Adolescent females, particularly urban and low-income youth of color, are at particular risk for HIV infection. This article uses an empowerment perspective to consider the degree to which intrapersonal and interpersonal power dynamics in heterosexual relations have an impact on condom use among high-risk youth. Participants in this study were 333 African American and European American urban youth, ages 14–19 years, who were heterosexually active. Measures focused on interpersonal and intrapersonal factors thought to be associated with condom use. This model was most useful in predicting condom use among women and least useful in predicting condom use among male participants. Implications for empowerment theory and future research are discussed. 相似文献

The purpose of this study was to determine whether common geriatric conditions, family function, and nutritional problems have independent associations with functional dependence beyond the effect of cognitive impairment in patients with Alzheimer's disease. It was found that some common geriatric conditions affecting patients with Alzheimer's disease appear to have multiple and differential relationships with specific instrumental activities of daily living (IADLs) dependency. These results have implications for medical care. Preventing one condition may not be sufficient to prevent further IADL dependences because the conditions are independently related to individual outcome variables. Thus, multiple conditions may need to be managed concurrently if further functional dependence is to be expected. 相似文献

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

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

In this cross‐cultural meta‐analysis, we examine the relationships between person–environment [P–E] fit and work attitudes (organizational commitment, job satisfaction, and intent to quit) as well as job performance based on 96 studies (110 independent samples) conducted in East Asia, Europe, and North America. We compare the results across cultures while focusing on 4 dimensions of P–E fit (person‐job fit, person–organization fit, person–group fit, and person–supervisor fit) separately and jointly. Findings suggest that the effects of rational fit (person–organization and person–job fit) are (relatively) stronger in North America and, to a lesser extent, Europe than in East Asia. However, the effects of relational fit (person–group and person–supervisor fit) are (relatively) stronger in East Asia than in North America. This highlights that in collectivistic and high power distance (vs. individualistic and low power distance) cultures, relational (vs. rational) fit is more salient in influencing employees’ perceptions about their work environments. Results are less clear concerning job performance. What is common across cultures is that, regardless of which dimension of P–E fit is being considered, fit happens and high levels of fit lead to positive outcomes, confirming the universal relevance of fit phenomenon. 相似文献

Although research on emotional intelligence (EI) has shown that EI is positively associated with successful work outcomes, little is known about why this is true. The present study hypothesized and tested the intervening process of situational judgment effectiveness (SJE) in the relationships between EI and work attitudes. Using survey responses from 288 employees in South Korea, we found that EI was positively associated with SJE and work attitudes (job satisfaction and organizational commitment), and that the relationships between EI and the work attitudes were partially mediated by SJE. Overall, our finding has incremental contribution to the EI and work attitudes literatures by demonstrating that SJE plays an important role in understanding the EI–work attitudes relationship. 相似文献
