Experiments were performed to investigate the Filehne illusion, the apparent movement of the background during pursuit eye movements. In a dark room subjects tracked a luminous target as it moved at 3°/s or 10.5/s in front of an illuminated background which was either stationary or moved at a fraction of the target speed in the same or opposite direction. Subjects reported whether the background appeared to move and the direction of the movement. Results reveal only a partial loss of position constancy for the background during tracking. The stationary background is perceived to move slightly in the direction opposite to that in which the tracked target is moving. These results seemed best described as an instance of perceptual underconstancy and led to the speculation that the source of the illusion is an underestimation of the rate of pursuit eye movements. An experimental test of this hypothesis which produced supporting evidence is reported. 相似文献

The purpose of this study was to investigate the relationship of levels of vocational decidedness and the satisfaction or dissatisfaction of one's level of vocational decidedness with dogmatism and self-esteem. The results indicated that vocationally decided and undecided subjects represent uniquely different populations on measures of dogmatism and self-esteem. 相似文献

This study investigated reasoning with abstract conditional sentences as a function of age. Subjects from third-grade to eleventh-grade were required to evaluate the conclusion of several conditional arguments. The results confirmed the previously established finding that performance improves with age, particularly between 11 and 15 years. This finding could be interpreted to indicate that individuals become more logical as they get older. However, another possible interpretation is that the meaning of a conditional sentence like pthenq for naive Ss may not always be given by the truth function pq true, false, true, and true. Further analysis suggested that at 9 years individuals treat the connective in the sentence, ifpthenq, as if it were either a conjunctive or a biconditional, that the conjunctive meaning disappears with increasing age and after 13 years is gradually superceded by the conditional. 相似文献

This study examined the role of socialization experiences in the development of psychological differentiation. In each of three countries (Holland, Italy, Mexico) two villages were selected as presenting a contrasting picture with regard to degree of emphasis on conformity to family, religious and political authority. It was hypothesized that within the pair of villages in each country children from the village which stressed social conformity would tend to be more field dependent and show other signs of less developed differentiation than children from the village in which social conformity was less emphasized. In each of the six villages approximately 100 children (boys and girls, aged 9–11 and 13–15) were studied. Differentiation was assessed by a battery of tests of field-dependence-independence and the figure-drawing test. In every comparison of mean test scores between pairs of villages, in each of the three countries, children from the village in which social conformity was stressed obtained scores reflecting less differentiated functioning. Village differences were significant for every measure of differentiation in all three countries. Addition alanalyses of the data from the tests of differentiation and other tests used yielded results essentially consistent with findings from previous studies. 相似文献

Summary Inductivism is understood as the explication of the degree of confirmation as conditional logical probability. Inductivism is not recommendable in the form of Carnap's -system, but tenable in the form of Bayesianism. Objections directed at it are either irrelevant or can be taken account of within Bayesianism. 相似文献

Educable adolescent male retardates were compared with normal males of equal CA and equal MA on a visual backward masking task. Significantly shorter interstimulus intervals were required to induce a masking effect in the equal-CA group than in the retarded and equal-MA groups, who did not differ from each other. Speed of visual processing is a function of MA. It is related to CA in normals. and to IQ when retardates are compared with equal-CA normals. 相似文献

Perception and encoding of item-information about the occurrence of simple, well-known events (numbers) for retrieval by either same-order recall or serial-order recall was investigated by specifying kind of recall to be used either before or after perception and encoding. Both same-order and serial-order recall were less when kind of recall was specified after presentation, but serial-order recall decreased more than same-order recall. These results indicate that the same numbers may be perceived differently for same-order or serial-order recall: different kinds of item-information may be encoded either in terms of presentation characteristics (serial position for same-order recall) or event characteristics (ordinal position for serial-order recall). 相似文献

The dynamics of individual resistance in group psychotherapy are described under two classifications: 1) extragroup-session resistance, and 2) intragroup-session resistance. The different kinds of resistances in each classification are explained and examples from group sessions are given to demonstrate each.The author acknowledges with thanks the editorial assistance and suggestions made by Aaron Stein, M.D., F.A.G.P.A., Clinical Professor, The Mount Sinai School of Medicine, C.U.N.Y., and Attending in Charge, Group Psychotherapy Division, Department of Psychiatry, The Mount Sinai Hospital, New York. 相似文献

Attempts are made to transform the basis of elementary probability theory into the logical calculus.We obtain the propositional calculus NP by a naive approach. As rules of transformation, NP has rules of the classical propositional logic (for events), rules of the ukasiewicz logic
0 (for probabilities) and axioms of probability theory, in the form of rules of inference. We prove equivalence of NP with a fragmentary probability theory, in which one may only add and subtract probabilities.The second calculus MP is a usual modal propositional calculus. It has the modal rules x x, x y x y, x x, x y (y x), (y x), in addition to the rules of classical propositional logic. One may read x as x is probable. Imbeddings of NP and of
0 into MP are given.The third calculus P is a modal extension of
0. It may be obtained by adding the rule ((xy)y) xy to the modal logic of quantum mechanics Q [5]. One may read x in P as x is observed. An imbedding of NP into P is given. 相似文献

This study employed a series of sorting tasks with 22 normal and 20 children with behavioral disorders (BD) to determine whether BD children discriminate among three classes of social actions viewed by normal children as distinct. These categories are (1) the moral (actions having intrinsic effects upon the rights or well-being of others), (2) the conventional (actions whose propriety is determined by social consensus), and (3) the personal (actions whose propriety is a matter of individual prerogative). Findings were that although BD children distinguished among the three forms of behavior, they differed with normals in the classifications of specific acts and in the reasons given for act classifications. Chief among these differences was the finding that BD children were less likely than normals to identify acts as within their personal domain.We wish to thank Mary Confray, Denise Jaffe, and Christopher Pellikan for their help with the data collection. Thanks are also due to Diana Algminas of the Proviso Area Exceptional Children's Program, Ted Lawrence of the West Suburban Association for Special Education, and Wayne Thorne of the Board of Education District No. 89 (Maywood and Melrose Park, Illinois) for the cooperation of schools in their respective districts. We wish also to thank Mark Oberlander and Ronald Brown for their suggestions regarding identification of the BD sample. Portions of these data were presented at the annual meeting of the American Educational Research Association, Los Angeles, April 1981. 相似文献
