Religious attendance has generally been salutary for mental health, though recent evidence suggests that church attendance has no significant relation with psychotic experiences. This study will examine how various types of church-based social interactions might be related to psychotic experiences. We analysed data from the National Survey of American Life –a representative sample of Black Americans in the United States –and used multivariable logistic regression to examine associations between seven church-based social interaction variables and lifetime psychotic experiences. In separate models, church attendance, church member interaction, and closeness to church members were not significantly associated with psychotic experiences, while greater emotional support, negative social interactions, providing help to other church members and receiving help from fellow church members were associated with increased odds of reporting psychotic experiences. But in a fully adjusted model including all church-based social interaction variables, only negative church interactions and giving help to church members were significantly associated with psychotic experiences. Church-based social interactions did not protect against psychotic experiences, and in some cases increased risk. Future studies should explore why the deleterious aspects of social interactions prevail over the beneficial ones. 相似文献

Evidence is still inconclusive regarding the locus of the stimulus intensity effect on information processing in reaction tasks. Miller, Ulrich, and Rinkenauer (1999) addressed this question by assessing the intensity effect on stimulus- and response-locked lateralized readiness potentials (LRPs) as indices of the sensory and motor parts of reaction time (RT). In the case of visual stimuli, they observed that application of brighter stimuli resulted in a shortening of RT and stimulus-locked LRP (S-LRP), but not of response-locked LRP (R-LRP). The results for auditory stimuli, however, were unclear. In spite of a clear RT reduction due to increased loudness, neither S-LRP nor R-LRP onset was affected. A reason for this failure might have been a relatively small range of intensity variation and the type of task. To check for this possibility, we performed three experiments in which broader ranges of stimulus intensities and simple, rather than choice, response tasks were used. Although the intensity effect on the R-LRP was negligible, S-LRP followed RT changes, irrespective of stimulus modality. These findings support the conclusion that stimulus intensity exerts its effect before the start of motoric processes. Finally, S-LRP and R-LRP findings are discussed within a broader information-processing perspective to check the validity of the claim that S-LRP and R-LRP can, indeed, be considered as pure estimates of the duration of sensory and motor processes. 相似文献

This paper describes our search for the possible relationship between workers' health and quality of life and several psychosocial risks: Cognitive demands, Control, Rewards and Organizational support. These psychosocial risks were assessed by means of the DECORE Multidimensional Questionnaire, which provides five scores, one for each factor, plus a global score. Workers' health was assessed with the following variables: job satisfaction, stress perception, fatigue perception, medical leave, occupational accidents, and disease. 614 workers from various business sectors were examined. Results show that workers who feel more fatigued, stressed, and less satisfied perceive their work environment more adversely. Similar results were obtained for workers who went on medical leave, had an occupational accident, or suffered from disease. 相似文献

The term "false memories" has been used to refer to suggestibility experiments in which whole events are apparently confabulated and in media accounts of contested memories of childhood abuse. Since 1992 psychologists have increasingly used the term "false memory" when discussing memory errors for details, such as specific words within lists. Use of the term to refer to errors in details is a shift in language away from other terms used historically (e.g., "memory intrusions"). We empirically examine this shift in language and discuss implications of the new use of the term "false memories." Use of the term presents serious ethical challenges to the data-interpretation process by encouraging over-generalization and misapplication of research findings on word memory to social issues. 相似文献

Cultural considerations in social anxiety are a rarely investigated topic although it seems likely that differences between countries in social norms may relate to the extent of social anxiety. The present study investigated individuals' personal and perceived cultural norms and their relation to social anxiety and fear of blushing. A total of 909 participants from eight countries completed vignettes describing social situations and evaluated the social acceptability of the behavior of the main actor both from their own, personal perspective as well as from a cultural viewpoint. Personal and cultural norms showed somewhat different patterns in comparison between types of countries (individualistic/collectivistic). According to reported cultural norms, collectivistic countries were more accepting toward socially reticent and withdrawn behaviors than was the case in individualistic countries. In contrast, there was no difference between individualistic and collectivistic countries on individuals' personal perspectives regarding socially withdrawn behavior. Collectivistic countries also reported greater levels of social anxiety and more fear of blushing than individualistic countries. Significant positive relations occurred between the extent to which attention-avoiding behaviors are accepted in a culture and the level of social anxiety or fear of blushing symptoms. These results provide initial evidence that social anxiety may be related to different cultural norms across countries. 相似文献

Masked threshold for a pure-tone signal can be substantially elevated whenever the listener is uncertain about the spectral or temporal properties of the masker, an effect referred to as auditory informational masking. Individual differences in the effect are large, with young children being most susceptible. When masker uncertainty is introduced by randomizing the frequencies of a multitone masker on each presentation, the function relating a child's pure-tone signal threshold to the number of masker components is found to be substantially elevated above that of most adults. The age effect and the individual differences among adults are not well understood, though a difference in the shapes of the masking functions suggests that different detection strategies may be involved. The present study reports results from a principal components analysis of informational masking functions obtained from 38 normal-hearing children ranging in age from 4 to 16 years and 46 normal-hearing adults ranging in age from 19 to 38 years. The premise underlying the analysis is that if different detection strategies are involved, they should add independent sources of variance to the masking functions. Hence, more than one principal component (PC) should be required to account for a substantial proportion of the variance in these functions. The results, instead, supported the operation of a single underlying strategy with all but 17% of the variance accounted for by the first PC within and across age groups. An analysis of variance on the first two PCs showed that only the first changed with age, and a cluster analysis of the masking functions showed complete separation of clusters along this PC for all but 1 listener. The results are taken to suggest that large individual differences informational masking at all ages reflect differences in the extent to which masker uncertainty adds variance to the decision variable of an otherwise optimal decision strategy. 相似文献

The psychometric properties of the Hooper Vsual Organization Test (VOT) have not been well investigated Here the authors present internal consistency and interrater reliability coefficients, and an item analysis, using data from a sample (N = 281) of "cognitively impaired" and "cognitively intact" patients, and patients with undetermined cognitive status. Coefficient alpha for the VOT total sample was .882. An item analysis found that 26 of the 30 items were good at discriminating among patients. Also, the interrater reliabilities for three raters (.992), two raters (.988), and one rater (.977) were excellent. Therefore, the judgmental scoring of the VOT does not interfere significantly with its clinical utility. The authors conclude that the VOT is a psychometrically sound test. 相似文献

Four cholinesterase inhibitors have been approved by the US Food and Drug Administration for treating behavioral symptoms of Alzheimer's disease. Here we review our experiences with two cholinesterase inhibitors (metrifonate and galanthamine) and a muscarinic acetylcholine receptor agonist (CI-1017) in behavioral pharmacological and brain slice experiments in aging and young rabbits. Aging rabbits are impaired in their ability to acquire the hippocampus-dependent trace eyeblink conditioning task, as compared to young controls. A large proportion of aging animals cannot reach behavioral criterion in this task. Those that do learn, do so more slowly. In addition, the post-burst afterhyperpolarization and spike frequency accommodation is increased in hippocampal pyramidal neurons from aging animals, i.e., cellular excitability is reduced as compared to those from young animals. Metrifonate, galanthamine, and CI-1017 reduced the learning deficits observed in aging rabbits so that they learned almost as quickly as young controls. These cholinergic compounds also enhanced the postsynaptic excitability of hippocampal pyramidal neurons in vitro. Therefore, we propose that the amelioration of learning impairment with the cholinergic compounds may in part be due to the enhanced excitability of hippocampal pyramidal neurons. The potential relevance of our studies to further understanding the cellular and behavioral changes that occur with normal aging and Alzheimer's Disease is discussed. 相似文献

The Torrance Tests of Creative Thinking (TTCT) was developed in 1966 and renormed five times: in 1974, 1984, 1990, 1998, and 2008. The total sample for all six normative samples included 272,599 kindergarten through 12th grade students and adults. Analysis of the normative data showed that creative thinking scores remained static or decreased, starting at sixth grade. Results also indicated that since 1990, even as IQ scores have risen, creative thinking scores have significantly decreased. The decrease for kindergartners through third graders was the most significant. 相似文献
