In three experiments, the effect of target luminance on estimates of visual persistence was determined on a popular successive-field task. Even though the experiments differed from each other only in terms of minor changes in stimulus conditions, very different effects were obtained across the three experiments. The different findings were attributed to the often overlooked roles of masking and target degradation on tasks of persistence. Implications for the numerous contradictory findings in the persistence literature are discussed, and the current popularity of the successive-field task is questioned.  相似文献

Subjects studied 12-word lists for free recall. During presentation of the lists, each word was followed by a supraspan sequence of digits, which the subjects tried to reproduce. This task, unlike those used in previous research with this continual distractor procedure, presumably taxed immediate memory capacity to the full. Nevertheless, the word recall data showed a pronounced recency effect. Moreover, the magnitude of the recency effect was found to be just as great with this task as with a more typical task in which the demands on immediate memory are likely to be fewer. These findings reinforce the emerging view that the recency effect need not be the product of immediate memory.  相似文献

Psychoanalysis has never developed a tradition of systematic followup study to evaluate outcome and to improve technique and theory for a variety of reasons, partly theoretical, stemming from the conception of the unfolding transference neurosis and its analytic resolution as the precondition for cure, and partly historical, having to do with the happenstance of its development as a private practice-based discipline and training outside of the academic setting. Freud, however, was never bound by such strictures and published whatever post-treatment data he acquired on all his best-known case histories. But following Freud most analysts, with some notable exceptions, eschewed followup activity as unanalytic. It is this tradition that more recent studies like those of Pfeffer in New York and the Psychotherapy Research Project of The Menninger Foundation in Topeka have squarely challenged. Data are presented from the Menninger project dealing specifically with the impact of routine planned followup on issues of treatment termination and resolution and on the nature of the post-treatment period. The degree and kind of patient cooperation with the followup inquiry, the impact of followup on treatment termination and resolution (both impeding and facilitating), and the role of followup intervention in relation to return to formal post-treatment therapy (or consolidating against it), are all discussed.  相似文献

This article discusses risk behaviors, seemingly voluntary actions of individuals that have adverse health consequences. The central theme is to examine these behaviors from two contrasting perspectives, that of the individual and that of the population as a whole. It is argued that distinguishing between individual and population views is important for understanding and interpreting health risk data, for developing conceptual and theoretical models for explaining these behaviors, and for devising intervention strategies to modify them. It is argued that an appreciation of both the individual and the population perspectives is important to developing effective action strategies for reducing these behaviors as public health problems.  相似文献

The purpose of this investigation was to determine if there were differences between regular education and emotionally disturbed early adolescents with respect to self-concept, body image, and selected uses of clothing. A questionnaire was administered to 74 regular education students from three middle schools. An additional 27 students labeled emotionally disturbed were surveyed from one of the schools. The questionnaire contained existing measures of self-concept and body cathexis and a revised clothing scale developed by the authors. Analysis of the data using t tests revealed significant differences between the groups with regard to self-concept and body image. In both cases, regular education students perceived themselves more positively than did those labeled emotionally disturbed. Factor analysis of the clothing-use measure gave rise to five distinct factors, one of which revealed a significant difference between the groups when analyzed by t tests. This factor, "dependence," examined the emotional effects of the use of clothing on individuals, such as the ability to influence mood. The emotionally disturbed students were less likely to use clothing to influence mood than were the regular education students. The results of this investigation lend further credence to the importance of self-concept in the education curriculum, and imply that the usual aspects of the curriculum that deal with self-concept may be served better by helping the individual become more realistic and self-accepting. The use of clothing as a tool to enhance self-concept merits further investigation.  相似文献

Two profit-making industries, nursing homes and board-and-care homes, care for about one million chronic mental patients. This care is primarily custodial and probably not very different from the care patients received in the public sector prior to deinstitutionalization. Moreover, certain characteristics of privately owned facilities encourage poor patient care so as to maximize profit. The problem could be ameliorated if chronic mental patients were strong and informed consumers or if the public sector strongly regulated proprietary care. However, neither of these two conditions now hold. Perhaps the apparent difficulties in significantly improving care for chronically mentally ill individuals despite seemingly major changes in policy reflect a fundamental problem in overall social policy--a reluctance to care for chronically indigent individuals of all kinds.  相似文献

This study investigated the relationship between occult participation, substance abuse, and level of self-esteem in adolescents. Data were collected from 50 adolescents who ranged in age from 12 to 19 years and who spoke English as their primary language. The combined group of adolescents consisted of 25 clinical and 25 nonclinical youth. Participants completed a three-part questionnaire package which included Rosenberg's Self-Esteem Scale, the Adolescent Magic Questionnaire, and the Drug and Alcohol Assessment Scale. Results indicated that adolescent substance abuse and occult participation were significantly related. High and low occult participation groups were determined, and significant differences were found between the high versus low occult groups when compared on the primary variables of self-esteem and substance abuse. Significant differences were also noted when comparing the high versus low occult groups with various psychosocial developmental variables. Included is a discussion of the impact of occult participation on the psychosocial elements of adolescent self-esteem, self-concept, tolerance for deviance, and religious involvement.  相似文献
