Subjects were asked to rate their fear of four categories of animals both before and after viewing one of three brief video films. Subjects watched either (a) a video depicting extreme violence, (b) a video depicting revulsive scenes from a hospital operation, or (c) a video showing neutral landscape scenes. The results suggested that exposure to violent material produced an increase in fear ratings for animals in the Hi Fear/Hi Predatory category (e.g., lion, tiger, shark) which was significantly different from a decrease in fear ratings recorded for all other categories of animals. However, exposure to revulsive material produced an increase in fear ratings to animals in both the Hi Fear/Lo Predatory category (e.g., rat, spider, snake) and the Hi Revulsion category (e.g., slug, maggot, snail) which was significantly different to the decrease in fear ratings recorded for animals in the remaining categories. The neutral landscape scenes produced a decrease in mean fear ratings for all categories of animals. These results are considered further support for a disease-avoidance model of common animal fears, and suggest a causal link between disgust sensitivity and fear of certain fear-relevant animals. 相似文献

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 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

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

We investigated the readability of seven mental health brochures on mental, emotional, and behavioral disorders in children that were selected from a website developed by the Center for Mental Health Services at http://www.mentalhealth.org. The reading grade levels of the brochures ranged from 11.1 to 14.8 (mean 13.23), considerably higher than the 8th grade level recommended for educational material by the U. S. Department of Education (1986). On other readability variables, assessed using the Readability Assessment Instrument (RAIN; Singh, 1994), all brochures met criterion on most variables but failed on those for new words (audience appropriateness) and print size. This is a favorable result in comparison with other studies that have assessed readability of mental health information on the Internet using the RAIN, although less so with reading grade levels. 相似文献

This article reports a second-order factor analysis of the 13 interpretable first-order factors of Adkins and Lyerly based on 66 variables for 200 Army men. The approach to simple structure for 6 second-order factors was unusually good. Loadings of the original 66 variables on the second-order factors were also obtained. Five of the factors are tentatively interpreted as Precision in Formation and Use of Verbal Concepts, General Verbal Fluency, Visualizing Spatial Constancy During Movement, Speed in Analysis, and Flexibility in Analysis. 相似文献

The relations of abilities, as measured by Thurstone'sTests for Primary Mental Abilities, to activity preferences, as measured by Kuder'sPreference Record, are investigated for a population of 512 university freshmen. Ability profiles for contrasted groups on each preference scale reveal relatively slight overlapping between the two sets of measures, although the apparent trends are reasonable. The Pearson inter-correlation coefficients of all pairs of measures involved were determined. Implications of the findings in relation to theory and to educational and vocational guidance are indicated. 相似文献
