Developmental prosopagnosia (DP) is a severe impairment in identifying faces that is present from early in life and that occurs despite no apparent brain damage and intact visual and intellectual function. Here, we investigated what aspects of face processing are impaired/spared in developmental prosopagnosia by examining a relatively large group of individuals with DP (n = 8) using an extensive battery of well-established tasks. The tasks included measures of sensitivity to global motion and to global form, detection that a stimulus is a face, determination of its sex, holistic face processing, processing of face identity based on features, contour, and the spacing of features, and judgments of attractiveness. The DP cases showed normal sensitivity to global motion and global form and performed normally on our tests of face detection and holistic processing. On the other tasks, many DP cases were impaired but there was no systematic pattern. At least half showed deficits in processing of facial identity based on either the outer contour or spacing of the internal features, and/or on judgments of attractiveness. Three of the eight were impaired in processing facial identify based on the shape of internal features. The results show that DP is a heterogeneous condition and that impairment in recognizing faces cannot be predicted by poor performance on any one measure of face processing. 相似文献
Findings that members of minorities are more ready for social contact with members of dominant groups than vice versa have been attributed to a motivation of minorities to integrate into the larger society. We theorize that minorities hold opposing motivations—to integrate vs. to maintain unique group identity—the balance of which determines readiness for out-group contact. Study 1 examined readiness for out-group contact among three groups of Israeli teachers—Jews (dominant group), Muslim Arabs, and Christian Arabs (minorities). According to sociohistorical analyses, Muslim Arabs are more activated to maintain uniqueness and less motivated to integrate than are Christian Arabs. Study 2 examined recent Russian immigrants to Israel (minority) and veteran Israelis (dominant). Individual differences in motivation to integrate vs. maintain minority group identity were measured among immigrants. In both studies, the balance of motivations predicted minority group readiness for contact with the dominant group. 相似文献
The purpose of the present study was to investigate psychological fitness as well as physical fitness among late middle-aged normal men and women before, during, and after a 12-wk. physical activity program. Heart-rate of each subject was measured on a graded treadmill four times, and four psychological measures were taken: self-esteem, body-image, trait-anxiety, and well-being. Improvement of fitness was gradual and significant for both sexes, whereas no effects of time or sex were found on the first three psychological measures. Significant differences in pattern of change between women and men on well-being confirm previous findings that women report more depression and less satisfaction than men and thus are more sensitive to change. 相似文献
It is difficult to ascribe to Hasidism sets of distinctive regional characteristics, because Hasidism transcended both communal and national boundaries. Aware of this problem, the authors of this article seek to characterize Hasidism in Russia, while eschewing the essentialist assumption that Hasidism in Russia had a Russian character. The article describes Hasidism in Tsarist Russia from several perspectives. From an internal Jewish perspective, it discusses features of dynasties of hasidic leaders and the courts they lived in. This is followed by a discussion of relations between hasidic centers (the courts) and hasidic peripheries (the local communities). Relations between Hasidism and the Russian administration are also analyzed, as are the various ways in which hasidim in Russia adapted to the challenges of modernity, while hasidic leaders in Galicia and Hungary were usually more hostile towards modernization. Finally, the article describes the consequences of the upheavals of the First World War, Bolshevik Revolution, and the Civil Wars that followed. During these dramatic events and in their aftermath, the majority of the hasidic leaders in Russia moved to other places in Europe, America, and Palestine, and only some of them remained under the Soviet regime. 相似文献
Integrating findings on the effects of more alternatives with findings on the effects of more attributes, we offer a motivational decision-making model, suggesting that epistemic motivation moderates individuals’ responses to complex information. Study 1 empirically investigated the shared essence of four conceptualizations of epistemic motivation, further distinguishing it from the maximizing/satisficing motivation. A series of experiments indicate that epistemic motivation moderates the effect of complex information on one’s discomfort with a decision (Studies 2–4) and on the tendency to implement one’s choice in action (Study 3). Taken together, our findings indicate that individuals with low epistemic motivation experience more discomfort and are less likely to implement their decision when faced with complex information whereas those high on epistemic motivation portray a weaker or even an opposite effect. The consistent findings across conceptualizations (dispositional Need-for-Cognitive-Closure and manipulated Openness vs. Conservation values) indicate the robustness of the findings and the important role of epistemic motivation in complex decisions. 相似文献
Building on the contributions of diverse theoretical approaches, the authors present a multidimensional model of group identification. Integrating conceptions from the social identity perspective with those from research on individualism-collectivism, nationalism- patriotism, and identification with organizations, we propose four conceptually distinct modes of identification: importance (how much I view the group as part of who I am), commitment (how much I want to benefit the group), superiority (how much I view my group as superior to other groups), and deference (how much I honor, revere, and submit to the group's norms, symbols, and leaders). We present an instrument for assessing the four modes of identification and review initial empirical findings that validate the proposed model and show its utility in understanding antecedents and consequences of identification. 相似文献
Recent research has suggested that not all grapheme-colour synaesthetes are alike. One suggestion is that they can be divided, phenomenologically, in terms of whether the colours are experienced in external or internal space (projector–associator distinction). Another suggestion is that they can be divided according to whether it is the perceptual or conceptual attributes of a stimulus that is critical (higher–lower distinction). This study compares the behavioural performance of 7 projector and 7 associator synaesthetes. We demonstrate that this distinction does not map on to behavioural traits expected from the higher–lower distinction. We replicate previous research showing that projectors are faster at naming their synaesthetic colours than veridical colours, and that associators show the reverse profile. Synaesthetes who project colours into external space but not on to the surface of the grapheme behave like associators on this task. In a second task, graphemes presented briefly in the periphery are more likely to elicit reports of colour in projectors than associators, but the colours only tend to be accurate when the grapheme itself is also accurately identified. We propose an alternative model of individual differences in grapheme-colour synaesthesia that emphasises the role of different spatial reference frames in synaesthetic perception. In doing so, we attempt to bring the synaesthesia literature closer to current models of non-synaesthetic perception, attention and binding. 相似文献
Background: Thyroid chondroplasty is a surgical intervention for reduction of the Adam's apple, performed in trans women to achieve a more feminine appearance of the neck. This procedure is necessary since hormonal therapy given as part of gender affirming medical interventions has no effect on the mature larynx.
Objectives: We aim to describe our thyroid chondroplasty surgical technique and outcome of all thyroid chondroplasties performed during the study period.
Methods: A retrospective chart review of all thyroid chondroplasty procedures performed in a tertiary referral center between 2006 and 2015. Patients' clinical characteristics and surgical outcome were recorded and analyzed.
Results: Twenty-seven trans women underwent thyroid chondroplasty in our institution. Post-operative complications included a single patient who suffered from false vocal fold (ventricular folds) hematoma that resolved spontaneously. Five other patients had an erythematous scar. No other complications were observed.
Conclusion: Thyroid chondroplasty is a safe procedure for achieving a feminine neck contour in trans women. 相似文献
