Corrections for restriction in range due to explicit selection assume the linearity of regression and homoscedastic array variances. This paper develops a theoretical framework in which the effects of some common forms of violation of these assumptions on the estimation of the unrestricted correlation can be investigated. Simple expressions are derived for both the restricted and corrected correlations in terms of the target (unrestricted) correlation in these situations.The author is grateful to D. Holt, C. J. Skinner and T. M. F. Smith (all University of Southampton) for their helpful comments. Research was initially supported by grant No. HR7152 from the Economic and Social Research Council. 相似文献

The study was conducted to determine, first, whether it is the deep or the surface clause that is more important as a speech planning unit, and second, whether syntactic decisions are made during sentence production. Subjects, while talking, heard tones to which they had to respond by pressing a button; reaction times to these tones were taken as an index of processing load during production. It was found that there were increased RTs at the ends compared with the beginnings of deep structure clauses. No difference was found between RTs at the beginnings and ends of surface clauses not corresponding to a deep clause. The results were interpreted as showing that deep clauses are major planning units and that some planning for clauses occurs at the end of the preceding clause. Differences were found between RTs during clauses of different syntactic structure. These results were interpreted as indicating that syntax influences production and were discussed in relation to previous studies of pausing and speech disruption. 相似文献

Subjects in a threat condition were informed that they had failed an important test while subjects in a nonthreat condition were not told that they had failed. To manipulate the use and timing of coping strategies for dealing with threat, subjects were told to (a) redefine the nature and importance of the test before receiving feedback, (b) redefine the nature and importance of the test after feedback, or (c) estimate the performance of their friends on the test (i.e., project) after receiving feedback. Repeated measures of subjective anxiety and pulse rate indicated that (a) the threat manipulation was effective in increasing stress, (b) redefinition occurring before the onset of threat was effective in eliminating stress, and (c) redefinition occuring after the onset of threat was ineffective in reducing stress. Projection reduced the report of subjective anxiety. The results revealed factors that influence coping strategy effectiveness and resolved conflicts in previous findings. 相似文献

Jeremy Holmes 《Journal of Family Therapy》1983,5(3):235-251
Freud's Dora case is considered from the perspective of family therapy. Her illness is homeostatic; it holds two disturbed fractured families together. Freud considered his analysis a failure; from a systems point of view it was a partial success. His challenging technique is similar to that of modern family therapists. The theories of change underlying family therapy and psychoanalysis are compared. There are many similarities. They are mutually compatible disciplines, working at different levels. 相似文献

It is argued that Freud was not, as Sulloway (1979) contends, a "crypto-biologist" of the mind, but rather a cultural anthropologist of the mind. Freud's genetic conception of the psychic apparatus was neither exclusively nor critically derived from biology. Rather, it was based on an anthropogenetic approach to the archaic heritage of mind inspired in part by the moral philosophy of Nietzsche. The idea of tragedy was the unifying theme of Freud's cultural interpretation of evolutionary psychology. The historical search for the primal origins of neurosis led Freud to the unavoidable conclusion that neurosis was in the beginning a prehistoric moral dilemma which, over the course of mental evolution, eventually evolved into guilt, discontent, and neurosis as modern-day phylogenetically endowed facts of life. Freud (1930) made it clear that the source of man's biological and cultural evolutionary progress--self-denial--was also responsible for the tragedy of the human condition, namely, repression, eternal psychic ambivalence, and chronic mental illness. He believed that neurosis began, as Nietzsche (1887) exclaimed, with the "reduction of the beast of prey 'man' to a tame and civilized animal..." (p. 42). For both Freud and Nietzsche, the cause of the human tragedy was not merely the fall from Nature, but the inexorable knowledge that Man's denial of his biological heritage was the very basis for being human. 相似文献

Speech abnormalities in seizures: a comparison of absence and partial complex seizures 总被引:4,自引:0,他引:4
In order to determine whether speech changes are useful in differentiating seizure types, a study was done in which speech abnormalities during two distinct seizure types, partial complex and absence seizures, were compared. Speech changes noted during prolonged electroencephalographic and video monitoring were compared in 16 patients with 47 partial complex seizures and 19 patients with 95 absence seizures. Speech changes were common during both seizure types. Although some significant differences in speech patterns were noted in the two seizure types, the degree of overlap was such to preclude using speech changes alone as the sole clinical criteria in differentiating the seizures. 相似文献

Two experiments investigated the effect of presenting a brief noncontingent, unsignaled shock prior to warning-signal onset on discriminated lever-press avoidance behavior in rats. The main finding was that noncontingent shock delivered 2 sec but not 16 sec prior to warning-signal onset facilitated avoidance performance and learning. These results were predicted on the basis of shock-elicited response bursting which was expected to increase the operant level of the lever-press response at short shock-warning signal intervals. It was suggested that species-specific limitations on rats' lever-press avoidance are not unconditional, but rather can be overcome with environmental manipulations. 相似文献

Eight male albino rats acquired conditioned suppression under either predictable (Estes & Skinner, 1941) or random (Rescorla, 1968) procedures. The random procedure led to more generalized suppression (non-CS suppression) and greater resistance to extinction. In addition, the pattern of responding during the CS differed: the predictable group produced negatively accelerated cumulative records during early extinction trials; the random group produced positively accelerated cumulative records. 相似文献
