Depressive self-presentation: beyond self-handicapping 总被引:1,自引:0,他引:1
An experiment was conducted to examine the notion that depressives' responses would reflect a protective self-presentation style (Hill, Weary, & Williams, 1986), the underlying goal of which would be the avoidance of future performance demands and potential losses in self-esteem. In this study, depressed and nondepressed Ss were asked to perform a relatively simple visual-motor task. Half of the depressed and half of the nondepressed Ss were told that if they were successful at the task, they would be asked to perform a 2nd, similar task. The remaining Ss were given no such expectation of future performance. We predicted and found that depressed compared with nondepressed Ss strategically failed at the task when presented with the possibility of future performance and further losses in esteem. Moreover, this strategic failure was associated with some costs; depressed-future performance expectancy Ss experienced more discomfort or negative affect as a result of their performance. The relationship between this depressive self-presentation and self-handicapping strategies is discussed. 相似文献

Gender patterns in social touch: the impact of setting and age 总被引:2,自引:0,他引:2
This study examined the impact of age of participants and the setting in which touch occurred on gender patterns in 799 instances of observed intentional touch. Gender asymmetry, a pattern in which men are more likely to touch women than vice versa, was observed when touch between adults was examined but not when touch involving children was examined. Adult touch interactions occurring in public, nonintimate settings showed gender asymmetry, but adult touch interactions occurring in greeting or leave-taking settings did not. Cross-sex touch was more prevalent among adults, whereas same-sex touch was more prevalent when a child was involved. Implications for theoretical perspectives on gender and touch are discussed. 相似文献

Complex periodic auditory signals, produced by the Guttman-Julesz procedure of repeating segments of random noise, were employed to address the low region of auditory periodicity. Periodicity detection and discrimination tasks were examined with a common experimental procedure and a common measure of thresholds. Typically, detection and discrimination performance suffer at extremely low periodicities, presumably because of the extremely close spacing of harmonics throughout the auditory spectrum. Interaural phase effects are extremely weak for these signals, being largely confined to threshold-detection tasks. Despite qualitative phenomenological differences for different periodicity regions, detection and discrimination functions show no sharp discontinuities over a wide range of periodicities. 相似文献

A group of 107 children with vascular diseases of the nervous system aged 3-14 years have been studied. In 100 children of the study group acute disturbances of the brain blood circulation have been found, out of which 37 children were with transitory ischemic attacks; 29 were found to be with brain ischaemia; 22-with haemorrhages (7 cases with subarchnoidal, 9 cases with intracerebral and 6 cases with subarachnoidal-parenchimatose); 5 children had wenous thromboses; 7 children were with spinal strokes. In other 7 children we found the presence of Sturge-Weber syndrome. Congenital vascular malformations have been found in 32 children (30%), out of which 16 children (15%) with loops and stenosis of the extracranial segments of the internal carotid artery, and another 16 children (15%) with AV-malformations. Congenital and acquired heart diseases are found to be primary cause for the strokes in 12 children (11%). Considerable is the rate of the epileptic seizures in the acute stage of the strokes as well as of the residual epileptic syndromes. 相似文献

While among 194 high school students 79 first-borns showed less fear of negative consequences of academic success than 78 last-borns and 37 middle-borns, no differences were observed on fear of increased positive attention or of increased responsibility. 相似文献

The goal of the reported experiment was to study how adults judge the meaning of different kinds of smiling and laughing by preschool children, and the role played by other facial movements in determining this meaning. Videotapes and photographs of spontaneous facial expressions of children in a play situation served as stimuli. The results show that different kinds of smiling were judged by the adult subjects as being significantly different from each other. In order to find subgroups within the stimuli, cluster analyses were performed, and the resulting clusters indicated different mixtures of positive and negative emotions contained within the pictures. Regression analyses showed that the adults' judgements were dependent on the number of indicators for positive and negative emotions which could be seen in the pictures. The most important indicator movement for the judged strength of the positive emotion expressed in the smile was the raising of the cheeks and, for negative emotions, the lowering of the lip corners. The significance of the components of the expressions as well as the strength of the expressed emotion were, however, dependent on the mode of presentation (video/photo). 相似文献

We modified the standard procedure for administering finger pressure pain in order to assess the extent to which subjects biased their reports of pain reduction when exposed to compliance-inducing instructions. Experiment 1 used only highly hypnotizable subjects and found that compliance-induced reductions in reported pain were about half as large as the reported reductions produced by hypnotic analgesia suggestions. Experiment 2 used low as well as high hypnotizables and administered hypnotic or nonhypnotic analgesia instructions and compliance instructions to the same subjects on separate pain trials. Reported pain reductions produced by hypnotic and nonhypnotic analgesia suggestions and those produced by compliance instructions were substantially and significantly correlated. Furthermore, hypnotizability correlated with compliance-induced reported pain reductions as highly as it correlated with the reported reductions produced by hypnotic analgesia suggestions. Among high hypnotizables (but not low hypnotizables) compliant responding was predicted by social desirability. The findings of both studies indicate that compliance strongly influences the reports of hypnotic and nonhypnotic analgesia proffered by high hypnotizables. The role of compliance in the pain reductions reported by low hypnotizables is less clear-cut. 相似文献

This case study concerns an 18-year-old bilingual girl who suffered a radiation lesion in the left (dominant) thalamic and temporal region when she was 4 years old. Language and memory assessment revealed deficits in auditory short-term memory, auditory word comprehension, nonword repetition, syntactic processing, word fluency, and confrontation naming tasks. Both languages (English and Dutch) were found to be affected in a similar manner, despite the fact that one language (English) was acquired before and the other (Dutch) after the period of lesion onset. Most of the deficits appear to be related to verbal (short-term) memory dysfunction. Several hypotheses of subcortical involvement in memory processes are discussed with reference to existing theories in this area. 相似文献

Compared stress, coping, and psychological adjustment in single (divorced or separated) and married mothers and their young adolescent children. Single mothers reported more daily hassles related to economic, family, and personal health problems, and more symptoms of depression, anxiety, and psychoticism. Single mothers also reported using more coping strategies related to accepting responsibility and positive reappraisal. After controlling for level of family income, differences in family hassles and coping strategies remained significant. The two groups did not differ on subtypes of symptoms after controlling for income, but single mothers still reported more total psychological symptoms. No differences were found between children in these two family constellations on maternal reports of emotional/behavioral problems or on children's self-reported emotional/behavioral problems, stressful events, or coping. Implications of these findings for adjustment to life in single-parent families are discussed. 相似文献
