Compared with mothers, fathers are dramatically underrepresented in clinical child and adolescent research. The author reviewed empirical and theoretical clinical child and adolescent literature to ascertain the reasons for this underrepresentation. Four somewhat interrelated factors are discussed: practical issues in participant recruitment, differential base rates of paternal vs. maternal psychopathology, theory-driven research based on sexist theories, and research assumptions based on outdated societal norms. Suggestions for future research are discussed, including parallel investigations of paternal characteristics whenever maternal characteristics are investigated, assessment of both similarities and differences in the role of fathers and mothers in child and adolescent psychopathology, and investigation of parenting factors for both fathers and mothers (e.g., time spent in actual caretaking, career vs. family orientation) in relation to child and adolescent psychopathology.  相似文献

The multiple and long-term effects of functional communication training relative to a common reductive procedure (time-out from positive reinforcement) were evaluated. Twelve children participated in a functional analysis of their challenging behaviors (Study 1), which implicated adult attention as a maintaining variable. The children were then matched for chronological age, mental age, and language age and assigned to two groups. One group received functional communication training as an intervention for their challenging behavior, and the second group received time-out as a contrast. Both interventions were initially successful (Study 2), but durable results were achieved only with the group that received functional communication training across different stimulus conditions (Study 3). Students whose challenging behaviors were previously reduced with time-out resumed these behaviors in the presence of naive teachers unaware of the children's intervention history. The value of teaching communicative responses to promote maintenance is discussed as it relates to the concept of functional equivalence.  相似文献

In this research we examined the relationships among cognitive styles using the categorization of Bion and styles of modulation of emotional behavior (hostile content) explored with the Gottschalk, et al. method applied to the speech of 20 female and 10 male undergraduate students whose ages ranged from 20 to 35 years. Their verbalization was produced in a standard stimulus situation of 3 minutes duration. Analysis indicated a relationship between hostile attitude and cognitive styles. In particular, those who were relatively less hostile presented higher frequencies of processes classified by Bion as D2, which are characterized by an attitude of expectancy and waiting, with a tendency to defend internal psychological themas.  相似文献

The extraction of three-dimensional shape from shading is one of the most perceptually compelling, yet poorly understood, aspects of visual perception. In this paper, we report several new experiments on the manner in which the perception of shape from shading interacts with other visual processes such as perceptual grouping, preattentive search ("pop-out"), and motion perception. Our specific findings are as follows: (1) The extraction of shape from shading information incorporates at least two "assumptions" or constraints--first, that there is a single light source illuminating the whole scene, and second, that the light is shining from "above" in relation to retinal coordinates. (2) Tokens defined by shading can serve as a basis for perceptual grouping and segregation. (3) Reaction time for detecting a single convex shape does not increase with the number of items in the display. This "pop-out" effect must be based on shading rather than on differences in luminance polarity, since neither left-right differences nor step changes in luminance resulted in pop-out. (4) When the subjects were experienced, there were no search asymmetries for convex as opposed to concave tokens, but when the subjects were naive, cavities were much easier to detect than convex shapes. (5) The extraction of shape from shading can also provide an input to motion perception. And finally, (6) the assumption of "overhead illumination" that leads to perceptual grouping depends primarily on retinal rather than on "phenomenal" or gravitational coordinates. Taken collectively, these findings imply that the extraction of shape from shading is an "early" visual process that occurs prior to perceptual grouping, motion perception, and vestibular (as well as "cognitive") correction for head tilt. Hence, there may be neural elements very early in visual processing that are specialized for the extraction of shape from shading.  相似文献

In keeping with Lakoff's (1975) notion that the use of women's language (WL) conveys uncertainty on the part of the speaker, the influence of communication apprehension, familiarity of partner, and topic on the use of selected WL forms was investigated. In dyadic conversation with a female friend or stranger, 71 female university students, who had completed the Personal Report of Communication Apprehension—Long, discussed a familiar or an unfamiliar topic. Multiple-regression analyses revealed that (1) communication apprehension was positively related to the use of question intonation, (2) familiarity of topic and partner were negatively related to the use of hedges, and (3) familiarity of topic was positively related to the use of intensifiers. There were no intercorrelations of the linguistic forms. These results challenge the notion that WL forms actually cohere to form a kind of language and suggest that the influence of social and psychological variables on the use of WL is much more complex and multifaceted than Lakoff believed.This article is based on portions of an Honour's thesis completed by the second author, and was presented at the Annual Convention of the Canadian Psychological Association held in Ottawa, Ontario, June 1990.  相似文献

It was reported by Jones (1990) that the design of British coins is systematically misremembered. Although the Queen's head in fact faces right, most people draw it facing left. It is possible, however, that the origin of this phenomenon does not reside in memory but instead in a leftward drawing bias. Two experiments of the three reported here tested this hypothesis. In Experiment 1, British participants attempted to recall the direction of the Queen's head but responded verbally instead of pictorially. The results were similar to those of Jones and thus contradict the hypothesis that misremembering of the Queen's head is caused by a leftward drawing bias. In Experiment 2, Canadian participants attempted to draw a Canadian coin. Leftward misremembering was not observed in this case. Thus the hypothesized importance of a leftward drawing bias was again not supported. Instead, the results provided support for the schema explanation of the Queen's Head memory illusion proposed by Jones. The results of Experiment 3, which compared memory for British coins and stamps, further bolstered this conclusion.  相似文献

We assessed the usefulness of the Western Aphasia Battery for distinguishing the language disturbances caused by Alzheimer dementia (AD) from those caused by stroke. Using discriminant function analyses, the multiple variable "aphasia quotient--reading quotient--writing quotient" classified 29 (72.5%) of the 40 patients correctly. These 29 patients included 8 of 10 patients with left hemisphere infarction and fluent aphasia; 6 of 10 with AD; 5 of 10 patients with right hemisphere infarction; and all 10 of the neurologically normal control subjects. The patients with AD and those with right hemisphere stroke were the most difficult to classify using the aphasia battery.  相似文献

Rats submitted to a chronic variable stress regime exhibited more inactivity during inescapable shock as compared with unstressed rats. Besides, chronic treatments with desipramine, imipramine, clomipramine, or phenelzine reduce the amount of inactivity exhibited during this aversive experience. Furthermore, the combination of both chronic treatments--stress and antidepressants--resulted in a potentiation of the antidepressant effect alone. This higher antidepressant efficacy may result from the interaction of the neural mechanisms triggered by chronic stress exposure and antidepressant drugs.  相似文献

The global threat of AIDS requires massive public educational campaigns that employ social and behavioral sciences such as psychology, sociology, and anthropology because sexual behavior possesses a social dimension. Research is concerned with what stimulates behavioral change, what are the prerequisites of learned behavior, and what enables personal control over the environment and future. Educational programs designing strategies for AIDS prevention require social and behavioral science content and input. Interdisciplinary provides general principles with psychological, social, and cultural aspects of human behavior. Without knowledge about psychological processes (thinking, perception, speech, aspects of personality, and interactive behavior) and social processes (economic conditions, social networks, and resources) which are implicated in health problems and also in AIDS, these educational programs cannot produce credible results. These programs and their subsequent implementation require their application in practice in a systemic and consistent fashion. Evaluations are also needed to make sure that the applied processes for behavioral change conform to methodological criteria that ensure their effectiveness. These types of studies are more complex than pure AIDS research which is aimed at finding a cure.  相似文献

This study examined the career and family role expectations and attitudes of women university students and both of their parents. Data collected from 292 families revealed that most daughters and their parents were traditional in their attitudes toward mothering, held somewhat egalitarian attitudes toward marital roles, and generally expected daughters to experience little frustration regarding future career and family roles. Differences and similarities among daughters, mothers, and fathers as well as between intact and dissolved families of various SES were examined. Implications of findings and suggestions for future research were discussed.This research was supported by grants from the University of Rhode Island Council on Research and from the College of Human Science and Services. Portions of this paper were presented at the National Council on Family Relations annual meeting, New Orleans, Lousiana, November, 1989 and at the Eastern Sociological Society annual meeting, Providence, Rhode Island, April, 1991. The authors thank Mary Ellen Reilly for her encouragement and assistance.  相似文献
