Little is known about how social factors influence vulnerability to, and consequences of, HIV infection among men who have sex with men (MSM) in South Africa. This study aimed to analyse social stratification and its links with HIV among MSM in Cape Town, South Africa. Six interviews and six focus group discussions (n = 25) were conducted. Tools were based on the World Health Organisation’s Commission on the Social Determinants of Health framework. Directed content analysis was used to analyse data. Race and education were directly linked to social position. MSM from lower social positions were more vulnerable to HIV, and had more negative consequences of HIV infection, compared to wealthier MSM. Engagement with community leaders, health workers and police to promote inclusion could reduce vulnerability of MSM to HIV. Increased access to free, non-discriminatory HIV-related services would reduce inequities in access to HIV services by MSM. 相似文献

Is processing of conceptual information as robust as processing of perceptual information early in development? Existing empirical evidence is insufficient to answer this question. To examine this issue, 3- to 5-year-old children were presented with a flexible categorization task, in which target items (e.g., an open red umbrella) shared category membership with one test item (e.g., a folded umbrella) and perceptual characteristics with another test item (e.g., a red mushroom). Participants were instructed to either categorize stimuli by the same dimension (i.e., perceptual similarity or category membership) in both phases of the task, or switch from categorizing by one dimension to categorizing by the other dimension. Results pointed to a strong asymmetry in switch costs: conceptual switch costs were higher than perceptual switch costs. These results suggest that processing of perceptual information remains more robust than processing of conceptual information at least until 5 years of age. 相似文献

In human causal learning, positive patterning (PP) and negative patterning (NP) discriminations are often acquired at roughly the same rate, whereas PP is learned faster than NP in most experiments with nonhuman animals. One likely reason for this discrepancy is that most causal learning scenarios encourage participants to treat the presentation and omission of the relevant outcome as two events of comparable significance and likelihood. To investigate this, the current experiments compared PP and NP using a predictive learning paradigm based on a mock gambling task. In Experiment 1, one outcome (winning) was made more salient by being less frequent than the alternative outcome (losing). Under these circumstances, PP was learned faster than NP. In Experiment 2, subjects learned two PP and two NP discriminations, one involved win versus no change outcomes, the other involved lose versus no change outcomes. The subjects learned PP faster than NP, but only when discriminating win from no change. We argue that a difference in difficulty between PP and NP relies on a difference in the salience of the outcomes, consistent with the predictions of a relatively simple model of associative learning. 相似文献

We review recommendations for sequencing instruction in receptive and expressive language objectives in early and intensive behavioral intervention (EIBI) programs. Several books recommend completing receptive protocols before introducing corresponding expressive protocols. However, this recommendation has little empirical support, and some evidence exists that the reverse sequence may be more efficient. Alternative recommendations include teaching receptive and expressive skills simultaneously (M. L. Sundberg & Partington, 1998) and building learning histories that lead to acquisition of receptive and expressive skills without direct instruction (Greer & Ross, 2008). Empirical support for these recommendations also is limited. Future research should assess the relative efficiency of receptive-before-expressive, expressive-before-receptive, and simultaneous training with children who have diagnoses of autism spectrum disorders. In addition, further evaluation is needed of the potential benefits of multiple-exemplar training and other variables that may influence the efficiency of receptive and expressive instruction. 相似文献

In the current set of experiments, we establish, and explore the consequences of, the imprecision that characterizes the attribute response labels typically employed in the Implicit Association Test (IAT). In Experiment 1, we demonstrate the malleability of the IAT, as conventionally implemented. IAT scores are shown to be influenced by perspective mindsets induced by an unrelated preceding task. Then, we explore how the malleability of the IAT can lead to the inference that attitude change has occurred even when there is very good reason to believe it has not (Experiment 2), and conversely, how it can obscure the detection of attitude change when such change is indeed likely to have occurred (Experiment 3). We provide conceptual explanations for these discrepancies and suggest methodological improvements to enhance the specificity of IAT measures. 相似文献

The author discusses the obstacles to symbolization encountered when the analyst appears in the first dream of an analysis: the reality of the other is represented through the seeming recognition of the person of the analyst, who is portrayed in undisguised form. The interpretation of this first dream gives rise to reflections on the meaning of the other’s reality in analysis: precisely this realistic representation indicates that the function of the other in the construction of the psychic world has been abolished. An analogous phenomenon is observed in the countertransference, as the analyst’s mental processes are occluded by an exclusively self‐generated interpretation of the patient’s psychic world. For the analyst too, the reality of the other proves not to play a significant part in the construction of her interpretation. A ‘turning‐point’ dream after five years bears witness to the power of the transforming function performed by the other throughout the analysis, by way of the representation of characters who stand for the necessary presence of a third party in the construction of a personal psychic reality. The author examines the mutual denial of the other’s otherness, as expressed by the vicissitudes of the transference and countertransference between analyst and patient, otherness being experienced as a disturbance of self‐sufficient narcissistic functioning. The paper ends with an analysis of the transformations that took place in the analytic relationship. 相似文献

Attention capture by faces 总被引:2,自引:0,他引:2
We report three experiments that investigate whether faces are capable of capturing attention when in competition with other non-face objects. In Experiment 1a participants took longer to decide that an array of objects contained a butterfly target when a face appeared as one of the distracting items than when the face did not appear in the array. This irrelevant face effect was eliminated when the items in the arrays were inverted in Experiment 1b ruling out an explanation based on some low-level image-based properties of the faces. Experiment 2 replicated and extended the results of Experiment 1a. Irrelevant faces once again interfered with search for butterflies but, when the roles of faces and butterflies were reversed, irrelevant butterflies no longer interfered with search for faces. This suggests that the irrelevant face effect is unlikely to have been caused by the relative novelty of the faces or arises because butterflies and faces were the only animate items in the arrays. We conclude that these experiments offer evidence of a stimulus-driven capture of attention by faces. 相似文献

A questionnaire about how academic performance is evaluated and the importance of teaching and research was completed by 265 faculty at a UK research university. Factor analysis followed by t-tests showed that male faculty had a more realistic understanding of how their research is evaluated, rate the importance of research to their careers more highly, and are more likely than women to work over hours through choice. Women faculty are more likely than men to work over hours because of teaching workload and rate the importance of a teaching qualification more highly, despite giving similar ratings as men to the importance of teaching to their career. The implications for differential rates of promotion are discussed. 相似文献

Research on bilingualism and emotions has shown stronger emotional responses in the native language (L1) compared to a foreign language. We investigated the potential of purposeful second language (L2) use as a means of decreasing the experience of psychological distress. Native Swedish speakers read and answered questions about negative and neutral texts in their L1 (Swedish) and their L2 (English) and were asked to rate their level of distress before or after the questions. The texts and associated questions were either written in the same (within-language), or different languages (cross-language). We found that within-language trials when the text was written in participants’ native language (Swedish–Swedish) resulted in an increase of distress, whilst cross-language trials (Swedish–English) resulted in a decrease of distress. This implies that purposeful second language use can diminish levels of distress experienced following a negative event encoded in one's first language. 相似文献
