A veraged evoked potentials (AEP) to verbal (digits) and nonverbal (clicks) auditory stimuli were recorded from left and right temporal leads in ten right-handed Ss. With dichotic presentation, there was no significant difference in accuracy of report of the clicks heard in each ear, but significantly more digits were identified correctly from the right ear than from the left. Dichotic verbal stimuli elicited AEP whose early components were of greater amplitude, and whose later components were of shorter latency, from the left hemisphere than from the right. No consistent latency or amplitude differences were observed between AEP from the left and right hemispheres when clicks were presented dichotically. 相似文献

Little consensus or systematic research exists regarding the symptoms that constitute depersonalization and its association with affective and perceptual dysfunctions. A scale was constructed to measure depersonalization experiences reported in the literature and four items representing psychotic symptoms. Five factors representing different types of depersonalization emerged: Inauthenticity, Self-Negation, Self-Objectification, Derealization, and Body Detachment. Based on the factors, scales were constructed; these scales have internal consistency ranging from .78 to .84. Each of these factor scales was factorially distinguishable from psychosis and correlated between .48 and .58 with the Jackson and Messick (1972) Feelings of Unreality Scale, suggesting divergent and convergent validity. Inauthenticity, the most frequent and pervasive form of depersonalization experience, was best predicted by a cognitive style featuring intense, critical examination of self and others. In contrast, Self-Objectification was best predicted by thought disorganization and perceptual distortion and was experienced somewhat infrequently by relatively few subjects. All forms of depersonalization were associated with depression, except Inauthenticity. 相似文献

The relationship between neuroticism and cognitive functioning was investigated using data from a community survey of the elderly. Contrary to Pearson (1993, Personality and Individual Differences, 14, 265–266), neuroticism was related to poorer performance on a number of cognitive measures, but the pattern of correlations differed between men and women. For men there were correlations with a dementia screening test and with tests of episodic memory and fluid intelligence, while for women there were correlations with reaction time measures. It is hypothesized that correlations with neuroticism reflect the effect of chronic stress on cognitive ageing. 相似文献

Several studies were conducted examining the influence of the use of photographs of a needy individual on a charity appeal for either a well-known or lesser-known charity organization. Results of an initial study indicated that people expected the use of a photograph to enhance the effectiveness of a door-to-door solicitation campaign and that a well-known charity would fare better than a lesser-known one in its efforts. Results of two subsequent studies involving door-to-door solicitations, however. indicated that the proportion of people contributing and the average amount contributed was not dependent upon either the photograph or familiarity with the charity. A final study using a passive countertop solicitation in stores did result in greater contributions when the photograph was present, whereas there was no difference due to charity familiarity. These findings are discussed in terms of image-maintenance concerns and social pressures associated with the immediacy of a request. 相似文献

Summary In two experiments, young subjects, healthy elderly subjects (spouses), and highly intelligent elderly subjects (elite elderly), were compared with dementia patients in a variety of explicit and implicit memory tasks, to investigate two issues: whether priming in Alzheimer-type dementia is contingent upon the presence of pre-existing representations, and whether intelligence modulates performance in explicit memory tasks in healthy ageing. Dementia patients performed as well as spouses in a homophone-spelling task. Moreover, they established new contextual associations when memory was tested by word-stem completion. The hypothesis that priming in dementia is contingent upon pre-existing memory representations was not supported. Spouses, elite elderly, and young subjects did not differ in their ability to recognize correctly recently heard stimuli or to complete word stems. However, recall of lists of words and paired associates was better in both young and elite elderly subjects than in spouses. It is concluded that intellectual capacity rather than chronological age in healthy subjects modulates performance in explicit-memory tasks.Now at The Social Psychiatry Unit, Australian National University, Canberra, ACT, Australia 相似文献

In order to facilitate garment and pattern construction, a research which involved taking a minimum of fifty-five measurements on several thousand women was conducted by the Bureau of Home Economics. Partial correlations with age held constant were computed for a representative group of 4,128 of the women. The correlations among twenty-nine of these variables served as the basis of the present study. By a combination of the multiple-group and the centroid method of factoring, five factors were extracted. After twenty-nine rotations, simple structure was evident, and the factors were interpreted as bone length, size of joints, circumference below the waist, circumference of extremities, and circumference above the waist. The intercorrelations of the primaries were computed, and two second-order factors were extracted. One of these seems to be primarily related to the growth of fatty tissue and the other to the development of the bones.The author wishes to express her appreciation to Professor L. L. Thurstone and to the members of the Psychometric Laboratory Staff for advice relative to this study. 相似文献

A lexical decision task was used in a paradigm testing the effects of sleep loss and fatigue on performance during a 72-h period of sleep deprivation. The data were partitioned into categories of response lapses, response accuracy, and the signal detection measures of discriminability (d’) and bias (β). Response lapses increased as a function of sleep loss and were fitted best by a composite equation with a major linear component and a minor rhythmic component. Response accuracy decreased as a function of sleep loss, with the rate of decrease being greater for nonwords than for words. Although d’ was higher for right visual field (RVF), it decreased for both fields almost linearly as a function of sleep deprivation. The rate of decrease for RVF stimulation was greater than for left visual field (LVF) stimulation, β did not change monotonically as a function of sleep loss, but showed strong circadian rhythmicity, indicating that it was not differentially affected by sleep loss per se. 相似文献
