The social cognitive capacities of dogs, including their communication skills and use of visual attention cues, have recently
been investigated in numerous experimental studies. This paper reports on research of domestic dog behavior in a natural setting,
which shows sensitivity to the visual attention of their partners when engaged in dyadic rough-and-tumble play. The sequential
behaviors and head-direction of both dogs were noted throughout the bouts. The behaviors were differentially used according
to the partner’s posture. Play signals were sent nearly exclusively to forward-facing conspecifics; attention-getting behaviors
were used most often when a playmate was facing away, and before signaling an interest to play. In addition, the mode of attention-getter
matched the degree of inattentiveness of the playmate: stronger attention-getters were used when a playmate was looking away
or distracted, less forceful ones when the partner was facing forward or laterally. In other words, these dogs showed attention
to, and acted to manipulate, a feature of other dogs that mediates their ability to respond: which feature in human interaction
is called “attention”.

Forensic interviewers guided 46.4‐ to 13‐year‐old alleged victims of sexual abuse to recall the context in which the reported incidents had taken place. A comparable group of 50 alleged victims were interviewed using an interview protocol that was identical except that the mental context reinstatement (MCR) techniques were not included. MCR did not increase the total number of event‐related details reported, but it did lead children to reported proportionally more details (55% versus 46%) in response to invitations rather than focused prompts. Such information is more likely to be accurate. MCR had an especially powerful effect on the youngest children (4‐ to 6‐year‐olds) studied. The results suggest that non‐suggestive contextual cues may indeed be useful in forensic interviews. Published in 2001 by John Wiley & Sons, Ltd. 相似文献

The purpose of the paper is to show that semanticexternalism – the thesis that contents are notdetermined by ``individualistic' features of mentalstates – is mistaken. Externalist thinking, it isargued, rests on two mistaken assumptions: theassumption that if there is an externalist wayof describing a situation the situation exemplifiesexternalism, and the assumption that cases in which adifference in the environment of an intentional stateentails a difference in the state's intentional objectare cases in which environmental factors determine thestate's content. Exposing these mistakes leads to seethat the conditions that are required for thetruth of externalism are inconsistent. 相似文献

The nature of capacity limits (if any) in visual search has been a topic of controversy for decades. In 30 years of work, researchers have attempted to distinguish between two broad classes of visual search models. Attention-limited models have proposed two stages of perceptual processing: an unlimited-capacity preattentive stage, and a limited-capacity selective attention stage. Conversely, noise-limited models have proposed a single, unlimited-capacity perceptual processing stage, with decision processes influenced only by stochastic noise. Here, we use signal detection methods to test a strong prediction of attention-limited models. In standard attention-limited models, performance of some searches (feature searches) should only be limited by a preattentive stage. Other search tasks (e.g., spatial configuration search for a "2" among "5"s) should be additionally limited by an attentional bottleneck. We equated average accuracies for a feature and a spatial configuration search over set sizes of 1-8 for briefly presented stimuli. The strong prediction of attention-limited models is that, given overall equivalence in performance, accuracy should be better on the spatial configuration search than on the feature search for set size 1, and worse for set size 8. We confirm this crossover interaction and show that it is problematic for at least one class of one-stage decision models. 相似文献

This article illustrates a dissociation between the perceived attributes of an object and the ability of those attributes to guide the deployment of attention in visual search. Orientation is an attribute that guides search. Thus, a vertical line will “pop out” amid horizontal distractors. Amodal completion can create perceptually convincing oriented stimuli when two elements appear to form a complete object partially hidden behind an occluder. Previous work (e.g., Rensink &; Enns, Vision Research, 38, 2489–2505, 1998) has shown a preattentive role for amodal completion in search tasks. Here, we show that orientation based on perceptually compelling amodal completion may fail to guide attention. The broader conclusion is that introspection is a poor guide to the capabilities of our internal search engine. 相似文献

This study used vision loss due to age-related macular degeneration to learn about adaptation processes related to chronic functional impairment, focusing on Horowitz and Reinhardt's (1998) concept of Adaptation to Age-related Vision Loss (AVL) as the outcome. We hypothesized that impacts of visual acuity on AVL are mediated by perceived functional vision losses and functional abilities, and tested for "adaptive" weakening of this impact with ongoing loss. Longitudinal data covering a one-year interval from samples with age-related macular degeneration gathered in New York (N = 361) and Heidelberg (Germany, N = 90) were used. We analyzed the hypothesized causal structure by modeling latent change scores, and checked if those with low, medium, and high levels of vision loss at baseline differ in the relations between one-year change scores. Results confirmed that impacts of vision loss on AVL are mediated by decline in functional ability. However, under the most severe levels of vision loss at baseline, functional decline showed only a minor impact on AVL change not explained by a lack of further decline in vision. Findings confirm the effectiveness of adaptation in terms of reduced reactivity to functional losses across increasing level of chronic impairment. Thus, adaptation, weakening the impact of chronic functional impairment on psychological outcomes over time with disease progression, deserves consideration in the study of psychological consequences of chronic physical health conditions in old age. 相似文献

Experiments have shown that people can rapidly determine if categories such as "animal" or "beach" are present in scenes that are presented for only a few milliseconds. Typically, observers in these experiments report on one prespecified category. For the first time, we show that observers can rapidly extract information about multiple categories. Moreover, we demonstrate task-dependent interactions between accumulating information about different categories in a scene. This interaction can be constructive or destructive, depending on whether the presence of one category can be taken as evidence for or against the presence of the other. 相似文献
