Sixty undergraduate males participated in an experiment with a 2 × 3 factorial design involving two levels of density and three levels of noise to demonstrate effects of the independent variables (density, noise) on cognitive task performance and affect. As predicted, it was found that crowding and noise lead to deterioration of subject's performance on cognitively complex tasks but not on simple (cognitive) task. Also, density and noise generated a negative feeling in the subjects. Significant two-way interaction for complex task, showed variation in performance of Ss of high and low density under low and high noise conditions. In addition, crowded-condition subjects reported more dissatisfaction about their performance and evaluated the presence of the experimenter as significantly less pleasant than their noncrowded-condition counterparts. 相似文献

Sixty male and 60 female subjects previously classified as high and low on a residential crowding experience scale participated in an experiment involving a 2 × 3 × 2 × 2 (density, noise, crowding experience, gender) factorial design. The research was undertaken primarily to determine the influence of previous residential crowding experience as tapped by the Crowding Experience Scale (CES) on reactivity to the environmental stressors of noise and crowding. The results indicated that exposure to environmental stressors produced a deleterious effect on complex task performance and generated negative affect in the respondents. Interestingly, respondents who had reported high levels of experience with crowding showed relatively more crowding tolerance by performing significantly better on cognitively complex tasks (complex anagrams and story comprehension) and exhibiting more positive affect in conditions of high density as compared to low experience of crowding respondents. Reactions to noise were not influenced by crowding experience. Thus, prior experience of crowding as measured by the CES appears to influence reactivity to density in other settings. 相似文献

Two test statistics are proposed for testing the equality of two correlated proportions when some observations are missing
on both responses. The performance of these tests in terms of size and power is compared with other tests by means of Monte
Carlo simulations. The proposed tests are easily computed and compare favorably with other tests. 相似文献

Sri Lanka has the one of highest rates of suicide. Important factors associated with suicide were determined via the psychological autopsy approach (which had not been carried out previously in Sri Lanka). Over a 3-month period, in a catchment area, 31 suicides among Sinhalese were identified and 27 were investigated. Males were more likely to commit suicide and alcohol abuse and domestic violence were reported as contributory factors. We found it possible to use psychological autopsy methods to obtain information which can inform planned prevention measures. 相似文献

This randomized clinical trial with a sample of adults (N = 129) from India explored the effects of a single core‐transformation session on symptom experience and psychological growth. The results over the total 8‐week study period indicated significant, moderate overall effect sizes (ds = 0.63 and 0.52) for symptom experience, emotional stability, affect balance, global well‐being, and purpose in life. Implications for research and clinical practice are discussed. 相似文献
