We investigated the effects of background anger, provocation, and methylphenidate on emotional, physiological, and behavioral responding in children with attentiondeficit hyperactivity disorder (ADHD) with and without concurrent aggression. Our study revealed that ADHD boys showed more emotional and physiological distress when exposed to an interaction in which an administrator chastised each boy's favorite counselor, compared to a friendly interaction between the two adults. The background anger manipulation did not affect the aggressive behavior of the boys against an opponent in an aggressive game. High-aggressive (HA) ADHD boys were more likely to respond to provocation with aggression than low-aggressive (LA) ADHD boys, but only LA boys showed increased physiological reactivity with increasing provocation. Methylphenidate resulted in increased heart rates under all conditions and did not interact with any of the other findings.This project was conducted while the first author had the support of National Institute of Alcohol Abuse and Alcoholism grant AA 06267.The authors wish to thank the staff members of the 1987 Summer Day Treatment Program who assisted in conducting this project. The authors also express their appreciation to Karen Guthrie for coordinating the medication assessment and to Hart Blanton for computer programming.  相似文献

Early lexical development in children with focal brain injury   总被引:4,自引:0,他引:4  
Early lexical development in 27 children with focal brain injury was studied cross-sectionally and longitudinally. Data were obtained from children between 12 and 35 months of age who acquired their lesion prenatally or within the first 6 months of life. Results for the group as a whole provide clear evidence for delays in lexical comprehension and production, and for a larger number of comprehension/production dissociations than would be expected by chance. In addition, a significant number of children were observed having unusual difficulty mastering predication and/or using an atypically high proportion of closed class words (suggesting reliance on holistic/formulaic speech). Analyses by lesion type revealed no effect of lesion size. Analyses according to side of lesion revealed that children with right-hemisphere damage produced a higher proportion of closed class words, suggesting heavy reliance on well-practiced but under-analyzed speech formulae. Children with left-hemisphere damage were slightly better in comprehension than children with right-hemisphere damage. In addition, left posterior lesions were associated with greater delays in expressive language, and delays were more protracted in children with left posterior damage. No differential effects of left posterior damage were found for lexical comprehension.  相似文献

Conclusion Both Schutz and Gurwitsch describe reality as having a manifold character: Schutz speaks of multiple realities and Gurwitsch of orders of existence. Both hold that one realm of reality has a privileged status compared to the others: common everyday experience. However, in spite of this apparent convergence in their views, a closer reading of their various works reveal the important difference in what they understand under common everyday experience.For Schutz, it is the world of social action, characterized by him as paramount reality because of the constitutive processes of the experiences of time, space, sociality and meaning involved in action. For Gurwitsch, the realm of common everyday experience represents the counterpart and the origin of the constructed realm of science: therein lies its status of paramount reality. But what it really refers to is not ordinary experience, as most of his statements suggest, but pre-predicative experience, wherefrom the categories of the natural sciences, namely space and time, originate. Gurwitsch speaks of this pre-predicative experience, which he also calls primordial experience, as being essentially perceptual experience. However, he limits perceptual experience to sensory perception, leaving out the symbolic, social and action-related components of perception and becomes thus inconsistent with his adherence to the dismissal of the constancy hypothesis in his field theory of consciousness. The dismissal of the constancy hypothesis implies the recognition of the appresentational structures involving symbols, action and Others as inherent components of every perception. Schutz disagrees with Gurwitsch's reduction of the life-world Erlebnisse to sensory perception and this issue becomes the core of their debate on the phenomenon of paramount reality.  相似文献

This study investigates the incidence and nature of sexual coercion among sorority women. Particular emphasis is placed on sexual coercion that occurs within the context of fraternal life. Overall, almost half of those studied had experienced some form of sexual coercion, 24% experienced attempted rape, and 17% were victims of completed rape. Almost half of the rapes occurred in a fraternity house, and over half occurred either during a fraternity function or was perpetrated by a fraternity member. This study provides evidence that fraternities represent a social context that tolerates, if not actually encourages, sexual coercion of women, including sorority women.  相似文献

The authors present a comprehensive four-step process for conducting initial career assessment by interview. The process assesses skills, interests, values, non-work relationships, goals and activities, and psychological aspects such as self-esteem and work attitudes. The interview process is flexible, internally consistent and portable. Step One analyzes the client's work history and includes reasons why such a history may be inadequate. Step Two examines work-related preferences. Step Three investigates lifestyle context, and Step Four produces a summary of all the accumulated interview information, including options the client wishes to avoid. Detailed worksheets accompany the article.This article has been adapted, with permission, from Chapter 3, Promoting Client Self Understanding, in Yost, E. B., and Corbishley, M. A.Career Counseling: A Psychological Approach. San Francisco: Jossey-Bass, 1987.  相似文献

Based on the recruitment experience in a family therapy research project with heroin addicts, this paper explores the difficulties of researcher networking with other social service agencies. Concepts from contextual family therapy are used to explore four general areas that contribute to successful intra-agency relationships: 1) Evaluating the nature of larger system relationships; 2) identifying the resources and needs of a clinic; 3) joining with the counseling staff; and 4) addressing the impact of public policy and ideology on clinic life. A case of engaging one clinic is presented and nine guidelines for engaging large community settings for participation in family therapy research are offered. These areas are considered in light of the relational dynamics that arise when working with multiple social service systems.An earlier version of this paper was presented at the American Family Therapy Association conference in Washington, DC, June 1986. The authors are grateful to the recruitment staff of the Intergenerational Family Therapy Project: Guillermo Lopez, Bart Rubin, Sharara Godfry, and Armando Chenyek. This research was supported in part by a grant to Guillermo Bernal from the National Institute on Drug Abuse (DA03543).  相似文献

Functionalism and type-type identity theories   总被引:1,自引:0,他引:1  
Conclusion Token-token identity theorists do not and need not deny that it may frequently be the same (kind of) brain state which on different occasions fills the functional rôle definitive of a given mental state. That is not at issue. What is at issue is whether functionally-oriented identity theorists should make two claims or three claims.The two claims they customarily make are, first, that each instance of a mental state is an instance of a brain state, and, secondly, that being in a mental state is having in one a state filling the relevant functional rôle. But to be in a mental state is to have that state in one. To be in pain is to have pain, to desire water is to have desire for water, and so on; just as to be poisoned is to have poison in you. (It is to have what is poison for you at the time, of course; and likewise for pain, desire and so on.)Our paper has been about a third sort of claim — relating particularly not to being in a mental state, nor to instances of that state, but to the mental state itself. We have argued that functionally-oriented identity theorists can and should make, in addition to the first two claims, the third type-type identity claim that mental states are brain states. Consequently a token brain state is a token of pain in a derivative sense. What makes it a token of pain is that it is a token of the type of brain state which realizes the pain-rôle for the organism at the time.  相似文献

Mental shock can produce retrograde amnesia   总被引:1,自引:0,他引:1  
Subjects in three experiments saw a short film of a mentally shocking event in which a young boy is violently shot in the face. Compared to other subjects who saw a nonviolent version of the same film, those who saw the mentally shocking version showed poorer retention of the details of the film. Retention was poorer whether measured by recognition or recall. Furthermore, impaired memory occurred only when the event was mentally upsetting, and not when it was merely unexpected but not upsetting. These results suggest that mentally shocking episodes may disrupt the lingering processing necessary for full storage of information in memory.  相似文献
