This study examined the effect of prior biofeedback-assisted training of hand warming or hand cooling on the subsequent ability to train the opposite response. A two-group crossover design employed 43 subjects with one group receiving three days of hand warming followed by three days of hand cooling, while the second group received the opposite sequence. Analysis indicated subjects were able to produce the appropriate changes in hand temperature and were more successful at hand cooling than hand warming. During the transfer of training phase, subjects with prior training in hand cooling were able to produce warming above baseline levels compared with subjects initially trained to hand warm. In contrast, prior training of hand warming had no effect on the subsequent ability to cool hands. 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

A study of 79 female college students examined the reliability and validity of two new size/weight-related measures of body image. The Body-size Appraisal Scale and the Overweight Preoccupation Scale were derived from existing instruments. Analyses supported the internal consistency and 2-wk. test-retest reliability of both new scales. Correlations of scores on each scale with measures of anxiety about being fat, negative body-image affect and avoidance, restrained and bulimic eating, and depression support their concurrent and construct validity. Scores on the Overweight Preoccupation Scale were also related to the extent of investment in physical appearance. Regression analyses indicated that each new scale could be predicted from several other conceptually relevant body-image attitudes, even after actual body weight was controlled. 相似文献

The aim of this study was to investigate the possible relations between specific personality variables and the effect of subliminal stimulation on choice behavior. It was hypothesized that subjects with low anxiety, less neuroticism, and external locus of control and the trait of extraversion would be more susceptible to subliminal stimulation. 38 undergraduate students were exposed to subliminal messages urging them to choose symbols instead of numbers or letters. Analysis showed that subliminal stimulation did not generate a preference for symbols over numbers or letters. No support was observed for the hypothesis of an association between susceptibility and personality variables. These results may be explained in terms of symbol choice being a neutral message that did not relate to the subjects' needs and motivation. 相似文献

32 right-handed, learning disabled children aged 8-10 yr., 11-13 yr., and 14-16 yr. were presented a tactile discrimination task. Pairs of fabrics of different or the same texture were presented to the same hand (uncrossed condition) or alternating hands (crossed condition). Discrimination errors were compared using a verbal response mode and a nonverbal response mode. Analysis indicated that the number of crossed errors was significantly greater in the verbal response mode than in the nonverbal response mode for only the youngest children. These results suggest selective attention-activation bias and/or hemispheric processing limitations for younger learning disabled children. 相似文献

Effects of media violence on viewers' aggression in unconstrained social interaction 总被引:4,自引:0,他引:4
This article provides a meta-analytic review of the experimental effects of media violence on viewers' aggression in unstructured social interaction. In the reviewed experiments, children or adolescents were exposed to violent or control presentations and their postexposure behavior was coded for aggression during spontaneous social interaction. Exposure to media violence significantly enhanced viewers' aggressive behavior when the findings were aggregated across studies, but the effect was not uniform across investigations. Only suggestive evidence was obtained concerning moderators of the effect: Marginally stronger relations were obtained in those studies using a cross-section of the normal population of children (vs. emotionally disturbed children) and in those studies conducted in laboratory settings (vs. other contexts). 相似文献

Neuropsychological correlates of hypertension: review and methodologic considerations. 总被引:5,自引:0,他引:5
Essential hypertension is a chronic disorder having many potential physical and behavioral sequelae. This article evaluates the impact of hypertension on neuropsychological test performance. First, cross-sectional and longitudinal studies that examine the neuropsychological correlates of hypertension are reviewed. In general, hypertensives are found to perform more poorly than normotensives, particularly on tests of memory, attention, and abstract reasoning, and less consistently on tests of perception, constructional ability, mental flexibility, and psychomotor speed. Next, the influence of variables that may moderate relationships between hypertension and neuropsychological performance--such as age, education, and medication usage--are examined. Finally, potential mechanisms, both physiological and psychological, underlying associations between hypertension and neuropsychological performance are discussed. 相似文献

Videocassettes have become the dominant medium for pornography. One previous content analysis examined the prevalence of violence in such videos. The Attorney General's Commission on Pornography (1986) has asserted that nonviolent pornography depicting degradation produces harm similar to that from violent pornography. Content analysis of a 10% random sample (n = 50) of the videos displayed in the "adult" section of a video store showed that 13.6% of the scenes in the videos contained violent acts and 18.2% contained degrading acts. 相似文献

This study examined three factors affecting college students' attributions of blame for an AIDS patient's disease: sexual orientation of the patient, mode of HIV transmission, and the sex of the subject. 148 subjects read one of six vignettes describing an hypothetical AIDS patient who was described as either an heterosexual or an homosexual man who contracted HIV through one of three avenues: blood transfusion, sexual contact, or IV drug use. The homosexual AIDS patient was considered more to blame for his illness than the heterosexual AIDS patient, but only when mode of transmission was sexual contact. In addition, mode of HIV transmission was a significant factor in attributions of responsibility, as the patient who contracted HIV through a blood transfusion was rated as less responsible than the patient who contracted HIV through sexual behavior or IV drug use. Women consistently rated the AIDS patient as less responsible than did men. 相似文献
