The behavioral research on teaching individuals who have profound multiple handicaps is reviewed. The primary focus is on determining the degree to which behavioral research has demonstrated the teaching of meaningful skills to this population. Results of the review indicate that investigations have demonstrated, albeit inconsistently, that behavior change has resulted from contingency management interventions with persons who have profound multiple handicaps. However, there is little evidence that such interventions have resulted in meaningful behavior change according to currently accepted criteria for beneficially affecting the quality of life of persons with serious handicaps. Potential explanations for the lack of such evidence are offered, including the relative lack of research attention given to this issue, the possible ineffectiveness of the components of the technology applied, and possible ineffective application of the potentially effective technology. Suggestions for future research are discussed in terms of developing more effective educational and habilitative services for persons with profound multiple handicaps. In particular, we suggest research on a wider variety of behavioral teaching procedures, providing more comprehensive evaluations of the applications of procedures and developing treatment programs that do not focus solely on traditional skill acquisition.  相似文献

Using several measures of sexual activity, 24 male and 30 female Sprague-Dawley rats were subjected to a pretreatment test and 3 posttests (immediate and Recovery Days 4 and 7) following REM sleep deprivation in a water tank. With careful controls, sexual activity was not significantly affected by the sleep treatments. Data do not support motivational hypotheses.  相似文献

A number of recent theoretical and empirical articles have examined various aspects of volunteerism. Research which has established the increasing importance of career development as a primary goal of many volunteers has largely been concerned with individuals already established in their careers. This article extends current research by focusing on recent or soon-to-be college graduates. It integrates career-development volunteerism research with recent work from the job search literature. The paper includes specific suggestions for obtaining volunteer experience which targets employer-identified desirable job skills.  相似文献

A cental thesis of Paul Gray's work is that a "developmental lag" pervades modern psychoanalysis in its failure to assimilate and apply knowledge gained about the role of the unconscious ego in intrapsychic life. But Gray himself, it is proposed, has become a victim of a new "developmental lag," of his own construction. As he somewhat single-mindedly pursued the ramifications of his "developmental lag" concept, Gray may have foreclosed on some noteworthy ideas developing around him. The most important example is his claim--herein refuted--that proper interpretive technique can avoid being infused with transference. He also seems to have rejected the theoretical importance of the internalization of the analyst and the clinical usefulness of countertransference. While emphasizing defense analysis, he ignores defenses such as splitting, denial, and disavowal as substantive problems for his technique of close-process attention. Gray's "undoing" of the rapprochement between "ego analysis" and "id analysis" by viewing the matter as an either-or proposition undermines the very real value of his contribution to the field.  相似文献

Current neuropsychological models propose that some age-related cognitive changes are due to frontal-lobe deterioration. However, these models have not considered the possible subdivision of the frontal lobes into the dorsolateral and ventromedial regions. This study assessed the age effects on 3 tasks of executive function and working memory, tasks dependent on dorsolateral prefrontal dysfunction; and 3 tasks of emotion and social decision making, tasks dependent on ventromedial prefrontal dysfunction. Age-related differences in performance were found on all tasks dependent on dorsolateral prefrontal dysfunction. In contrast, age-related differences were not found on the majority of the tasks dependent on ventromedial prefrontal dysfunction. The results support a specific dorsolateral prefrontal theory of cognitive changes with age, rather than a global decline in frontal-lobe function.  相似文献

Hypotheses derived from defensive attribution theory and social identity theory were tested in 3 laboratory experiments examining the effects of plaintiff and observer gender on perceived threat, plaintiff identification, and sex discrimination. In Study 1, women differentiated plaintiffs on the basis of gender, whereas men did not. Study 2 showed that this bias occurred because employment discrimination was personally threatening to women but not to men. In Study 3, the bias was reversed in a child custody context. As predicted, men found this context to be significantly more threatening than did women and subsequently exhibited a similarity bias. Mediation analyses suggested that responsibility attributions explained most of the variance in discrimination judgments associated with the plaintiff gender by observer gender interactions.  相似文献

This study investigated the nature of anomia and semantic memory deficits in patients with Alzheimer's disease (DAT). We measured reaction time (RT) and the N400 event-related brain potential (ERP) in a word-picture semantic priming paradigm for DAT patients and elderly controls. For patients, pictures were classified as a function of the individual's naming ability to determine whether naming deficits reflected a failure to access a picture's name or reflected a deterioration of its semantic representation. As expected, DAT patients had significantly poorer naming performance than controls. For successfully named pictures, robust RT and ERP priming effects were obtained in both groups. In DAT patients, priming for unnamed pictures was heterogeneous. The results are discussed in terms of current hypotheses of semantic memory deficits in DAT.  相似文献

Research on effective pharmacotherapy for body dysmorphic disorder (BDD) has rapidly increased in recent years, with emerging data consistently indicating that serotonin reuptake inhibitors (SRIs) are often efficacious for this disorder. Although data are limited, it appears that higher SRI doses and longer treatment trials than those used for many other psychiatric disorders are often needed to treat BDD effectively. Approaches to treatment-resistant BDD have received little investigation, but available data indicate that switching to another SRI and several SRI-augmentation strategies may be helpful. This article reviews the empirical literature on BDD and offers a recommended approach to the pharmacotherapy of this distressing and often disabling disorder.  相似文献

This article reports on a sample of 147 women under age 35 living in rural areas in China who had attempted suicide and were treated in the emergency room of hospitals in four different locations. The interview instrument took 2 to 3 hours to complete and included audiotaped in-depth interviews with the patient and family members (separately); detailed evaluation of the circumstances surrounding the attempt, life events, and the family environment; and a formal psychiatric evaluation by an attending-level psychiatrist. Overwhelmingly, the method used by the attempters was poisoning with highly lethal pesticides and organic fertilizers. The women's suicidal behavior was characterized by high levels of impulsivity; little effort to seclude themselves before and after ingesting poison; and low rates of mental illness, including depression. Detailed suggestions are made about ways to implement suicide prevention strategies within the particular social and economic context of China.  相似文献

We consider the problem of axiomatizing various natural successor logics for 2-dimensional integral spacetime. We provide axiomatizations in monomodal and multimodal languages, and prove completeness theorems. We also establish that the irreflexive successor logic in the standard modal language (i.e. the language containing and ) is not finitely axiomatizable.  相似文献
