Institute. 相似文献

Social problem-solving programs for withdrawn and hyperactive children within a school context were developed and implemented in a day care center, a Montessori nursery school, a Catholic elementary school, and a Catholic high school. This article describes the program implementation for each of the four schools and some of the effects on the consultative relationship. 相似文献

In this century both the literature and social programs devoted to adolescent pregnancy have focused almost exclusively on the female. This article presents a profile of teenage fathers by reviewing the scant literature that is available. The authors make specific recommendations for counselors on the basis of this review. 相似文献
