The phenomenon of change blindness (the surprising inability of people to correctly perceive changes between consecutively presented displays), primarily reported in vision, has recently been shown to occur for positional changes presented in tactile displays as well. Here, we studied people’s ability to detect changes in the number of tactile stimuli in successively presented displays composed of one to three stimuli distributed over the body surface. In Experiment 1, a tactile mask consisting of the simultaneous activation of all seven possible tactile stimulators was sometimes presented between the two to-be-discriminated tactile displays. In Experiment 2, a “mudsplash” paradigm was used, with a brief irrelevant tactile distractor presented at the moment of change of the tactile display. Change blindness was demonstrated in both experiments, thus showing that the failure to detect tactile change is not necessarily related to (1) the physical disruption between consecutive events, (2) the effect of masking covering the location of the change, or (3) the erasure or resetting of the information contained within an internal representation of the tactile display. These results are interpreted in terms of a limitation in the number of spatial locations/events that can be consciously accessed at any one time. This limitation appears to constrain change-detection performance, no matter the sensory modality in which the stimuli are presented. 相似文献

The Rey Auditory Verbal Learning Test was utilized to examine attention, learning, and memory abilities in 42 children with cerebellar (N = 18) and third ventricle tumors (N = 24). Children with cerebellar tumors exhibited significant auditory attentional impairments and displayed adequate encoding and retrieval across subsequent learning and memory trials. In contrast, children with third ventricle tumors exhibited average auditory attentional abilities, but they displayed mild encoding deficits across trials 2-5. Furthermore, the third ventricle group's compromised performance on the delayed recall trial and average performance on the delayed recognition trial is suggestive of underlying retrieval deficits. 相似文献

Migration and psychological status of adolescents in Turkey 总被引:2,自引:0,他引:2
The aim of this study was to investigate the influence of involuntary migration on an adolescent population that had moved with their families to either one of two culturally different locations in Turkey. One of these groups had moved from a village in Eastern Turkey to a nearby town, while the other had moved a considerable distance to a large city in Western Turkey. Comparison groups included adolescents from both regions who had never migrated. Measures of self-esteem, satisfaction with life, and social support networks were used with 305 adolescents who were between the ages of 12 and 15. Adolescents who had migrated scored lower on self-esteem and life satisfaction, and had fewer people in their social support networks than those who had not. It was also found that those who had migrated tended to be more dependent on peers than family for social support. This was probably the case because school attendance was lower for migrants, particularly for males, and the probability of full time work on the street away from their families was considerably higher. 相似文献

To date, numerosity judgments have been studied only under conditions of unimodal stimulus presentation. It is therefore unclear whether the same limitations on correctly reporting the number of unimodal visual or tactile stimuli presented in a display might be expected under conditions in which participants have to count stimuli presented simultaneously in two or more different sensory modalities. In Experiment 1, we investigated numerosity judgments using both unimodal and bimodal displays consisting of one to six vibrotactile stimuli (presented over the body surface) and one to six visual stimuli (seen on the body via mirror reflection). Participants had to count the number of stimuli regardless of their modality of presentation. Bimodal numerosity judgments were significantly less accurate than predicted on the basis of an independent modality-specific resources account, thus showing that numerosity judgments might rely on a unitary amodal system instead. The results of a second experiment demonstrated that divided attention costs could not account for the poor performance in the bimodal conditions of Experiment 1. We discuss these results in relation to current theories of cross-modal integration and to the cognitive resources and/or common higher order spatial representations possibly accessed by both visual and tactile stimuli. 相似文献

There appears to be an interesting paradox in American attitudes toward racial inequality: while Americans almost universally see inequality as a social evil, they also consistently oppose government programs to remedy it. This discrepancy appears to result from accounts for the causes of inequality: if inequality is caused by individual failures, rather than structural conditions, then government solutions to racial inequality are unlikely. We examine the role of religion in the formation of attitudes concerning racial inequality for both blacks and whites. Using logistic regression on data from the 1996 General Social Survey, we find that the inclusion of African Americans and multiple religious traditions further complicates the story behind contemporary debates over attitudes pertaining to racial inequality. 相似文献

Described as the ‘face of American culture’, World Wrestling EntertainmentTM (WWE) events are broadcast in over 162 countries and draw more than 500 million regular viewers. This paper explores the proposition that the WWE fan base represents a product‐based subculture in American society. Using a value laddering methodology, shared values of WWE fans are exposed and the proposition of core and unique cultural values is supported. Practitioner and theoretical implications of the results are discussed. Copyright © 2004 Henry Stewart Publications. 相似文献

This study assessed the efficacy of a time-sensitive cognitive remediation summer program (CRSP) that provided patients and their families with tools to help mitigate neurocognitive deficits and promote independence to foster precursor transition of medical care skills. A total of 38 participants (aged 9–15) were included in one of the CRSPs offered yearly from 2013 to 2016. A longitudinal design was employed and at each evaluation time point, one week before start of the CRSP (pre-testing) and within three weeks after the end of the program (post-testing)), participants were administered measures of executive functioning in addition to parent ratings of behavior, executive functioning, and adaptive skills (Year 1–Year 4). In Year 4, additional measures were collected, including parenting style and parent engagement and involvement in the program. Results from Year 1 to Year 4 (n = 35) demonstrated that participants in the CRSP showed significant improvement on neuropsychological testing in sustained and selective attention, planning, and cognitive flexibility. Robust changes in parent ratings of adaptive functioning from pre- to post-treatment were also found. Specific to Year 4 (n = 13), results revealed that participants showed improvement in levels of independence with at least one of the individualized goals focused on during the program. This study provided a systematic method to gauge the levels of instruction necessary to reach goals, a crucial tool in skill-teaching. Overall, our study provides evidence for the efficacy of the CRSP and validates a feasible intervention that can be integrated into standard of care for pediatric medical populations. 相似文献
