Picture and pattern perception in the sighted and the blind: the advantage of the late blind 总被引:1,自引:0,他引:1
M A Heller 《Perception》1989,18(3):379-389
Two experiments are reported on the contribution of visual experience to tactile perception. In the first experiment, sighted, congenitally blind, and late blind individuals made tactual matches to tangible embossed shapes. In the second experiment, the same subjects attempted tactile identification of raised-line drawings. The three groups did not differ in the accuracy of shape matching, but both groups of blind subjects were much faster than the sighted. Late blind observers were far better than the sighted or congenitally blind at tactile picture identification. Four of the twelve pictures were correctly identified by most of the late blind subjects. The sighted and congenitally blind performed at comparable levels in picture naming. There was no evidence that visual experience alone aided the sighted in the tactile task under investigation, since they performed no better than did the early blind. The superiority of the late blind suggests that visual exposure to drawings and the rules of pictorial representation may help tactile picture identification when combined with a history of tactual experience. 相似文献

Abstract. Some physical aspects of Teilhard's synthesis are focused upon and confronted with the recent achievements of physics and cosmology. The stuff of the universe, according to modern physical theories, has become something more similar to a structure or form than to inert pieces of material substratum. Directedness of time and history no longer seems to be an ontological a priori of any existence, but rather an outcome of finely tuned initial conditions. And the growth of complexity is now regarded as a process emerging out of physical laws rather than a foreign element in the body of physics. The question is considered of how these results affect Teilhard de Chardin's vision of the world. 相似文献

Subjects in five experiments matched tangible braille against a visible matching code. In Experiment 1, braille recognition suffered when entire lines of braille characters were tilted in varying amounts from the upright. Experiment 2 showed that tilt lowered performance for tangible, large embossed letters, as well as for braille. However, recognition was better for print letters than it was for braille. In Experiment 3, subjects attempted to match the upright array against embossed braille that was left/right reversed, inverted up/down, or rotated +180°. Performance was close to that for normal braille in the left/right reversal condition, and very low for the +180° rotation group. These results on braille tilt in the “picture plane” may reflect difficulty in manipulating the tangible “image.” Braille recognition performance was not lowered whenthe visible matching array was tilted ?45° or ?90° from the upright but the tangible stimuli were upright. In Experiment 4, recognition of left/right reversed braille that was physically horizontal (on the bottom of a shelf) was compared with that of braille left/right reversed due to its location on the back of a panel, in the vertical plane. Braille recognition accuracy was higher with braille located vertically. An additional experiment showed the beneficial effect of locating braille in the vertical, frontoparallel plane, obtained with +90° degree rotated braille. It is proposed that optimal tactual performance with tangible arrays might depend on touching position, and on the physical position of stimuli in space. Just as there are good and poor viewing positions, there may be optimal touching positions. The effects of tilt on braille identification were diminished for blind subjects, suggesting the importance of tactile experience and skill. 相似文献

A conceptual reorientation for providing responsive psychological services to older adults is presented, focusing on the need to develop prevention programs for older adults that encourage the maintenance of useful social roles. Changes in social structures that encourage more active social engagement are discussed, with examples drawn from housing options, part-time employment, and ways to develop more supportive social ties for older adults faced with network losses. Counselors and other mental health specialists can play a useful role in helping the public understand the social dilemmas faced by older adults and the value of their continued integration as useful citizens. 相似文献

The rationale and problems encountered in implementing a peer-support telephone intervention are described. The research conducted by Heller, Thompson, Trueba, Hogg, and Vlachos-Weber (1991) was based on epidemiological literature documenting the moral enhancing value of confidante relationships. However, that literature may be insufficiently precise to form the basis for an intervention without prior ethnographic study of the local target population. Furthermore, the positive effects of peer friendships may refer to long established relationships rather than to newly formed social ties. It is concluded that future support intervention research with older adults should concentrate on reinforcing meaningful role activities, and that greater attention should be given to strengthening indigenous ties before attempting to create new ones. While prior process research and formative evaluation are of value, we also emphasize the importance of well-controlled field studies in the ultimate test of intervention hypotheses. 相似文献

Past research suggests that aggressive children misattribute hostile intentions to peers during ambiguous provocative interactions. This study sought to extend the analysis of attributional differences between aggressive and nonaggressive boys to a sample of court-involved adolescents and their perceptions of interactions involving both peers and adults. Three groups of youngsters (nonoffenders, nonaggressive offenders, and aggressive offenders) participated in a structured interview and provided causal attributions for interpersonal problems commonly faced by teenagers. Results indicated that offenders were more likely than nonoffenders to attribute blame to others in ambiguous problem situations. Among offenders, external, person-centered blame attributions were significantly related to aggressiveness. This relationship was found only in ambiguous situations, and the correlation between such person-centered attributions and aggressiveness was higher in adult-oriented interactions than in peer-oriented ones. Overall, the results suggest that aggressiveness among offenders is associated with an attributional style that is characterized by the tendency to attribute blame for problems in ambiguous interactions to global, dispositional characteristics of others. 相似文献

In four experiments, subjects were required to identify sequences of random digits, letters, or words drawn on the skin. The passive tactile digit span was determined to be three items when the digits were drawn with an interstimulus interval of 1 sec. Identification was significantly better for words than for random letter sequences. Slower rates of presentation produced better tactile retention. The deficiencies in passive retention were ascribed to two processes, the generation of aftersensations and a difficulty in the generation of a unitary percept. Perceptual activity may normally act to inhibit aftersensations and facilitate the construction of a unitary percept The results supported the notion that the tactile span of immediate memory is labile and may be limited by passivity. 相似文献

The high comorbidity of depression and anxiety is well established empirically but not well understood conceptually, in terms of either psychological or biological mechanisms. A neuropsychological model of regional brain activity in emotion provides contrasting hypotheses for depression and anxiety, with depression associated with a relative decrease and anxiety with a relative increase in right-posterior activity. These hypotheses received support in a comparison of individuals diagnosed with depression and community controls, and also in a separate study of nonpatients administered a measure of perceptual asymmetry. Hierarchical regressions revealed that depression and anxiety were uniquely and jointly associated with perceptual asymmetry. In light of consistent empirical support for the model, implications for conceptualizations of the comorbidity of depression and anxiety are discussed. 相似文献
