The present meta-analysis examined the effects of psychosocial treatments at reducing deleterious outcomes of sexual abuse. The meta-analysis included a total of 35 published and unpublished studies written in English, focusing on youth under the age of 18, and evaluating the effectiveness of treatments for the most common negative outcomes of sexual abuse: PTSD symptoms, externalizing problems, and internalizing problems. Results revealed medium effect sizes for PTSD symptoms, externalizing problems, and internalizing problems following treatment for sexual abuse. This study also examined the potential moderating effects of treatment (e.g., modality, duration, inclusion of caregiver) and participant (e.g., age, gender, ethnicity) characteristics. Results indicated that longer interventions were associated with greater treatment gains while group and individual treatments were equally effective. These findings shed new light on treatment effectiveness and provide useful information regarding the conditions under which treatment may be most effective. Future directions for research in this area are discussed. 相似文献

Conscious visual perception can fail in many circumstances. However, little is known about the causes and processes leading to failures of visual awareness. In this study, we introduce a new signal detection measure termed subjective discriminability of invisibility (SDI) that allows one to distinguish between subjective blindness due to reduction of sensory signals or to lack of attentional access to sensory signals. The SDI is computed based upon subjective confidence in reporting the absence of a target (i.e., miss and correct rejection trials). Using this new measure, we found that target misses were subjectively indistinguishable from physical absence when contrast reduction, backward masking and flash suppression were used, whereas confidence was appropriately modulated when dual task, attentional blink and spatial uncertainty methods were employed. These results show that failure of visual perception can be identified as either a result of perceptual or attentional blindness depending on the circumstances under which visual awareness was impaired. 相似文献

Guided by the American Psychological Association's principles of evidence-based practice, this article reviews a single-case treatment outcome study whereby a client characteristic, sexual identity, was integrated into the assessment and treatment of social anxiety symptoms. The case involved a young adult European-American male who presented to a training clinic with a primary diagnosis of social anxiety disorder as well as secondary symptoms of excessive worry and concerns of sexual identity confusion. Recent evidence suggests that gay men report more symptoms of social anxiety when compared to heterosexual men, and those who make more efforts to conceal their sexual identity experience increased anxiety and have greater difficulty committing to a personal identity. Further, it has been hypothesized that fear of rejection from heterosexual individuals underlies this anxiety. The client attended 50 sessions over the course of 18 months. Treatment progress was assessed via self-report questionnaires assessing social anxiety and worry. Consistent with principles of evidence-based practice, a cognitive behavioral treatment protocol was employed at the outset of therapy and resulted in a decline in the client's social anxiety scores. However, once the case conceptualization and treatment focus shifted to focus on sexual identity, his scores continued to decline at an even steeper rate. He ultimately came to identify himself as having a same-sex sexual orientation, began living his life in a manner consistent with that identification, and reported a number of positive outcomes at termination of therapy. Implications for treatment of social anxiety in sexual minorities are discussed. 相似文献

Confirmatory factor analysis was used to test the invariance of an oppositional defiant disorder toward adults, attention-deficit/hyperactivity disorder-hyperactivity/impulsivity, attention-deficit/hyperactivity disorder-inattention, and an Academic Competence factor model between mothers' and fathers' ratings within Brazilian (n = 894), Thai (n = 2,075), and American (n = 817) children with the Child and Adolescent Disruptive Behavior Inventory (G. L. Burns, T. Taylor, & J. Rusby, 2001a, 2001b). The results showed invariance of item loadings, intercepts, and residuals, as well as factor variances, covariances, and means between mothers' and fathers' ratings within each sample. Convergent and discriminant validity was also observed for the between-parent factor correlations, thus providing additional support for the construct validity of the Child and Adolescent Disruptive Behavior Inventory. The confirmatory factor analysis invariance procedure provides a much better way to examine between-source ratings of behavior problems in children than do the simple correlation and raw discrepancy score procedures. 相似文献

ABSTRACT— The problem of mapping differing sensory stimuli onto a common category is fundamental to human cognition. Listeners perceive stable phonetic categories despite many sources of acoustic variability. What are the neural mechanisms that underlie this perceptual stability? In this functional magnetic resonance imaging study, a short-interval habituation paradigm was used to investigate neural sensitivity to acoustic changes within and between phonetic categories. A region in the left inferior frontal sulcus showed a pattern of activation consistent with phonetic invariance: insensitivity to acoustic changes within a phonetic category and sensitivity to changes between phonetic categories. Left superior temporal regions, in contrast, showed graded sensitivity to both within- and between-category changes. These results suggest that perceptual insensitivity to changes within a phonetic category may arise from decision-related mechanisms in the left prefrontal cortex and add to a growing body of literature suggesting that the inferior prefrontal cortex plays a domain-general role in computing category representations. 相似文献

The question why synaesthesia, an atypical binding within or between modalities, occurs is both enduring and important. Two explanations have been provided: (1) a congenital explanation: we are all born as synaesthetes but most of us subsequently lose the experience due to brain development; (2) a learning explanation: synaesthesia is related to some learning process during childhood. Three recent studies provide conflicting support for these explanations. Two studies supported the idea that synaesthesia is learned by showing that the frequency of everyday language implicitly modulates the synaesthetic experience. Another study argued that synaesthesia reflects basic, innate magnitude representations. In this paper we reassess these points of view, and show that it is possible for both to be valid. These findings are integrated into an interactive specialization account of development in order to explain the neuronal mechanism underlying synaesthesia. 相似文献

We assessed the efficacy of time delay and peer modeling procedures in increasing autistic children's spontaneous verbalizations of affection. Four autistic children were taught to spontaneously say “I like (love) you” in response to a hug from a familiar person and their mother. Generalization from a free play training setting to free play outdoors and at home was assessed. Ancillary social and affection behaviors were also observed. Results indicated that the time delay was a quick and effective procedure for all the children. Peer modeling was unsuccessful in teaching the target behavior. 相似文献

In 1977, DiGiuseppe and Miller provided a review of the literature assessing the effectiveness of Rational-Emotive Therapy (RET). In 1984, McGovern and Silverman completed a similar review for outcome studies conducted from 1977 through mid-1981. This present study is meant as a continuation of those reviews. The 89 studies reviewed are divided into three sections: outcome studies that do not compare Rational-Emotive Therapy with other types of treatment; a review of outcome studies that do compare RET with other types of psychotherapy; and a review of Rational-Emotive outcome studies that either combine RET with other therapies or are not appropriate for the first two sections. There does appear to be some increased sophistication in the research conducted since 1982. Increases were noted in the number of control groups used in the current research as well as in the number of follow-up studies. There also appears to be an improvement in the comparison of RET with other forms of therapy, and the number of problem areas in which RET has been tested has increased. A decrease in post-test only studies and an increased variety of subjects have also improved the current research. Issues such as socioeconomic status and I.Q. of subjects, duration of treatment, and lack of longitudinal studies remain unaddressed. It is suggested that future researchers concentrate on these specific problems to improve the credibility of RET. This review coincides with the previous findings that RET is a valuable, effective therapy that warrants increased research to broaden its application.Manuel S.
