ABSTRACT A number of investigators have argued that emotion plays an important role in free-choice learning in settings such as museums, science centers, zoos, and aquariums, particularly given the relationship between emotion and cognition. Despite considerable research on the cognitive aspects of visits, empirical studies on emotion in such settings are virtually non-existent. This study investigated the role that emotion plays in facilitating and enhancing learning at a science center. Three major research questions were addressed: (a) Can emotion be measured using Russell's Affect Grid in a non-laboratory setting such as an interactive science center? (b) If so, do different types of science center experiences create measurably different levels of emotional arousal and/or valence in visitors? and (c) If so, was there evidence that elevated arousal and/or valence enhanced or retarded visitors' long-term cognitive science learning? The study provided evidence that emotion could be measured using a modified Affect Grid technique and that a particular traveling exhibition generated arousal levels above baseline levels as determined by a control group. Findings suggest a relationship between emotional arousal and positive changes in visitor long-term cognition, attitudes, and behaviors. 相似文献

We present neuropsychological evidence indicating that action influences spatial perception. First, we review evidence indicating that actions using a tool can modulate unilateral visual neglect and extinction, where patients are unaware of stimuli presented on one side of space. We show that, at least for some patients, modulation comes about through a combination of visual and motor cueing of attention to the affected side (Experiment 1). Subsequently, we review evidence that action‐relations between stimuli reduce visual extinction; there is less extinction when stimuli fall in the correct colocations for action relative to when they fall in the incorrect relations for action and relative to when stimuli are just associatively related. Finally, we demonstrate that action relations between stimuli can also influence the binding of objects to space, in a patient with Balint's syndrome (Experiment 2). These neuropsychological data indicate that perception–action couplings can be crucial to our conscious representation of space. 相似文献

Abstract The brain is organized into segregated areas of relative functional autonomy and specialization. This basic principle of cerebral organization is well documented for cognitive functions that differ drastically from one another, but less so for functions that belong to the same domain, such as face processing. Yet several sources of evidence point to a functional and structural dissociation of various aspects of face processing, as suggested by (1) an analysis of the perceptual and cognitive demands made by the processing of diverse properties conveyed by facial configurations, (2) selective impairment of aspects of face processing in brain-damaged patients, and (3) different localizations of face cells responsive to properties conveyed by faces such as identity and emotion in the monkey's brain. This study used positron emission tomography (PET) and magnetic resonance imaging (MRI) to delineate better the neurofunctional organization of face processing in the human brain, by measuring cerebral blood flow while subjects performed tasks involving the recognition of faces or the recognition of emotions expressed by faces. The results showed segregated processing of facial identity and facial emotion, with the former being performed predominantly in the ventro-mesial region of the right hemisphere including the limbic system, whereas the latter was carried out predominantly in the latter part of the right hemisphere and the dorsal region of the limbic system. This structural organization allows the parallel processing of different information contained in physiognomies and underlies the high efficiency with which humans process faces. 相似文献

Abstract In three studies, we examined pictorial rehearsal effects in younger and older adults. Concrete and abstract line drawings that varied in the amount of pictorial detail were presented for study under different presentation conditions. In the pictorial rehearsal condition, each picture was followed by a blank rehearsal interval where the picture was no longer presented. In all three experiments, the poststimulus interval enhanced picture recognition for both age groups, relative to a control condition where no rehearsal interval occurred. These findings suggest that older adults, like younger adults, form and maintain visual images across a blank rehearsal interval. Implications of these findings for current views on imaginal processes in older adults are discussed. 相似文献

A growing body of literature has highlighted the increased prevalence of body image concerns and associations with health outcomes among gay and bisexual men (GBM). Little research, however, has examined the link between body image and social oppression for ethnoracialized GBM. Using an intersectionality lens and qualitative inductive analysis, data were collected through focus groups and interviews with GBM (n = 61) who identify with one of four ethnoracial groups (Black, East/Southeast Asian, South Asian, Latino/Brazilian). Three main themes emerged: (1) body image idealization in gay/bisexual male culture, (2) negotiating a racialized body image, and (3) negotiating the impact of body image on relationship with self and others. The study results highlighted how multiple forms of oppression (e.g., racism, sexism) intersected with one another to impact the body image and overall well-being among ethnoracialized GBM. 相似文献

The present work aims to establish a greater understanding of the cognitive mechanisms involved in avoiding distraction from speech and nonspeech sounds. Although mixed results have been presented by research investigating the hypothesis that individuals with superior working memory abilities are better able to avoid acoustic distraction, we found that working memory correlated with some aspects of performance during distraction when carefully examined. This is consistent with the view that working memory involves resisting interference. In a large sample, we examined two different tasks accompanied by acoustic distraction—serial recall and rapid colour naming—as well as two different measures of working memory (operation span and running span). We show that the previous inability to find relations between working memory and avoidance of distraction may stem from the use of inadequate correlational techniques. Additionally, the level of difficulty of the serial recall task may be an important factor. The results illustrate that commonly used statistical techniques can be misleading and furthermore that the ability to avoid distraction from irrelevant items may not be a unitary construct. 相似文献

Following 100 or 300 avoidance training trials, instrumental subjects and their yoked Pavlovian counterparts were tested for generalization of lick suppression along the frequency dimension of the avoidance conditioned stimulus. Gradients of stimulus control were evident after 300 instrumental avoidance training trials, and additional intradimensional Pavlovian discrimination training further sharpened the gradients. After 100 trials, the yoked Pavlovian subjects suppressed more than their instrumental counterparts. However, with increased Pavlovian training, flatter gradients with decreased suppression were obtained. Results from a second experiment revealed that, whereas Pavlovian experience decreased suppression to the tone, subjects suppressed drinking in the presence of static, environmental cues. Data from both experiments supported interpretations that stress the role of response control over environmental events. 相似文献
