It was shown that a McCollough-type color aftereffect could be induced using a pair of patterns each of which contained lines of many orientations (radial lines and concentric circles). That is, the two patterns appear to be color adapted independently. The effect could simply be a new version of the McCollough effect facilitated by a tendency to fixate the centers of the patterns. Also, the size features of the displays could be used as the basis of a spatial frequency analyzer explanation. Experimental data were used to test both of these suggestions, but very little support was found for either. It was therefore suggested that the major basis of the effect was the color adaptation of “curvature analyzers.” 相似文献

We investigated the parameters of involuntary word reading in the Stroop task in 7 experiments. Experiments 1-4 varied response modality and the presence of congruent word trials in a test of the claim that presenting a Stroop color word with only one letter in the target color eliminates the Stroop effect. Experiments 5 and 6 addressed the roles of spatial attention and orthographic processing as possible mechanisms behind the reduction of Stroop effects with the single-letter format. Experiment 7 investigated the limits of involuntary reading under optimal conditions for selective processing of rectangular color patch targets. We found that the single-letter format reduced but never eliminated Stroop effects, spatial attention but not orthographic processing plays a role in the effect of the single-letter format, and word reading is not completely prevented even with austere presentation conditions. We conclude with a defense of the involuntariness criterion for automaticity in the Stroop task, particularly when word reading is viewed in the context of a skilled performance. 相似文献

This study explored gender differences in the degree to which parent-child dyads and family system variables are associated with relationship quality in late adolescence and early adulthood. It was hypothesized that the quality of mother-child and father-child relationships, as well as family adaptability and family cohesion, would be positively correlated with the quality of intimate relationships in late adolescence and young adulthood. Further, it was hypothesized that correlations would vary according to gender. The sample was composed of 50 males and 48 females between the ages of 18 and 24. The results indicated that the relationship of family factors to the intimate relationships of young adults was similar for males and females. Specifically, a positive relationship with mother and greater adaptability in the family system during adolescence were related to more positive intimate relationships in young adulthood. 相似文献

Professionals in the fields of mental retardation and giftedness have much to teach each other as well as the field of human development in general. Examining the commonalities and differences between the fields in social issues, definitions, developmental differences from the norm, values and policy issues, and educational and long-term implications deepens insights about both normal and deviant development. The authors stress the importance of individual differences in the differential design of educational strategies and the application of approaches developed with specialized populations to normally developing children. Current social inequalities affect both of these fields in particular ways. Finally, numerous research agendas can be enhanced by including representatives of both ends of the normal curve. 相似文献

In exploring stereokinesis, we devised flat cycloidal display figures which, when rotated on a disc in the frontal plane, are perceived as illusory three-dimensional forms with movement in depth; the dominant percepts were of twisted loops with an internal writhing motion. These dominant forms could be convincingly represented by stereo pairs derived from the flat display; related forms, not seen in the illusion, could also be constructed, seeming to show a selectivity for preferred stereokinetic forms by the perceptual system. Models were made of the stereo forms; when rotated, they showed similar illusions and selectivity. We suggest that the illusions arise because some components of the real motion do not appear in the sensory field. The perceptual system accommodates for this by constructing percepts which are not necessarily veridical but do reconcile form and motion into a coherent unity. The results are discussed in relation to concepts of invariance and rigidity, and with regard to the creative response to sensory data by the perceptual system. 相似文献
