Repressers and Sensitizers viewed tachistoscopically presented TAT transparencies under conditions of high and low bogus physiological feedback. As predicted, during high bogus physiological feedback, Repressers showed a significant increase and Sensitizers showed a significant decrease in response thresholds. These results serve to extend the validity of bogus physiological feedback procedures in the analog investigation of emotion and offer theoretical implications relevant to the areas of personality, emotion, psychophysiology, and psychopathology. 相似文献

Proprioception is often considered to be critically involved in producing adaptation to a prism-induced visual displacement. The present study focused on reduction of proprioceptive feedback during prism exposure by means of hypnotically induced anesthesia in the adapting arm. In addition, intermanual transfer was considered. Results showed adaptation occurring in situations where S could feel arm sensations while viewing arm movement during a prism exposure. However, if the adapting arm was hypnotically anesthetized while still remaining mobile, adaptation did not occur. No intermanual transfer was found between the adapted arm and the unadapted arm. 相似文献

Twelve mentally-defective schoolboys between 14 and 16 years of age took an intelligence test (AH 4) once a week, ten times. They took also Progressive Matrices once, after they had finished the AH 4 testing. Subjects of low intelligence were chosen in order to throw some light on the findings of a previous experiment on repeated retesting, in which the subjects were intelligent adults. The main aims of the schoolboy enquiry were to ascertain how far the flattening of the progress curves observed in the earlier enquiry was due to the artificial “ceiling” imposed and how far the part played by variation within the individuals varies with the level of intelligence of the group.
The mentally-defective subjects showed a gradual improvement in test performance with little sign of flattening towards the end; their individual progress curves were far less smooth than had been those of the more intelligent subjects. Other findings included relatively high proficiency on the diagrammatic part of the test, as opposed to the verbal and numerical, and some transfer of training from AH 4 to Progressive Matrices. 相似文献

Right isosceles triangles, which differed in size and orientation, were presented in a sequential visual recognition task. Subjects produced an identity match response if the first self-presented stimulus, now in memory, was identical to a sequentially presented stimulus and a nonidentity match response if the subsequently presented stimulus differed in either or both size and orientation. The pattern of nonidentity recognition reaction times produced was compared to predicted patterns deduced from several theories of form information processing. The pattern of responses for both group and individual data were better described by serial and parallel self-terminating models with probabilistic assumptions than they were by template or deterministic serial or parallel models. A second study, in which identity and nonidentity response bias was equated, found that the identity responses were significantly faster than nonidentity responses, supporting wholistic processing for the identity matches and, when combined with the nonidentity match results, supporting a dual process theory. 相似文献

Duration, direction-change frequency, and color-change frequency of an induced afterimage were investigated as a function of iris pigmentation (blue or brown) and the wavelength of a light pulse used to bleach retinal photoreceptors. For blue-irised subjects, a yellow (Wratten 9) pulse produced the longest enduring afterimage while a blue-green (Wratten 44A) pulse produced the shortest enduring afterimage. The reverse was true for brown-irised subjects. Neither of the other dependent measures was affected by iris pigmentation or by pulse color. The afterimage duration results were explained in terms of the possible role of the iris in selectively and differentially filtering various wavelengths of light as a function of its pigmentation. 相似文献

Drawing on a conception of scientists and community members as partners in the construction of ethically responsible research practices, this article urges investigators to seek the perspectives of teenagers and parents in evaluating the personal and political costs and benefits of research on adolescent risk behaviors. Content analysis of focus group discussions involving over 100 parents and teenagers from diverse ethnic and socioeconomic backgrounds revealed community opinions regarding the scientific merit, social value, racial bias, and participant and group harms and benefits associated with surveys, informant reports, intervention studies, blood sampling, and genetic research on youth problems. Participants comments highlight new directions for socially responsible research. 相似文献
