Dynamic role of social support in the link between chronic stress and psychological distress. 总被引:3,自引:0,他引:3
How a chronic environmental stressor can interfere with the buffering effects of social support by eroding social support was analyzed in this prospective, longitudinal study. A classic buffering effect of support was found after 2 months of exposure to the stressor, household crowding. Crowded residents with low perceived support had greater increases in psychological distress than did crowded residents with high perceived support. However, after 8 months exposure the buffering effect disappeared. Moreover, greater crowding had become directly associated with lower support, which in turn was associated with greater increases in psychological distress. All analyses controlled for prior distress. Under some types of chronic stress, the buffering effects of social support may be short-lived because the stressor eventually erodes social support. 相似文献

This study was done to examine the relationship between sex and perception of body image among athletes and nonathletes. A total of 211 men and women athletes and nonathletes completed a questionnaire which asked them to identify from a nine-figure body-silhouette scale their current image and the image that they thought was most ideal. t tests showed no significant differences for men based upon athletic participation and that both athletes and nonathletes were satisfied with their body image. However, when comparing current image and ideal image, significant differences were found for women athletes and nonathletes. These data support previous research documenting women's dissatisfaction with their body images and show athletic participation is not associated with this perception. 相似文献

Tactile attention and the perception of moving tactile stimuli 总被引:3,自引:0,他引:3
Three experiments investigated the ability of subjects to identify the direction of movement of a pattern across the skin. In Experiments 1 and 2, subjects were required to identify the direction of movement of a pattern presented to one fingerpad while another moving pattern was being presented to an adjacent fingerpad. Subjects were instructed to attend only to the target location. The results showed that accuracy was consistently higher and reaction times were consistently faster when the two patterns moved in the same direction than when they moved in opposite directions. Both effects were largest when the two patterns were presented simultaneously. In Experiment 3, the nontarget location was the contralateral hand. In this case, performance was not affected by the presentation of the nontarget. Combined, the results suggest that movement information is processed across adjacent fingers even when subjects are explicitly instructed to attend only to one finger. Subjects do appear to be able to restrict attention to a single hand. 相似文献

Problem-oriented training promotes spontaneous analogical transfer: Memory-oriented training promotes memory for training 总被引:3,自引:0,他引:3
Spontaneous analogical transfer is the use of information from one problem to solve another problem, without an explicit hint to use the previous information. The results of five experiments were that if subjects tried to solve a training problem before hearing its solution, or tried to explain a training story's solution before hearing the correct explanation, spontaneous transfer was more likely than it was if subjects had studied the same training passage for memory before hearing its solution or explanation. The advantage of problem-oriented processing over memory-oriented processing occurred even though solution attempts nearly always failed, and the advantage was not reduced if the target problem was tested 15 min later rather than immediately after training. We propose that problem-oriented processes performed at study are appropriate processes to use at test. Further support for the account comes from subjects' memory for the training passages; the advantage for problem-oriented processing on solution tasks was mirrored by an equally substantial advantage for the memory-oriented subjects on a recall task. 相似文献

Two response measures that described the consistency and accuracy of motor performance were investigated. A pursuit tracking task was used as the vehicle whereby changes in perceptual motor performance could be monitored over several learning trials. The intra-individual variability of a subject's tracking response was compared to the root mean squared error that was accumulated during each block of trials. Whereas both response measures were sensitive to the changes in performance that occured as a result of practice, neither could be considered sufficiently informative as to be used as a sole indicator of skill acquisition. It appears that both consistency and error measures are needed to describe the subjects' performance as they acquire a perceptual motor skill. 相似文献

College subjects undertook nine cognitive tasks with different perceived sex linkages, stating their expectancy of success prior to each task and attributing causality for their perceived performance following each task. As hypothesized, two components were present in the overall sex difference in expectancy of success, even when differences in actual task performance were statistically controlled. One component was attributable to a general tendency of females to state lower expectancies; the other was a function of the accord between the perceived sex linkage of the task and the subject's sex. The attribution data suggest that females tend to be more external for success and more internal for failure than males.The research reported here was partially supported by Grant #10692 from the Research Foundation of the City University of New York.

The concept of ‘personal space’ has sometimes been invoked in attempts to explain stressful effects of crowding; but the literature
on personal space reveals divergent findings according to the definitions and methods of measurement used. Redefinitions are
proposed whereby personal space preferences can be seen as mediating our reactions to the spatial proximity of others, according
to a dynamic model which considers both task-related needs for physical space and privacy needs, together with concern over
social norms and attributions.
It is argued that perceived illegitimate invasion of the personal space one claims is likely to give rise to stress effects
if coping responses fail. Thus crowding is likely to be stressful in many natural contexts where personal space is intruded
upon frequently, especially when attributions of intentional thwarting are made. Further theoretical advances in this area
must rest upon more precise specification of processes by which social relationships, situational variables, and subjective
motivational, perceptual, and evaluative factors jointly determine an agent’s personal space claims and associated reactions
to spatial invasion. 相似文献

Two experiments were carried out to investigate whether visual imagery was used in representing transitive linear ordering relationships. Subjects were presented with passages describing either a linear ordering or a set inclusion relationship, while being subjected to either visual or verbal interference. Performance was tested by asking subjects to judge the truth or falsity of statements concerning both the information presented in the passages and inferences that could be drawn from this information. In neither experiment was there any evidence for the linear ordering material being selectively disrupted by the visual interference task, as would have been predicted by the imagery theory. Thus it is concluded that linear orderings are probably not represented as visual images. 相似文献
