The central question at issue was the role of both infant and parent temperament in determining child adjustment at age 4. Within the conceptual framework of the New York Longitudinal Study (NYLS), both infant and parent temperament were assessed. Factor analyses yielded three comparable infant and parent temperament factors: Mood, Energy, and Consistency. Correlations with teacher ratings of child adjustment indicated the most significant relationship to be with the infant girls' Mood factor (comparable to the NYLS high-risk "difficult" infant factor). No infant factors were found to relate to boys' adjustment, while maternal Mood was significant across sexes. Indices of the temperamental similarity within families also revealed sex differences relative to adjustment, with similarity across all family members significantly related to adjustment for girls and boy-father dissimilarity significant for boys. Discussion centered around continuity-discontinuity issues relevant to sex differences.  相似文献

The illusion of control, the tendency for individuals to approach chance tasks with skill-appropriate strategies, was studied. Subjects premeasured on a mania scale were classified as either high (HM) or low (LM) in mania. In the first phase of the study, HM and LM subjects performed 30 trials on either a skill (verbal associates) or chance (coin-toss) task and were given either 20, 50, or 80% success feedback. After Task 1 was completed, subjects filled out an attribution questionnaire. In the final phase of the study, subjects anticipated 30 more trials either on a skill or chance task. Subjects' predicted successes were measured. It was hypothesized that predicted successes on anticipated skill and chance tasks would be affected more by outcomes on a previous skill task than by outcomes on a previous chance task. The results for the anticipated skill task directly supported the hypothesis. On the anticipated chance task, the hypothesis was confirmed for HM subjects only. The results are discussed in terms of how previous skill experiences may induce a set to control ungovernable situations for individuals with manic reactions.  相似文献

From a review of literature and an examination of data from the Counseling Services at the University of Texas - El Paso, the authors conclude that Mexican-American students place more emphasis on cooperation and group achievement than on individual achievement, and that the education of Mexican Americans may be enhanced when teachers properly reinforce “successful behavior.” In addition, it seems that problems may arise in using U.S.-based theories of “democratic” leadership styles because the Mexican-American culture places more emphasis on traditional leadership roles.  相似文献

Critical reading of Bronfenbrenner's Moral Dilemmas Test (MDT) suggests that it measures two basic kinds of moral dimensions: (1) “Negative-passive” moral choices which require the child to resist peer pressure to violate conventional norms in situations fraught with potential adult sanctions, and (2) “Positive-active” moral choices which require performance of an act that affirms a moral principle and implies a benefit for recipients of the act. To test the validity of these distinctions, additional positive-active type dilemmas were constructed to balance the overemphasis on negative-passive situations found in the original MDT. This expanded MDT was then administered to samples of Mormon, Catholic and public school children. Responses from all samples were subjected to factor and cluster analyses and then to a “multitrait-multimethod matrix”. These analyses provide support for the need for making moral sub-distinctions by producing item clusters that are consistently based on the a priori defined negative-passive and positive-active dimensions. A third dimension is also discernable among certain of the original MDT items, but it represents an achievement orientation of only-secondary moral significance. Implications of these conceptual distinctions for linking different kinds of moral responses to different kinds of social contexts are discussed.  相似文献

The present study was undertaken to evaluate the practicability and efficacy of treating enuretic children in residential Children's Homes by means of the enuresis alarm. A control group design was employed with 19 and 20 subjects in the treatment and control groups respectively. Eighteen of the nineteen treatment group children achieved initial arrest of enuresis in a mean of 11.9 weeks of treatment (range 5–28 weeks). Over the initial 12-week period, the treatment group showed a statistically significant reduction in mean wetting frequency, both over time and in comparison with the control group. After a follow-up period of at least 20 months. 17 of the 19 children were known to be dry. The results of an independent evaluation are reported, and it is concluded that alarm treatment is as effective and practicable in Children's Homes as it is in family situations.  相似文献

The techniques of steady visual fixation and repetitious auditory input are used in the laboratory for investigating perceptual phenomena and in yoga and meditation for facilitating altered states of awareness. Phenomena related to mild sensory deprivation are reported in both circumstances.  相似文献
