Analysis of oral and written discourse suggested differing cognitive demands for modes of expression. Verbal samples were provided by 8 adolescents with closed head injury (CHI) and 8 controls. A generation task using a picture stimulus was the basis for discourse. Eight measures [productivity, efficiency, semantic ties (lexical, incomplete, elliptical), maze use, coherence (global, local)] were utilized. A covariate model consisting of group membership (CHI vs control), executive functioning and working memory helps to explain variance in the discourse skills of adolescents with CHI. 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

Many have suggested that complementary gender stereotypes of men as agentic (but not communal) and women as communal (but not agentic) serve to increase system justification, but direct experimental support has been lacking. The authors exposed people to specific types of gender-related beliefs and subsequently asked them to complete measures of gender-specific or diffuse system justification. In Studies 1 and 2, activating (a) communal or complementary (communal + agentic) gender stereotypes or (b) benevolent or complementary (benevolent + hostile) sexist items increased support for the status quo among women. In Study 3, activating stereotypes of men as agentic also increased system justification among men and women, but only when women's characteristics were associated with higher status. Results suggest that complementary stereotypes psychologically offset the one-sided advantage of any single group and contribute to an image of society in which everyone benefits through a balanced dispersion of benefits. 相似文献
