Two expriments were conducted to test implications derived from Lerner's formulation of the “justice motive.” The experimental paradigm provided subjects with an opportunity to earn money in exchange for participation in future experimental sessions. Subjects who were offered “just” pay for their efforts volunteered significantly more of their time when their efforts would help a needy victim than when they would not. Moreover, when subjects were left with just pay, they offered more of their time when a portion of their pay was to go to a victim than when they received the entire wage themselves. When the pay subjects were to receive was less than deserved, however, the opportunity to help a victim did not affect their response level. The importance of these results for understanding helping behavior is considered, as is the compatibility of these results with other theoretical models.  相似文献

Interhemispheric alpha activity was measured while subjects were engaged in covertly imaging familiar pictorial material using three imagery modes: “shapes and colors,” “words,” or both. The results showed suppression of alpha activity in the hemisphere which is primarily involved in the cognitive mode being used by the subject.  相似文献

The way subjects remember a list of two-digit numbers has been examined in some detail. It is found that intrusions in free recall are not random. They resemble omissions in having the same first digit but not in other ways. This non-randomness of recall errors has been used to construct recognition tests of varying difficulty. Numbers which occurred commonly as intrusions were difficult to distinguish from the correct items when used as distractors in recognition tests. The experiments suggest that the previously observed relationship between recognition efficiency and number of alternatives (Davis, Sutherland and Judd, 1961) can be attributed to the increased probability that such intrusions will be included when the total number of distractors is increased.  相似文献

Dynamic effects of food magnitude on interim-terminal interaction   总被引:3,自引:3,他引:0       下载免费PDF全文
We tested the assumption of a facilitatory relation between periodic food presentation and schedule-induced drinking by examination of (a) elicited drinking, (b) drinking in anticipation of food delivery, and (c) possible indirect effects of food delivery on drinking. We exposed rats to a fixed-time 60-second schedule in which interfood intervals ended in either one or four food pellets with equal probability. In Phases 1 and 3, a stimulus signaled the magnitude of upcoming food presentation. In Phase 2, the stimulus was eliminated. Changes in drinking and “head-in-feeder” distributions within interfood intervals demonstrated that head-in-feeder was controlled directly by food presentation, but drinking was not. Head-in-feeder increased and drinking was reduced when large meals began or ended an interval. In Phases 4 to 6, meal size was manipulated across sessions yielding a positive relation between meal size and schedule-induced drinking. We conclude: (1) Schedule-induced drinking is determined by distributions of food-related behavior and results from indirect effects of food delivery; and (2) the amount of schedule-induced drinking and the form of the drinking distributions in this experiment can be accurately explained by two assumptions: (a) Food presentation facilitates food-related behavior through elicitation and anticipation; and (b) food-related behavior and drinking are reciprocally, linearly related.  相似文献

Abusing and high-risk families have been seen over three years at a new treatment resource with a family therapy orientation. The families present with established resistance to any treatment intervention and many have defeated a succession of previous helping agencies. Initial typology and treatment strategies are described with the aim of more systematic selection of therapeutic techniques.  相似文献

This study examined the effects of communication, feedback, and identifiability on behavior in a simulated commons. To do this, 64 mixed-sex groups of four introductory psychology students participated in a commons dilemma simulation for 50 trials or until the group exhausted the commons pool. Half of the groups played under a free communication condition, while the other half were prohibited from communicating. Half of the groups in both communication conditions received visual feedback about the amount of the commons' resource (money) which remained after each trial while the other half received no feedback. Finally, half of the groups in each of these four conditions were made highly identifiable by the use of the name tags and feedback about the choices of each player. The remaining groups were assigned to a low identifiability condition in which no name tags were used, no feedback given and group members were separated by wooden dividers to prevent visual contact. Results showed that groups having the opportunity for resource feedback or for communication achieved greater total money harvests and maintained the commons for a greater number of trials than groups having neither. As expected, the largest totals and longest commons maintenance were achieved by groups having both. Identifiability had no influence on the length of commons maintenance except when there was neither resource feedback nor communication opportunities. When both were unavailable, groups in the high identifiability condition harvested more money and maintained the commons longer.  相似文献

Family resilience is a relatively new construct that describes how families adapt to stress and bounce back from adversity. Literature pertaining to resilience as a family-level variable is reviewed. An overview of the developmental psychopathology literature dealing with individual resilience is also presented. Implications for extending the study of family resilience drawn from research on individual resilience are discussed and a definition of family resilience is proposed.  相似文献

The need to establish guidelines for total quality management in genetic counseling is now recognized as new genetic technologies are being introduced into genetics services and primary care. Genetic counselors have an important role in developing methods for assuring quality in the genetic counseling process. Emerging quality improvement measures as well as selected examples from the Quality Assurance Program in the Genetics Services Division at the Foundation for Blood Research are presented as examples of direct genetic counselor involvement. Suggestions for future directions of quality improvement activities for genetic counselors are discussed.  相似文献

Advances in DNA technology are leading to major developments in nursing practice in clinical genetics, including the creation of new roles for nurses who care for people with genetic conditions. Application of genetic information and testing is moving genetics into the mainstream of health care. Therefore, it is anticipated that nurses in all areas of practice will become involved in the provision of information about genetic testing and assisting individuals and families in decision making and adjustment to new genetic information. This article provides an overview of the profession of nursing which may be useful to genetic counselors in the development of collaborative relationships between the two professions.  相似文献
