The two studies undertaken investigated how reaction times are affected by preknowledge concerning hand and direction parameters, and the order in which these data are disclosed. In the first experiment, preknowledge was manipulated by selecting 2-CRT pairs which had either a common hand or direction component. Reaction signal information content (as defined by the number of unknown response parameters) was controlled, but no parameter differences emerged. When parameter order was manipulated by sequential precuing, the ‘hand then direction’ order conferred a significant advantage. Motor preparation and response selection explanations for this effect are considered. Various difficulties with the paradigms used are discussed, including those of distinguishing between response selection and motor programming contributions, controlling and inferring the strategies adopted by subjects, and defining task difficulty. The prospects for independently fostering either response identification or motor preparation by means of an appropriate selection of precues are also discussed. 相似文献

Family-centered, community-based, coordinated care for children with special needs is presented as the best practice model for providing services to children and families. Psychologists must learn to play an active role in this frame-work that both integrates psychology with other health and education disciplines and uses the broad spectrum of psychological knowledge about families, development, community organization, and intervention strategies. Key principles of family-centered child psychology affect practice research and training. The psychologist becomes part of a team created to support families as the primary care-givers of their children. Training programs must reorganize the types of experiences both in the classroom and the field to train new psychologists within this model. As mandates for family-centered care affect policies at the state and federal levels, research will remain a critical factor in understanding the effects of these policy shifts on child and family functioning and the delivery of services. 相似文献

The Effects of Procedures, Social Accounts, and Benefits Level on Victims' Layoff Reactions 总被引:1,自引:0,他引:1
Three hundred and fifty-three layoff victims responded to questions describing their reactions to layoffs. Victims also described management layoff practices. Two measures of procedural fairness in layoff practices (decision-making characteristics and social accounts) and one measure of layoff outcomes (benefits level) were included. Only decision-making characteristics predicted exemployee willingness to recruit for a former employer and desire for regulation of layoffs. These results provide further evidence of the importance of procedural justice in organizational decision-making. 相似文献

ABSTRACT In this study we examined 15 personality and demographic differences between psychology students who took part in experiments at different times of the semester and different times of the day. In general, few significant relations were found and those that did emerge were small in magnitude. Females and freshmen signed up for experiments earlier in the semester. Females took part in their first experiment earlier in the semester, as did students who were Protestant and who came from smaller home towns. Students low in self-consciousness also tended to begin participating earlier. Extraverts participated earlier in the day than introverts. Results generally were consistent with previous findings of differences between research volunteers and non-volunteers. However, it was concluded that because of their small magnitude and inconsistency from site to site, with a few precautions experimenters probably need not be concerned that timing effects threaten the external validity of psychological research outcomes. 相似文献

This article reviews evidence for a gender difference in responsiveness to others' evaluations in achievement situations. Studies show that women's self-evaluations are more responsive to the valence of the evaluative feedback they receive than are men's. A number of possible explanations for this effect are then discussed, with the best evidence pointing to men's and women's differing construals of the informational value of others' evaluations in such situations. Research on the behavioral consequences of women's lower status as well as on children's experiences with evaluative feedback provides potential explanations for this effect. A more proximal explanation, however, lies in men's and women's different approaches to evaluative achievement situations. Men may be particularly likely to respond to the competitive nature of evaluative achievement and hence to adopt a self-confident approach that leads them to deny the informational value of others' evaluations. Women may be particularly likely to approach such situations as opportunities to gain information about their abilities. 相似文献

Somatic complaints in anxious children 总被引:6,自引:0,他引:6

Although stomachaches and headaches are considered characteristic of children with anxiety disorders, there is converging evidence that a broader range of somatic symptoms may be associated with children's expressions of anxiety. The purpose of this study was to determine the prevalence of somatic complaints in anxious children. The results indicated that children with anxiety disorders endorsed the presence of many different somatic complaints, and that contrary to clinical intuition, stomaches and headaches were not among the most commonly reported symptoms. In addition, the anxious children endorsed significantly more somatic complaints when compared to normal controls. Furthermore, the symptom pattern reported by anxious children indicated the presence of both the somatic and cognitive components usually associated with panic attacks, although none of the children met diagnostic criteria for panic disorder. The results are discussed in terms of the contribution of somatic symptoms to the understanding of anxiety disorders in children. 相似文献

We investigated differences between mildly depressed subjects and normal controls in their memory for, and judgments of, another person. All subjects read a story (containing either predominately positive or predominately negative items) under instructions to form an impression of the story target. Subjects later made several judgments about the target and attempted to recall the story. For both the positive and the negative story, depressed subjects produced significantly more negative intrusions (i.e., recalled nonpresented negative items) than did the normal subjects, but they did not recall more negative items correctly than did the normal subjects. Depressed subjects also perceived themselves as more similar to the negative story target than did the normal controls and indicated greater liking for the negative story target than did the normal controls. 相似文献
