A computerized bibliography of references relating to "touch" has been prepared. It currently contains approximately 4000 references which belong under the following general categories--physiology and neurophysiology; sensation; perception; cognition; social, cultural, and developmental issues; clinical pathology; the deaf and blind; tactile communication and tactile aesthetics. References have been obtained primarily from the Psychological Abstracts, with classification codes added on the basis of the abstract's content. Master copies and keyword searches may be obtained on the most up-to-date version of the bibliography. 相似文献

Two nonverbal methods for assessing degree of interpersonal attraction were explored. Twenty children ranging from 11 to 13 years of age were asked to select two liked and two disliked classmates of the same sex. On four different trials, subjects selected one geometric block to represent themselves and one to represent a pre-selected classmate, then placed the figures on a ruled board. Distance between objects was measured and found to be significantly related to degree of peer liking. In addition, subjects were asked to draw each of the four peers. The human figure drawings were rated for total pictorial detail which was found to vary strongly across magnitude of liking for female subjects, and for parts integration which was found to vary with degree of peer liking for both sexes. The degree of rated positive affective tone of drawings was also found to increase with liking. Implications for the use of these two interpersonal assessment techniques in clinical practice were discussed. 相似文献

Squirrel monkeys were periodically exposed to brief electric tail shocks in a test environment containing a rubber hose, response lever, and a water spout. Shock delivery produced preshock lever pressing and postshock hose biting. Additionally, all subjects displayed licking responses following postshock biting-attack episodes. Further experiments showed that licking was: (1) influenced by hours of water deprivation; (2) drinking behavior; (3) the direct result of shock delivery; and (4) developed spontaneously in naive subjects with or without opportunities for hose biting or lever pressing. Removing the opportunity to attack increased postshock drinking. A noxious environmental stimulus that causes aggression can also produce drinking. 相似文献

An instance of fruitful cross-disciplinary contacts is examined in detail. The ideas involved include (1) the double-blind hypothesis for schizophrenia, (2) the critique of game theory from the viewpoint of anthropology and psychiatry, and (3) the application of concepts of communication theory and theory of logical types to an interpretation of psychoanalytic practice. The protagonists of the interchange are Gregory Bateson and the two mathematicians Norbert Wiener and John von Neumann; the date, March 1946. This interchange and its sequels are described. While the interchanges between Bateson and Wiener were fruitful, those between Bateson and von Neumann were much less so. The latter two held conflicting premises concerning what is significant in science; Bateson's and Wiener's were compatible. In 1946, Wiener suggested that information and communication might be appropriate central concepts for psychoanalytic theory--a vague general idea which Bateson (with Ruesch) related to contemporary clinical practice. For Bateson, Wiener, and von Neumann, the cross-disciplinary interactions foreshadowed a shift in activities and new roles in society, to which the post World War II period was conducive. Von Neumann became a high-level government advisor; Wiener, an interpreter of science and technology for the general public; and Bateson a counter-culture figure. 相似文献

Skin conductance responses were examined bilaterally in a group of 14 normal subjects. Twelve of them were right-handed and two were left-handed. All right-handed subjects exhibited asymmetry in skin conductance level and in skin conductance response during verbal-numerical and visual-imagery tasks. With the visual activity, larger responses were found in the left hand, while during the verbal task, larger responses were recorded from the right hand. The results were interpreted as evidence of hemispheric asymmetry of the electrodermal activity orienting response control mechanisms. More ipsilateral control for the right hand is predicted. 相似文献

An investigation of the effects of a seven-day camp experience with disturbed adolescents on approximately sixty undergraduate "camp counselors" was conducted. Measures of the types of reinforcement preferred and used as well as an overall attitude toward disturbed adolescents were obtained and evaluated. The results indicated that the student counselors did not use the type of reinforcement that they felt was most important and they did not change their attitudes toward disturbed adolescents as a result of experience. The limitations of the study are discussed as well as some suggestions for future research into practicum sites for programs training teachers of the severely disturbed. 相似文献

On the basis of cybernetic models of speech it was hypothesized that “stuttering” induced by delayed auditory feedback could be significantly reduced if the Ss were provided with an alternate input to which they could attend. The results of the experiment supported the hypothesis. The possible implications for the treatment stuttering are discussed. 相似文献

The investigation analyzed the phonemic paraphasic errors of 10 asphasic patients with posterior cerebral lesions. The results indicated that paraphasic speech is characterized by complex confusions, often occurring at the ends of words and often involving phonemic transpositions. Many of the unusual and unexpected phonemic errors appeared to be due to simultaneous semantic and phonologic confusions. 相似文献

Four mentally retarded adolescents who showed little or no expressive or receptive language were given a series of tests to determine if they could respond to meaningful nonlinguistic sounds. The tests required the subjects to respond to sounds on the basis of meaning by classifying the sounds according to the objects which produced them, i.e., the sound sources. The results show that the subject could not classify the sounds on the basis of their source although they could discriminate between them. These results are in contrast to the near perfect classification by another retarded subject who lacked speech due to a motor disorder but, nevertheless, showed good understanding of language. The finding that some nonverbal children have difficulty in responding to the meaning of nonlinguistic sounds suggests the possibility that the failure of these children to develop language may have been due to an agnosia not unlike that found in adult stroke patients. 相似文献
