The displacement of the images on the retina that results from a turning of the eye does not lead to an apparent motion of what is seen, It has been generally assumed that this is due to a compensating process which takes eye movement into account and serves to discount those image displacements that result from eye movements, It follows from this view that an abnormal image displacement, that is, an image displacement that is larger or smaller than the causing eye movement would warrant, should lead to an experienced displacement of the target. Abnormal image displacement was produced by placing the eye in the converging or diverging bundle of rays from a point source that form behind a strong positive lens; this arrangement yielded a disc-shaped image, the projection of the pupil onto the retina, which displaced abnormally during eye movements. By changing the position of the eye along the axis of the lens in relation to the crossing point of the bundle, the degree to which the displacement was abnormal could be varied, For various displacement rates ranging from 25% to 120 and 400% of normal, abnormal displacements produced by incidental eye movements remained unnoticed, Only where eye movements were intentional did some of our Ss report shifts of the perceived image. It is suggested that the organism copes with the image displacement resulting from the ever-present incidental eye movements not by compensation but by ignoring them. 相似文献

This article reviews evidence regarding contributions of neuropsychiatric and psychological vulnerabilities to violent delinquency, and the interaction between intrinsic vulnerabilities and experiential factors in the genesis of antisocial juvenile behavior. Consideration is given to biochemical and physiological factors, genetics, medical status, and neurological, psychiatric, and neuropsychological factors. Implications for treatment are discussed. 相似文献

The GRW theory is a recent attempt to solve the measurement problem in quantum mechanics, and the tails problem is a well-known and potentially fatal criticism of the GRW theory. The first half of the paper is an exposition of the measurement problem, the GRW theory, and the tails problem. In the remainder of the paper, two methods of dealing with the tails problem are considered: first, altering the GRW theory so as to avoid the tails problem; and second, denying that the tails problem is more than a novel aspect of a universal vagueness in the way scientific theories relate to everyday language. 相似文献

Group therapy investigations are often conducted by researchers rather than by experienced clinicians who also possess research expertise. Given the fact that doctorally prepared clinicians must demonstrate research competence in their education programs, it is surprising that there is not more research on group therapy. The literature indicates that research and group psychotherapy practice are considered quite separate entities. However, there is much that both processes have in common. The principal investigator's experience during a group psychotherapy research project suggested that the conflict between the roles of researcher and clinician may not be due to differences in the external processes but rather to difficulties in trying to combine them within one person. The value of the researcher-clinician is elaborated, and recommendations are offered.This paper was supported by a grant from the Group Psychotherapy Foundation. 相似文献

This study examined 10 factors and their relation to the life satisfaction of single middle-aged professional women. The proposed regression model, which included job satisfaction, gender identity, locus of control, social support, health, financial resources, leisure-time activities, sexual satisfaction, and regrets regarding life circumstances, was explored through a questionnaire. Questionnaires were administered to single professional women in higher education institutions. Responses were received from 152 women. Performance on life satisfaction was significantly explained by recourse to the variables of job satisfaction, internal locus of control, regrets regarding life circumstances, sexual satisfaction, and leisure-time activities. 相似文献
