We examined the effects of acute psychological stress on lymphocyte proliferation and circulating levels of interleukin-1 and -2. Healthy men were exposed to two viewings of a gruesome surgery film and were asked to recall details of the film twice during a 30-min period. These subjects were compared to a nonstress control group. Lymphocyte proliferation to the mitogen concanavalin A (Con A; 5 micrograms/ml) was decreased during and after exposure to the stressor when compared to the control group. This decrease was more pronounced in subjects exhibiting greater blood pressure reactivity while viewing the film than in subjects showing smaller blood pressure responses. None of the other immunological measures was significantly affected by the stressor. Cortisol was not correlated with lymphocyte responsiveness. Possible explanations for these results and implications for further research are discussed.  相似文献

This study examined the effect of high and low communication apprehension in conjunction with social and personal settings upon verbal behavior. Step wise multiple discriminant analysis of the data indicated a linear combination of language indices (number of syllables, Noun-Verb/Adjective-Adverb ratio, and phrase repetitions) which discriminated between the high apprehensive-personal setting group and the remaining three groups. Results are discussed relative to theoretical projections and the potential for sensitivity toward communication behavior being operative within the communication apprehension framework.  相似文献

A comparison of two measures of egocentrism   总被引:1,自引:0,他引:1  
This study examined the relationship between two prominent measures of egocentrism, Enright's Adolescent Egocentrism Scale (AES) and Elkind's Imaginary Audience Scale (IAS), in a sample of 458 adolescents, between 10 and 15 years old. Both correlational and factor analyses indicated that the two measures assess distinctly different phenomena. As predicted, IAS scores were correlated with self-reported levels of shyness, nervousness, and social skills. These results provide partial evidence for the validity of the IAS as a measure of self-consciousness, though not necessarily egocentrism per se. The validity of the AES was not examined.  相似文献

In this study, we examined factors associated with relapse and maintenance following a self-management training course. Thirty-five community professionals participated in a 3-week (30-hr) graduate-level extension course in self-management, which included a self-modification project. Results at a 10-week follow-up showed that end-of-class self-efficacy and outcome expectancy correctly classified over 80% of those who maintained gains in their projects versus those who relapsed. The professionals in the relapsed group also reported significantly more difficulty with anticipated high-risk situations than did those in the maintenance group.  相似文献

In this study, 24 professional writers completed a short pencil-and-paper questionnaire on which they indicated how they felt before, at a pause, and after specific writing episodes. The intensity with which they experienced 20 emotions was assessed, as was the frequency with which these emotions were experienced when writing in general. Results indicated that the professionals experienced positive emotions significantly more often when writing in general than they experienced either negative-active or negative-passive emotions. Negative-passive emotions such as boredom, shame, and shyness were particularly rare and weak. During the actual writing process, positive emotions tended to intensify, whereas negative-passive and negative-active emotions resisted change. Sponsorship of writing had little impact on the quality of emotions experienced during the process. The professional poets, however, experienced negative-active emotions significantly more often when writing in general than did the prose writers.  相似文献
