视觉选择的过程包含两种途径:眼跳行动和注意转移,两者对于视觉选择目标物的加工都有促进作用。鉴于此,视觉研究领域产生大量关于二者关联如何的实验研究,大部分研究者认为眼跳和注意转移存在密切联系。该文将关于两者关系的重要理论进行了综合阐述和简要比较,主要介绍五种理论假说:眼动准备假说、动前假说、顺序注意模型、视觉注意模型和竞争整合模型。  相似文献

The Müller-Lyer figure is a powerful illusion in both vision and touch, although it is still unclear whether the visual and haptic illusory effects are due to modality-specific or shared processes. In order to investigate the hypothesis of a common underlying mechanism, the performance of 24 undergraduates in a manual bisection task of the Judd variant of the Müller-Lyer figure was assessed under visual, haptic, and visuo-haptic presentations (Experiment 1). In the bimodal condition participants saw the arrowheads on the front and touched the shaft on the back of a stimulus-supporting board. Illusory effects were comparable in touch and vision and were present, albeit reduced, in the bimodal visuo-haptic condition. In Experiment 2 we used the bimodal task of Experiment 1, manipulating the spatial position of the horizontal shaft on the backside of the board. The visual arrowheads affected haptic bisection, bringing about the illusory effects, only when the shaft was aligned with them. In conclusion, illusory effects transfer cross-modally from vision to haptics only in the presence of spatial coincidence, which appears to be a crucial factor for cross-modal integration. Implications for multisensory processes are discussed.  相似文献

Abstract

Drawing on feminist liturgical critiques of prayer, Audre Lorde's notion of the erotic and Carter Heyward's relational theology, amongst other feminist, Womanist, Black and queer sources, this article proposes that prayer via gendered and erotic images of God and Christ may be a site for the integration of gender, sexuality and faith — not only in the life of the individual but in the wider body politic. The notion of integration is problematized alongside heteropatriarchal practices of prayer, and an eschatological understanding of prayer and identity offered. The article argues for prayer which engages with a multiplicity of embodied, erotic and queer images of God (and particularly Christ), as necessary to the complex work of personal and political integration with which prayer is charged as well as gesturing towards the fullness and mystery of God who both inhabits and transcends the limitations of metaphorical discourse about the divine.  相似文献

In face-to-face conversation speech is perceived by ear and eye. We studied the prerequisites of audio-visual speech perception by using perceptually ambiguous sine wave replicas of natural speech as auditory stimuli. When the subjects were not aware that the auditory stimuli were speech, they showed only negligible integration of auditory and visual stimuli. When the same subjects learned to perceive the same auditory stimuli as speech, they integrated the auditory and visual stimuli in a similar manner as natural speech. These results demonstrate the existence of a multisensory speech-specific mode of perception.  相似文献

A multiple baseline design across subjects with a reversal was used to examine the effects of classwide peer tutoring relative to traditional reading instruction on reading skills and social interaction time for 3 high-functioning students with autism and their typical peers in integrated, general education classrooms. Traditional reading instruction consisted largely of teacher-led instruction with individual student participation and seat work. Classwide peer tutoring consisted of 25 to 30 min of well-specified instruction in which tutor—learner pairs worked together on a classwide basis on reading fluency and comprehension skills. All students participated in 15- to 20-min unstructured free-time activities immediately following reading instruction. Results of reading assessments demonstrated that classwide peer tutoring increased reading fluency and correct responses to reading comprehension questions for students with autism and their peers. The procedure further increased the total duration of free-time social interactions for students with autism and typical peers, with individual variation in performance.  相似文献

The study investigates cross-modal simultaneous processing of emotional tone of voice and emotional facial expression by event-related potentials (ERPs), using a wide range of different emotions (happiness, sadness, fear, anger, surprise, and disgust). Auditory emotional stimuli (a neutral word pronounced in an affective tone) and visual patterns (emotional facial expressions) were matched in congruous (the same emotion in face and voice) and incongruous (different emotions) pairs. Subjects (N=31) were required to watch and listen to the stimuli in order to comprehend them. Repeated measures ANOVAs showed a positive ERP deflection (P2), more posterior distributed. This P2 effect may represent a marker of cross-modal integration, modulated as a function of congruous/incongruous condition. Indeed, it shows an ampler peak in response to congruous stimuli than incongruous ones. It is suggested P2 can be a cognitive marker of multisensory processing, independently from the emotional content.  相似文献

Abstract

Although life event research has burgeoned in recent years, little attention has been paid to the prevalence of events among the elderly or their relationship to psychological well-being. This paper presents data from a three-wave longitudinal study of community elderly in Aberdeen. Negative life events were highly prevalent among both survivors [N=349) and non-survivors [N=108], but the relatively small differences between the groups indicate that attrition does not seriously affect longitudinal findings. Longitudinal analysis of survivors' data was performed using LISREL and yielded a model with a goodness of fit index of 0.918, demonstrating a close fit between the data and the model. The model parameters indicate that those in poor psychological state were more likely to report serious non-health events than health events, although the latter were more likely than the former to result in a decline in psychological well-being, even after prior psychological state was taken into account. While elderly people with low social integration experienced more severe reactions to life events in the short term than those with high social integration, there were no significant long term effects, even for those reporting highly stressful events. There was no evidence of a sub-group of elderly people lacked into a cycle of serious life events. However life events were not random occurrences; serious health events were more often reported by those with low education while women and those in lower social classes were more likely to report serious non-health events. Overall, long term disruption, directly attributable to life events, was minimal when viewed within the context of the community elderly's stable psychological state.  相似文献

Previous studies have found a late frontal-central audiovisual interaction during the time period about 150-220 ms post-stimulus. However, it is unclear to which process is this audiovisual interaction related: to processing of acoustical features or to classification of stimuli? To investigate this question, event-related potentials were recorded during a words-categorization task with stimuli presented in the auditory-visual modality. In the experiment, congruency of the visual and auditory stimuli was manipulated. Results showed that within the window of about 180-210 ms post-stimulus more positive values were elicited by category-congruent audiovisual stimuli than category-incongruent audiovisual stimuli. This indicates that the late frontal-central audiovisual interaction is related to audiovisual integration of semantic category information.  相似文献
