Eighty male and female high school students played a modified version of the Siegel and Fouraker (1960) bilateral monopoly game, designed to assess the effects of two variables upon the development of aspiration level (AL), comparison level (CL), and comparison level for alternatives (CLnlt), and the interrelationships among these three subjective-utility parameters. Magnitude of: (a) the offers made by a programmed bargaining opponent (high vs low), and (b) the alternative to the bargaining relationship (high vs low) was varied in a 2 × 2 design. Subjects receiving high offers bargained tougher, rated themselves as more satisfied with their outcomes and, in support of the hypothesis, set their AL, CL, and CLalt estimates higher than those receiving low offers. Contrary to expectation, however, AL, CL, and CLalt were set highest by subjects in the “high offer-low alternative” condition. When subjects' three subjective-utility estimates were considered in relation to one another, all condition differences disappeared. These latter findings were interpreted using notions drawn from Upshaw's (1969) variable perspective theory of judgment. 相似文献

Correlation matrix based on questionnaire item responses by 38 Czechoslovak refugees suggested that "escape nightmares" (recurrent nightmares about being back in the exhomeland, wanting to or trying to re-escape to the free world) are unrelated to postescape incidence of various stressful events (e.g., illness, job difficulties, financial problems). However, refugees who reported a greater number of the stressful events also reported a somewhat higher incidence of nightmares on themes other than escape from homeland (r = .34). 相似文献

Apraxia in a patient with atypical cerebral dominance 总被引:1,自引:0,他引:1
Steven Z. Rapcsak Leslie J. Gonzalez Rothi Kenneth M. Heilman 《Brain and cognition》1987,6(4):450-463
Liepmann postulated that the left hemisphere of right-handed persons contains the "movement formulas" that control purposeful skilled movements of the limbs on both sides of the body. Accordingly, in right-handers apraxia should follow damage to the left hemisphere, whereas right hemisphere damage should not lead to apraxia. Although this is generally true, we recently examined a right-handed man who after a right hemispheric stroke became aphasic and apraxic with his nonparalyzed right hand. Our observations suggest that the right hemisphere of this right-handed man made a critical contribution to the planning and execution of skilled movements. This case provides evidence that right-handers should not be considered a homogeneous group in terms of cerebral motor dominance and that contrary to Liepmann's postulate, hemispheric dominance for the control of skilled movements does not entirely determine handedness. 相似文献

We describe a patient with phonological alexia caused by a small hemorrhage in the posterior-inferior portion of the left temporal lobe. The lesion induced a highly selective impairment of phonological reading without concomitant oral language deficits other than anomia for objects presented in the visual and tactile modalities. We propose that an intact dorsal pathway from inferior visual association areas to Wernicke's area via the angular gyrus could mediate reading by the lexical route, while damage to a ventral pathway disrupted the patient's ability to read nonwords. We suggest further that although visually and tactually presented objects could be recognized and both verbally and nonverbally identified, they could not be named because of a disconnection from the area of word representations. 相似文献

This case report describes an unusual combination of speech and language deficits secondary to bilateral infarctions in a 62-year-old woman. The patient was administered an extensive series of speech, language, and audiologic tests and was found to exhibit a fluent aphasia in which reading and writing were extremely well preserved in comparison to auditory comprehension and oral expression, and a severe auditory agnosia. In spite of her auditory processing deficits, the patient exhibited unexpected self-monitoring ability and the capacity to form acoustic images on visual tasks. The manner in which she corrected and attempted to correct her phonemic errors, while ignoring semantic errors, suggests that different mechanisms may underlie the monitoring of these errors. 相似文献
