In this paper I attempt to show that subjectivity, as an input to the creative core of physics, is a misunderstood, but crucial factor. Utilizing Rapaport's fundamental paper, Principles Underlying Projective Techniques which identifies the determinants of the projective technique as: 1. lack of organization, 2. undifferentiation, 3. closeness to the core of the personality, and 4. the meaning of the stimulus being unknown to the subject, a link is suggested to quantum mechanics. It is further suggested the revolutionary nature of quantum mechanics satisfies the projective criterion of the material being unorganized or unfamiliar so that the function of organization can become predominant (Rapaport 1942, p. 93). 相似文献

Previous researchers using between-subjects comparisons have found eyewitness confidence and accuracy to be only negligibly correlated. In this study, we examined the predictive power of confidence in within-subject terms. Ninety-six subjects answered, and made confidence ratings for, a series of questions about a crime they witnessed. The average between-subjects and within-subject accuracy-confidence correlations were comparably low: r = .14 (p less than .001) and r = .17 (p less than .001), respectively. Confidence is neither a useful predictor of the accuracy of a particular witness nor of the accuracy of particular statements made by the same witness. Another possible predictor of accuracy, response latency, correlated only negligibly with accuracy (r = -.09 within subjects), but more strongly with confidence (r = -.27 within subjects). This pattern was obtained for both between-subjects and within-subject comparisons. The theoretical and practical implications of these results are discussed. 相似文献

The national self-help group, Fundamentalists Anonymous (F.A.), has focused attention upon mental problems that may be caused or exacerbated by authoritarian religion. In this article we outline assertions about the mental problems caused by membership in fundamentalist religion, illustrate these with two case histories, briefly discuss intervention strategies, and describe conceptual and empirical issues. While former members have presented problems severe enough to warrant professional treatment, a causal link between their symptoms and their religious membership has not yet been established, because there is little empirical work on the subject.An earlier version of this paper was presented at the annual meeting of the American Psychological Association in New York in August 1987.The authors express gratitude to Stephen Strack, Ph.D.; Robert Meagher, Ph.D.; Herman Feifel, Ph.D.; and Ted Schoenberger, M.D., for their helpful comments on previous drafts of this paper. 相似文献

Two studies using a computer-simulated, strategy-formulation game and business students were conducted using simultaneous verbal protocols. It was found that a number of information-processing and information-evaluation thought processes were significantly related to game performance. Consistent with what is known about individual decision making, the present results suggest that, for the task used in this study, individuals who engage in causal analysis perform better than those who do not. But those who focus on negative emotions, blindly repeat previously successful decisions, and engage in illogical through processes perform more poorly than those who do not. Causal replication using real managers within organizational settings, however, is needed before firm conclusions can be drawn from this research. 相似文献

Blind readers were tested using two methods of reading text displayed by an Apple microcomputer. The first method employed an Optacon system, a device that displays tactile representations of single characters, and the second used an interactive single electronic braille cell that displayed grade 1 braille characters. The results demonstrated no difference in accuracy or reading speed between these two methods. Thus, the serial presentation of braille characters at a single position appears to be a viable method of information transfer between computers and braille readers. 相似文献
