Visual cognitive differences between hearing (N = 16) and deaf (N = 32) high-school and middle-school students were studied. Visual tasks were presented on a microcomputer and response latencies were collected. Significant differences were noted between the deaf and normal groups but not between total communication deaf and oral deaf students. These differences support the hypothesis that deaf students prefer a visual cognitive strategy. Implications for educating the deaf are discussed.  相似文献

The Rosenberg Self-esteem Scale was administered to 550 14- and 16-yr.-old (+/- 6 mo.) girls. Self-esteem scores were categorized by weight and weight by height. Scores on the Quetelet Index for obesity were correlated with self-esteem scores. Mean self-esteem of the low- and middle-weight by height group was significantly higher than the mean of the high-weight by height group. In analyzing weight alone, the self-esteem of the middle-weight group was significantly higher than the self-esteem of the high-weight group. The correlation of the obesity index and self-esteem indicated that as weight increased self-esteem decreased.  相似文献

Observations on three children with neurolisteriosis (one case of meningitis, two cases of meningoencephalitis, each Serovar 4 b), show that even after the neonatal period, listeriosis must not be ignored in the process of diagnosis and therapy. It is the bacteriological examination of the cerebrospinal fluid, together with the blood culture, and not clinical symptoms and serology that guarantee a timely diagnosis and therapy (ampicillin and gentamicin).  相似文献

Insight reflects the unitary nature of psychic activity in contrast to the fragmentation created in abstracting categories for the purpose of study and discussion. The unique analytic clinical dyad offers a structure in which intrapsychic fragments can be actualized and integrated. As a result, the analyst's contribution is more crucially one of exploration than of revelation. Whatever the area of examination, past or present, the link to analytic immediacy offers the opportunity to make meanings meaningful, to convert known facts to psychic truths. The analyst's clinical task requires his private self-analysis as part of the collaborative exploration of how the patient's mind works. Higher level ego functioning, including acutely active remembering, is at times transiently loosened in order for the analyst to share in the clinical work of discovery. The words the analyst uses to communicate his understanding convey only approximate manifest meanings, though they structurally reveal deeper messages of importance to the patient. These verbal approximations help stimulate self-reflection in the analysand as a step in the process of gaining insight.  相似文献

A plate-pushing task was used to measure endogenous pain in the wrist from different loci. Practical application in rehabilitation seems reasonable.  相似文献

This paper provides a review of recent Supreme Court decisions stemming from the implementation of voluntary AAPs that include preferential treatment as a remedy; the evidence and proof required to establish and defend against reverse discrimination claims is identified. Overall, the courts sanctioned the use of preferential treatment if it occured as part of a well-conceived AAP. However, differences were found in the manner in which the courts adjudicated Title VII and constitutional claims of preferential treatment. The discussion examines research on the potential effects of voluntary AAPs on important organizational and societal outcome variables. We conclude that the impact of AAPs is likely to be far-reaching, exerting an effect possibly well beyond the limits considered in court decisions.  相似文献

Summary The distinction is drawn between the metatheoretical commitments of Gestalt theory and their instantiations in explicit theory. It is argued that the metatheoretical commitments of Gestalt theory reflect important insights which might have served as the foundation of a theory of perception that avoids a number of the major difficulties associated with constructivism and the theory of direct perception. For this reason rehabilitation of the reputation of Gestalt theory is urged. In the concluding section certain similarities between the foundational premises of Gestalt theory and parallel distributed processing approaches are noted.The contents of this paper were presented initially at a symposium on perceptual theory in honor of Irvin Rock which convened in Washington, DC, on the occasion of the 1986 meetings of the American Psychological Association  相似文献
