Empirical data regarding the extent of face recognition abnormalities in autism spectrum disorder (ASD) is inconsistent. Here, 27 ASD and 47 typically developing (TD) children completed an immediate two-alternative forced-choice identity matching task. We contrasted recognition of own- and other-race faces, and, counter to prediction, we found a typical advantage for recognizing own- over other-race faces in both the ASD and TD groups. In addition, ASD and TD groups responded similarly to stimulus manipulations (use of identical or different photographs for identity matching and cropping stimuli to remove hair information). However, age-standardized scores varied widely within the ASD sample, and a subgroup of ASD participants with impaired face recognition did not exhibit a significant own-race recognition advantage. An explanation regarding early experience with faces is considered, and implications for research of individual variation within ASD are discussed. 相似文献

A central aim of cognitive psychology is to explain how we integrate stimulus dimensions into a unified percept, but how the dimensions of pitch and time combine in the perception of music remains a largely unresolved issue. The goal of this study was to test the effect of varying the degree of conformity to dimensional structure in pitch and time (specifically, tonality and metre) on goodness ratings and classifications of melodies. The pitches and durations of melodies were either presented in their original order, as a reordered sequence, or replaced with random elements. Musically trained and untrained participants (24 each) rated melodic goodness, attending selectively to the dimensions of pitch, time, or both. Also, 24 trained participants classified whether or not the melodies were tonal, metric, or both. Pitch and temporal manipulations always influenced responses, but participants successfully emphasized either dimension in accordance with instructions. Effects of pitch and time were mostly independent for selective attention conditions, but more interactive when evaluating both dimensions. When interactions occurred, the effect of either dimension increased as the other dimension conformed more to its original structure. Relative main effect sizes (| pitch η(2) - time η(2) |) predicted the strength of pitch-time interactions (pitch?×?time η(2)); interactions were stronger when main effect sizes were more evenly matched. These results have implications for dimensional integration in several domains. Relative main effect size could serve as an indicator of dimensional salience, such that interactions are more likely when dimensions are equally salient. 相似文献

Throughout history, humans have had to detect and deflect myriad threats from their social and physical environment in order to survive and flourish. When people detect a threat, the most common response is avoidance. In the present research, the authors provide evidence that ingroup power threats elicit a very different response. Three experiments supported the hypothesis that dominant leaders seek proximity to ingroup members who pose a threat to their power, as a way to control and downregulate the threat that those members pose. In each experiment, leaders high (but not low) in dominance motivation sought proximity to an ingroup member who threatened their power. Consistent with the hypothesis that increased proximity was designed to help leaders protect their own power, the proximity effect was apparent only under conditions of unstable power (not stable power), only in the absence of intergroup competition (not when a rival outgroup was present), and only toward a threatening group member (not a neutral group member). Moreover, the effect was mediated by perceptions of threat (Experiment 1) and the desire to monitor the threatening group member (Experiment 3). These results shed new light on one key strategy through which dominant leaders try to maintain control over valuable yet potentially threatening group members. Findings have implications for theories of power, leadership, and group behavior. 相似文献

Alcohol misuse increases risk of suicidal behavior in older adults. The Depressive Symptom Inventory‐Suicidality Subscale (DSI‐SS; Metalsky & Joiner, 1997) and its relation to suicide attempt history was examined to see if it differed for older adults as a function of their alcohol use. Structural equation modeling was used in a sample (N = 1,061) of older adult outpatients to examine the scale’s measurement invariance and population heterogeneity and its relation to suicide attempt history. Analyses supported the equivalence of the DSI‐SS in risky and nonrisky drinkers. The DSI‐SS significantly predicted past suicide attempts. Findings support the viability of the DSI‐SS as suicide screening tool for older adults. 相似文献

Although the Autobiographical Memory Test (AMT) is widely used its psychometric properties have rarely been investigated. This paper utilises data gathered from a 10-item written version of the AMT, completed by 5792 adolescents participating in the Avon Longitudinal Study of Parents and Children, to examine the psychometric properties of the measure. The results show that the scale derived from responses to the AMT operates well over a wide range of scores, consistent with the aim of deriving a continuous measure of over-general memory. There was strong evidence of group differences in terms of gender, low negative mood, and IQ, and these were in agreement when comparing an item response theory (IRT) approach with that based on a sum score. One advantage of the IRT model is the ability to assess and consequently allow for differential item functioning. This additional analysis showed evidence of response bias for both gender and mood, resulting in attenuation in the mean differences in AMT across these groups. Implications of the findings for the use of the AMT measure in different samples are discussed. 相似文献

Women are commonly offered testing in pregnancy to determine the health of their baby. An important component of informed
decision-making about prenatal testing is provision of relevant, accurate, meaningful information concerning the conditions
that are being tested for—many of which, such as Down syndrome, are associated with a varying degree of physical and intellectual
disability. A range of health professionals, including genetic counselors, may provide information and support throughout
the testing process, but available data suggest that discussion of disability is frequently absent or limited. To investigate
genetic counselors’ perceptions of this situation and identify potential barriers to discussion we facilitated interactive
workshops at the 2007 National Society of Genetic Counselors Annual Education Conference (NSGC) and the 2008 European Meeting
on Psychosocial Aspects of Genetics (EMPAG). Working groups identified relevant psychosocial issues and impediments to discussion
(NSGC) or used a two-part scenario to promote discussion (EMPAG) and reported findings in notes and a closing plenary discussion.
Inductive content analysis revealed that participants considered informed decision making to be a major reason for presenting
information about disabilities in prenatal genetic counseling and endorsed the value of including information about daily
life with Down syndrome and other disabilities. However, they identified three broad types of impediments to such discussion:
counseling issues concerning the most appropriate manner to discuss disability under the complex circumstances of prenatal
genetic counseling, less than optimal training and experience in addressing these issues, and perceived limitations in the
participants’ knowledge and understanding of life with disability. Our analysis of the responses from the workshop participants
and additional thoughts on these issues have led us to develop recommendations for further research, training and clinical
practice. 相似文献

The direct‐supervision style correctional facility has been offered as a design that provides a better atmosphere for staff and inmates. Prior research has shown minor support in favor of the general environment created by direct‐supervision facilities. However, the claims of benefits associated with direct supervision far outweigh the number of empirical research studies on the design. This research examined corrections officers' and inmates' feelings of boredom, perceived control, aggression, attitudes toward each other, and stress in a direct‐supervision style facility and a remote‐supervision style facility. Results from 164 inmates and 82 correctional officers showed that staff in the direct‐supervision facility reported elevated levels of perceived control, less anger and hostility, and less boredom. 相似文献

In two experiments we explored how the dimensions of pitch and time contribute to the perception and production of musical sequences. We tested how dimensional diversity (the number of unique categories in each dimension) affects how pitch and time combine. In Experiment 1, 18 musically trained participants rated the complexity of sequences varying only in their diversity in pitch or time; a separate group of 18 pianists reproduced these sequences after listening to them without practice. Overall, sequences with more diversity were perceived as more complex, but pitch diversity influenced ratings more strongly than temporal diversity. Further, although participants perceived sequences with high levels of pitch diversity as more complex, errors were more common in the sequences with higher diversity in time. Sequences in Experiment 2 exhibited diversity in both pitch and time; diversity levels were a subset of those tested in Experiment 1. Again diversity affected complexity ratings and errors, but there were no statistical interactions between dimensions. Nonetheless, pitch diversity was the primary factor in determining perceived complexity, and again temporal errors occurred more often than pitch errors. Additionally, diversity in one dimension influenced error rates in the other dimension in that both error types were more frequent relative to Experiment 1. These results suggest that although pitch and time do not interact directly, they are nevertheless not processed in an informationally encapsulated manner. The findings also align with a dimensional salience hypothesis, in which pitch is prioritised in the processing of typical Western musical sequences. 相似文献
