A sample of 38 schizophrenic inpatients was found to achieve significantly higher mean scores on Scale 8 of the MMPI relative to 38 schizophrenia-spectrum and 38 control patients regardless of whether K- or non-K-corrected scores were used. However, when patients were individually classified by means of a cutting score (greater than or equal to 70), only K-corrected scores accurately discriminated between schizophrenic and control patients at a statistically significant level.  相似文献

This article is intended to provide counselors with an overview of narcissism and its treatment. In the first section, dysfunctional narcissism is described, drawing on the diagnostic indicators presented in the DSM-III and the contemporary object relations theories of Heinz Kohut and Otto Kernberg. The second section focuses on counseling narcissistic clients.  相似文献

Reports of learning from 119 participants of 18 general psychodynamic groups from the 1981 and 1982 annual meetings of the Canadian Group Psychotherapy Association were investigated. Two main learning factors emerged from a factor analysis of participant ratings, learning about oneself in a small group (factor one) and learning how to be an effective leader with professional skills (factor two). Participants reported moderate to considerable learning for both factors even though the stated task of the groups did not emphasize the learning of professional skills. Relationships between several classes of variables (group, leader, demographic) and reported learning were studied. Results that were consistent with several previous investigations were found. The discovery of a participant, sex-difference finding, i.e., greater reported learning by the women, generated a number of questions that may be addressed in future investigations.This article was derived from a paper presented at the Fourth Annual Meeting of the Canadian Group Psychotherapy Association, October 27, 1983, Banff, Canada.  相似文献

Summary The feature-integration model of visual information processing (Treisman & Gelade, 1980) predicts perceptual errors based on the incorrect grouping of stimulus features in multi-element displays. Experiment 1 examined the frequency of such errors with a tachistoscopic bar probe task using letters and novel patterns with a production response. A substantial proportion of the errors did involve figures that were not present in the display but contained combinations of features which had been present. Such errors were especially prominent with novel patterns. The results with letters suggested that such responses were due to guessing, not feature migration, and this was confirmed by Experiment 2. In the second study, responses were collected for single character displays but were scored as if they had been responses to the multielement displays in Experiment 1. The results showed the same high proportion of illusory conjunction errors as the previous results and it was concluded that both results were due to guessing. Spatial confusions in the bar probe task with letters appear to involve whole characters, not character features.This research was supported by grant A-9581 from the National Science and Engineering Council of Canada to the senior author. This research was reported as a paper to the annual meeting of the Canadian Psychological Association, Toronto, 1981. Ian Morrison is now a post-doctoral fellow at the Department of Psychology, Carnegie-Mellon University.  相似文献

Abstract. Loren Eiseley is known both as a scientist and an essayist/poet. The disillusionment with science and technology among many in the late 1950s and the search for new values in the 1960s help account for Eiseley's significance as a writer. He appears to offer a solution to mankind's contemporary disillusionment by reminding that science has limits and that intuitive, nonscientific insight is valid, especially when it is complementary to scientific knowledge. The thesis of this essay is that in content and style Eiseley writes as a religious writer in the sense that he reaffirms what is necessary for humankind to be happy and even to be "saved."  相似文献

Analysis of two chimpanzees' conversations with their teacher during a tool-use training task demonstrated that chimps use lexigrams, a humanly devised visual symbol system, selectively to encode perceived variability; that is, they generally used their symbols to differentiate alternative possibilities or to represent change or novelty in a situation. In contrast, they tended to leave unsaid what was unchanging, repetitive, or the unique possibility in a situation. Perceived variability influenced not only which symbols were selected but also utterance length: A single dimension of variability in a situation leads to single-lexigram utterances; multiple dimensions are associated with multi-lexigram utterances. This pattern of results indicates that the absence of formal grammatical structure in chimp language does not imply that utterances beyond one word in length are either rote strings or imitations. The chimps' tendency to mention the variable while leaving the constant or redundant unsaid is, moreover, strong support for the position that their use of a humanly devised symbol system is more than a series of conditioned responses.  相似文献
