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

The author outlines his clinical observations during the "middle game" of psychoanalysis, leading to recognition that structural change is taking place. "Middle game," "structure," process, and content are defined and critically discussed. Illustrative clinical vignettes are offered. The presentation emphasizes the importance of an active and resolving transference "struggle"; in addition, more traditionally noted criteria are briefly touched on, e.g., development of observing ego and treatment alliance, changes in dream function and communication, and the reviewing of the neurosis and transference during the termination phase as instances of mourning and working through. The concept of optimal psychobiological function in the service of a homeostatic principle is discussed. 相似文献

Concepts and conceptual structure 总被引:16,自引:0,他引:16
D L Medin 《The American psychologist》1989,44(12):1469-1481
Research and theory on categorization and conceptual structure have recently undergone two major shifts. The first shift is from the assumption that concepts have defining properties (the classical view) to the idea that concept representations may be based on properties that are only characteristic or typical of category examples (the probabilistic view). Both the probabilistic view and the classical view assume that categorization is driven by similarity relations. A major problem with describing category structure in terms of similarity is that the notion of similarity is too unconstrained to give an account of conceptual coherence. The second major shift is from the idea that concepts are organized by similarity to the idea that concepts are organized around theories. In this article, the evidence and rationale associated with these shifts are described, and one means of integrating similarity-based and theory-driven categorization is outlined. 相似文献

Through the use of participant observations and the collection of standardized psychological test scores from a sample of 56 street children, their characteristics were examined. The Kohs Block Design measured their intelligence; the Human Figure Drawing and the Bender-Gestalt tests were used to measure emotional and neurological functioning. The data indicated that their mental health was adequate, which is postulated to be the result of intense friendships between the children. Two different styles of street life are presented--the gamines and chupagruesos. Because of their public lives and because they live without parental supervision, their developmental periods have been altered. The paper illustrates how child development is dependent on societal reactions to aberrant children. 相似文献

The development of self-consciousness and its relationship to emotional disturbance was examined in early and late adolescence. The Imaginary Audience Scale was administered to emotionally disturbed and nondisturbed adolescents. As predicted, results indicated that self-consciousness decreased with age in nondisturbed adolescents. For the emotionally disturbed adolescents, the development of self-consciousness in temporary situations did not follow consistent patterns, as indicated by interaction effects. A significant negative relationship was found between intelligence test scores and self-consciousness in the disturbed group. The findings support the premise that social-cognitive shifts found in early to late adolescence are disrupted in disturbed populations. The mediating role of social experience as a factor in cognitive and emotional development is discussed. 相似文献

The relationship between family background, sexual behavior, and sex role typing was examined in 44 female and 47 male 15- to 17-year-old subjects at a New England preparatory school using verbal recall, self-report, and background information. Mother's profession was the best correlate of adolescent sexual behavior. The Spence Personal Attributes scale was correlated with sexual behavior in females and the Essay Recall measure was correlated with sexual behavior for males. Theoretical reasons for these relations are discussed. 相似文献

The purpose of this study was to examine differences in older adolescent and adult females' perceptions of age-appropriate behavior in adults. Subjects were three generations of maternally related females (95 older adolescents, 78 mothers, 83 grandmothers) who were administered a questionnaire designed to assess age-appropriate behaviors in three broad categories: recreation, occupation/career, and family. Major findings were that older adolescents were most tolerant of behaviors performed by individuals at varying ages while older women most closely ascribed to age constraints, and that the greatest agreement on appropriateness of age constraints concerned family relationships while least agreement concerned recreational activities. Results support the view that adolescents' values on family issues are consistent with those of their parents, and suggest that adherence to age norms increases throughout the life span or are the result of generational differences in socialization. 相似文献

Recent reports in the literature suggest that anxious individuals show an attentional bias to mood-congruent information. Various investigators have hypothesized that such anxiety-based coding biases contribute to the maintenance of mood disorders. The present study sought to determine if attentional biases in anxious subjects extends to the perception of neutral, as opposed to affect-laden, stimuli. A procedure used to determine the locus of attention to foveal and peripheral visual events was used in combination with two inter-stimulus intervals, fixed and variable, to examine anxious and non-anxious subjects' attentional biases. Mood states were established by a well-validated musical induction procedure. The results revealed an attentional bias to foveal visual events in non-anxious subjects and an attenuated or reversed (peripheral) bias in anxious subjects. The clinical implications of these findings are discussed. 相似文献

Research-structured vs clinically flexible versions of social learning-based marital therapy 总被引:1,自引:0,他引:1

The purpose of this study was to compare our structured research-based version of marital therapy from a social learning perspective with a clinically flexible version of the same treatment where treatment plans were individually-based and there was no specific number of treatment sessions. Thirty distressed married couples were randomly assigned to one of these two treatments. Assessment of outcome was based on global marital satisfaction, spouse reports of functioning in specific areas, and direct observational measures of communication. At posttest there were no differences in efficacy between structured and flexible treatments, although both treatments led to significant improvements. At a 6-month follow-up couples treated with the structured format were more likely to have deteriorated and flexibly treated couples were more likely to have maintained their treatment gains. 相似文献

We presented 7- to 9-month-old infants with repetitions of three- or four-tone sequences characterized by a particular rhythmic structure. We then evaluated their detection of changes in rhythmic structure in the context of randomly presented variations in tempo (rate) and frequency. Infants successfully differentiated between three-tones sequences with 1, 2 (X XX) and 2, 1 (XX X) structure as well as four-tone sequences with 2, 2 (XX XX) and 3, 1 (XXX X) structure. In other tasks, they indicated their ability to discriminate between contrasting tempos in the context of frequency variations. We conclude, then, that infants can categorize auditory sequences on the basis of rhythm and also on the basis of tempo. 相似文献
