This paper explores the significance of Marie Bonaparte's book, Topsy: The Story of a Golden Haired Chow. The manifest importance of Topsy has been attached to the fact that the Freuds translated it out of gratitude to Bonaparte and because of their love for dogs. Another level of significance emerges when the book is placed in historical context. Topsy elucidates the relationships between Marie Bonaparte, Sigmund Freud, and Anna Freud. It reflects Bonaparte's feelings about Freud's illness and is part of an ongoing dialogue with him. The persistent misplaced emphasis on the "dog story" has obscured the more profound issues. The author suggests that the conflicting needs to appreciate transience and to avoid mourning may account for both the importance of the book and for its obscurity. 相似文献

Qualitative studies have noted that individuals with "borderline" psychopathology exhibit extreme thought disorder on unstructured tests, yet manifest relatively normal performance on more structured tests of cognitive performance. The present study provides empirical support for this clinical observation. Borderline syndrome patients, defined by DSM-III criteria for borderline personality disorder and/or schizotypal personality disorder, demonstrated significantly greater thought disorder on the Rorschach, as measured by Johnston and Holzman's (1979) Thought Disorder Index (TDI), than did nonpsychiatric controls and were indistinguishable from patients with schizophrenic disorder of relatively recent onset. Borderline patients did not differ from controls on a structured test of cognitive slippage. Further examination of the role of structure in the assessment and treatment of borderline syndrome disorders seems warranted. 相似文献

This article deals with appropriate communication and interpersonal skills that nurses may use in order to support patients who are experiencing self-concept changes related to their health problems. Three areas of patient need related to self-concept are explored. The stages of adaptation to loss and the crucial task of grief work are reviewed, and nursing interventions designed to strengthen the self-concept and support patients as they adapt to loss are suggested. Sensitive communication, although a low-visibility nursing skill, is cited as critical in assisting the patient to achieve an optimum level of wellness. 相似文献

The proliferation of computer-generated psychological reports prompts an examination of the presuppositions of such reports and what they offer in the way of understanding individual clients. This topic is approached primarily through a review of some basics of psychological testing and psychological assessment. Major differences are noted between these two approaches to evaluating clients: They are different processes, and they yield different products. Assessment is a complex set of activities that seeks solutions to specific problems, whereas testing fits a straightforward actuarial paradigm. Testing is readily adapted to an automated data processing system, whereas the complex of assessment procedures cannot be so managed. Serious questions about the validity of computer reports are raised, however, and ethical concerns are expressed over the use of these reports by persons without adequate psychological training to understand them correctly. Limited uses for computer reports are suggested along with the need for further studies of validity and ethics. 相似文献

Three methods for estimating reliability are studied within the context of nonparametric item response theory. Two were proposed originally by Mokken (1971) and a third is developed in this paper. Using a Monte Carlo strategy, these three estimation methods are compared with four classical lower bounds to reliability. Finally, recommendations are given concerning the use of these estimation methods.The authors are grateful for constructive comments from the reviewers and from Charles Lewis. 相似文献

Temporal contrast sensitivity for counterphase flicker was determined for specifically disabled and normal readers to investigate whether the two groups differ in the functioning of their transient systems. In experiment 1, temporal contrast sensitivity was measured over a range of temporal frequencies with a spatial frequency of 2 cycles deg-1. Disabled readers were less sensitive than the control subjects at all temporal frequencies. In experiment 2, temporal contrast sensitivity was measured at a temporal frequency of 20 Hz over a range of spatial frequencies. Disabled readers were less sensitive than the controls at all spatial frequencies, with the differences between the groups increasing as spatial frequency increased. Both these findings are interpreted as supporting the hypothesis of a transient-system deficit in the visual systems of disabled readers. 相似文献

Randomly scheduled spot observations of 83 zero to six-year-old American middle-class children were used to investigate factors affecting the development of sex differences in young children's activities in and near their home. Sex and age differences in children's typical play and nonplay activities and in the people with whom they did activities were examined. The results showed that there were fewer sex differences in children's activities, activity partners, and general social settings than expected. Girls spent more time engaged in housework and school-related activities than boys, while boys spent more time in social gross motor play with other children and in self-care activities than girls. Children spent a surprisingly large amount of their time with members of their immediate family — particularly their mother and one other sibling. Boys and girls did not differ, however, in the time they were in settings or doing activities with their father, with their mother, or with same-or mixed-sex child groups.This research was supported by an award to the author from the Wisconsin Alumnae Research Foundation at the University of Wisconsin — Madison. The author would also like to acknowledge the research and editorial assistance of Daniel J. Walsh. In addition, Aletha Huston, Beatrice B. Whiting, and Gary G. Price provided valuable advice on this and earlier versions of this paper. 相似文献
