Previous research suggests that understanding the gist of a scene relies on global structural cues that enable rapid scene categorization. This study used a repetition blindness (RB) paradigm to interrogate the nature of the scene representations used in such rapid categorization. When stimuli are repeated in a rapid serial visual presentation (RSVP) sequence (~10 items/sec), the second occurrence of the repeated item frequently goes unnoticed, a phenomenon that is attributed to a failure to consolidate two conscious episodes (tokens) for a repeatedly activated type. We tested whether RB occurs for different exemplars of the same scene category, which share conceptual and broad structural properties, as well as for identical and mirror-reflected repetitions of the same scene, which additionally share the same local visual details. Across 2 experiments, identical and mirror-image scenes consistently produced a repetition facilitation, rather than RB. There was no convincing evidence of either RB or repetition facilitation for different members of a scene category. These findings indicate that in the first 100–150 ms of processing scenes are represented in terms of local visual features, rather than more abstract category-general features, and that, unlike other kinds of stimuli (words or objects), scenes are not susceptible to token individuation failure. 相似文献

One hundred alleged victims of child sexual abuse (aged 4–13; M = 9.3 years) were interviewed by police investigators about their alleged experiences. Half of the children were interviewed using the National Institute of Child Health and Human Development (NICHD) structured interview Protocol, whereas the other children, matched with respect to their age, relationship with the alleged perpetrator, and seriousness of the alleged offenses, were interviewed by investigators following the Memorandum of Good Practice. Protocol‐guided interviews elicited more information using free‐recall invitations and less information using directive, option‐posing and suggestive questions than did standard Memorandum interviews. There were no age differences in the proportion of total information provided in response to open‐ended invitations in either condition, but there was a significant increase with age in the proportion of central information provided in response to open‐ended invitations.

This longitudinal field study aimed to: (a) examine the relative importance of reactions to psychological tests compared to interviews; (b) compare reactions to selection procedures with perceptions of job and organizational attributes; and (c) examine the relative importance of job acceptance intentions assessed at different stages. Graduate applicants were surveyed at four time points: pre‐selection, after an external interview, after psychological tests and internal interviews, and after actual job acceptance decision. Reactions to psychological tests were unrelated to attractiveness and acceptance intentions, whereas mixed findings were reported on reactions to interviews. Mostly, the findings showed that perceptions of job and organizational attributes explained significant variance in attractiveness and job acceptance intentions, whereas reactions to selection procedures were unrelated. The hypothesis that acceptance intentions closest in time to job acceptance decision would be more strongly related to job acceptance decision compared to intentions assessed at early stages was not supported. In general, the results emphasised the relative importance of initial attitudes of applicants in understanding applicant reactions. 相似文献

Individuals with autism show a complex profile of differences in imitative ability, including a general deficit in precision of imitating another’s actions and special difficulty in imitating nonmeaningful gestures relative to meaningful actions on objects. Given that they also show atypical patterns of visual attention when observing social stimuli, we investigated whether possible differences in visual attention when observing an action to be imitated may contribute to imitative difficulties in autism in both nonmeaningful gestures and meaningful actions on objects. Results indicated that (a) a group of 18 high-functioning 8- to 15-year-olds with autistic disorder, in comparison with a matched group of 13 typically developing children, showed similar patterns of visual attention to the demonstrator’s action but decreased attention to his face when observing a model to be imitated; (b) nonmeaningful gestures and meaningful actions on objects triggered distinct visual attention patterns that did not differ between groups; (c) the autism group demonstrated reduced imitative precision for both types of imitation; and (d) duration of visual attention to the demonstrator’s action was related to imitation precision for nonmeaningful gestures in the autism group. 相似文献

Many individuals with Tourette syndrome and chronic tic disorders (TS/CTDs) report poor social functioning and comorbid social anxiety. Yet limited research has investigated the role of cognitive factors that highlight social threats in youth with TS/CTD, and whether these biases underlie tic severity and co-occurring social anxiety. This study examined whether selective attention to social threat is enhanced young people with TS/CTDs compared to healthy controls, and whether attention biases are associated with tic severity and social anxiety. Twenty seven young people with TS/CTDs and 25 matched control participants completed an experimental measure of attention bias toward/away from threat stimuli. A clinician-rated interview measuring tic severity/impairment (YGTSS Total Score) and questionnaire measures of social anxiety were completed by participants and their parents. Young people with TS/CTD showed an attention bias to social threat words (relative to benign words) compared to controls but no such bias for social threat faces. Attention bias for social threat words was associated with increasing YGTSS Total Score and parent-reported social anxiety in the TS/CTDs group. Mediation analysis revealed a significant indirect path between YGTSS Total Score and social anxiety, via attention to social threat. Tentatively, these associations appeared to be driven by impairment rather than tic severity scores. Preliminary data suggests that youth with TS/CTD have enhanced attention to threat, compared to controls, and this is associated with impairment and social anxiety. Attention to threat could offer a cognitive mechanism connecting impairment and social anxiety, and so be a valuable trans-diagnostic treatment target. 相似文献

This article applies a market mechanism derived from principles of welfare economics to a social dilemma simulation in the laboratory. In Study 1, half of the five-person groups were offered the opportunity to voluntarily "buy-out" one or more group members in an effort to conserve a shared, scarce resource. Most groups offered the intervention achieved at least one member buy-out per game. Yet, despite the smaller size of the groups, these groups did not sustain the resource pool any longer than control groups that were left intact. In fact, the results were in the opposite direction. Subjects behaved in a more self-interested manner. In Study 2, the "buy-out" intervention was varied to test the robustness of Study 1′s result. It was found that the intervention was not sensitive to changes in the specifics of operationalization. Discussion is offered regarding the complexity of market-based interventions in social choice situations and the need for improved understanding of the micro-mediating links between market dynamics and individual- and group-level behavior. 相似文献

The Yale Children's Inventory (YCI), a parent based rating scale, and the scales derived from it have been developed to identify and measure multiple dimensions of learning disabilities with particular emphasis on attentional deficits. Scale construction was based on factor analytic procedures. Measures of internal consistency, test retest reliability, and coefficients of congruence support the reliability and stability of the 11 scales. A discriminant function classified normal and learning disabled children with a relatively high rate of accuracy. The relationship and content of the three relevant YCI scales were compared to the DSM-III diagnostic categories for ADD. As operationalized, DSM-III criteria for hyperactivity formed a cohesive factor, while criteria for attention and impulsivity were not distinguishable from each other since they loaded together on a single factor. In contrast, the equivalent YCI scales for attention, impulsivity, and hyperactivity were found to be distinct. 相似文献

An embodied approach to the perception of spatial layout contends that the body is used as a 'perceptual ruler' with which individuals scale the perceived environmental layout. In support of this notion, previous research has shown that the perceived size of objects can be influenced by changes in the apparent size of hand. The size-weight illusion is a well known phenomenon, which occurs when people lift two objects of equal weight but differing sizes and perceive that the larger object feels lighter. Therefore, if apparent hand size influences perceived object size, it should also influence the object's perceived weight. In this study, we investigated this possibility by using perceived weight as a measure and found that changes in the apparent size of the hand influence objects' perceived weight. 相似文献

The research literature has demonstrated that battered women living in shelters experience impaired social support. This study examines this phenomenon among battered women living in the community. This study compared a group of pregnant battered women (n = 145) and a group of pregnant nonbattered women (n = 58) in terms of their structural [e.g., total number of supporters, network members in violent relationships with their partners (an index of homophily or nonhomophily) and functional (e.g., emotional)] social support. Four reasons for impaired support in battered women were proposed and examined, including social isolation, failure to disclose abuse, homophily, and low SES. Only homophily was related to impaired support among battered women. In addition, the relationship between structural and functional support and mental health outcomes (e.g., depression, self-esteem) was examined. Criticism, practical support, homophily, and disclosure were all significant predictors of mental health for battered women. Implications for community-based interventions are discussed in the context of current intervention strategies with battered women. 相似文献
