This study examined the outcomes of a competing activities intervention to decrease skin picking exhibited by a 9-year-old student with comorbid diagnoses. Results of an ABCBAB design revealed that the use of student-selected manipulatives resulted in reduced skin picking. 相似文献

Data from the National Election Studies were examined in an effort to isolate cognitive dissonance of two kinds: dissonance arising from a behavioral commitment in the form of voting, and dissonance arising from inconsistencies associated with having supported the losing candidate. Feeling thermometer ratings of the two principal presidential candidates obtained before and immediately after six elections (1972, 1980, 1984, 1988, 1992, and 1996) were analyzed. Regression estimates supported a dissonance reduction explanation of observed attitude changes. Voters, as compared to nonvoters, tended to increase the evaluative distance between candidates after an election, whereas supporters of the losing candidate were more likely than supporters of the winning candidate to decrease such evaluative distances. An additional examination of voters yielded results consistent with dissonance theory: After the election, respondents reporting favorable evaluations of both candidates (a difficult choice) tended to spread comparative candidate evaluations compared to respondents who were favorable toward only one candidate (an easy choice). The results both support and cast doubt on prior studies. 相似文献

Small deviations from bilateral symmetry (fluctuating asymmetries) are cues to fitness differences in some animals. Therefore, researchers have considered whether animals use these small asymmetries as visual cues to determine appropriate behavioral responses (e.g., mate preferences). However, there have been few systematic studies of animals' abilities to visually discriminate such minor asymmetries. If the asymmetries cannot be discriminated, fluctuating asymmetry can not be a visual cue. Here, we report an investigation of European starlings' (Sturnus vulgaris) abilities to discriminate small size asymmetries. We trained starlings, through operant conditioning in a free-flight aviary, to discriminate achromatic, symmetric paired stimuli from size-matched asymmetric stimuli. By starting the learning process with a large asymmetry and progressing through sequential trials of decreasing asymmetry, we elucidated a behavioral limit to asymmetry discrimination. We found that starlings are capable of discriminating a 10% size asymmetry. There was weaker evidence for discrimination of 5% asymmetry but no evidence for signal discrimination at 2.5% size asymmetry. This level of asymmetry discrimination suggests that many size asymmetry cues in nature can be discriminated by birds. At each level of asymmetry discrimination, we also tested whether starlings could generalize their learned symmetry preference to unreinforced novel images. Consistent with previous findings, we found that starlings could generalize their symmetry preferences. 相似文献

Mindfulness‐based cognitive therapy (MBCT) was originally developed to prevent depressive relapse and recurrence and has also been widely extended to new patient populations and target problems over the last 14 years. We provide a comprehensive review of this literature, examining the strength of the evidence base for specific populations and target problems and identifying questions for future research to address. Specifically, we review studies addressing the use of MBCT for depressive disorders (prevention of depressive relapse and treatment of residual and current depressive symptoms), the use of MBCT in the treatment or management of other mental disorders (bipolar disorder, anxiety disorders, mixed anxiety and depression symptoms, disordered eating, personality disorders, and psychosis), and the use of MBCT in behavioural medicine contexts. Additionally, we discuss the extension of MBCT during specific developmental periods, like childhood, pregnancy and post‐partum, and adult caregiving, and, finally, we address the use of MBCT among clinical health‐care providers. In the second section, we review hypothesised mechanisms of change in MBCT and reflect on implications for theories of how MBCT works in the application to various patient populations and target problems. We also consider research addressing active ingredients and what is known about the “dosage” of meditation practice. We conclude with a summary of recommendations for future research. 相似文献

This randomized controlled study examined the effectiveness of Adlerian play therapy (AdPT) with 58 elementary school students (48% Latino, 33% European American, 19% African American) exhibiting disruptive classroom behaviors. Teachers and raters blinded to treatment group assignment reported that children in the experimental group demonstrated a statistically significant reduction in behavior problems and that AdPT demonstrated moderate to large treatment effects. Teachers also reported a statistically significant reduction in stress in their relationships with students receiving AdPT. 相似文献

This study provides an empirical test of a culturally grounded theoretical model for prevention of alcohol abuse and suicide risk with Alaska Native youth, using a promising set of culturally appropriate measures for the study of the process of change and outcome. This model is derived from qualitative work that generated an heuristic model of protective factors from alcohol (Allen et al. in J Prev Interv Commun 32:41–59, 2006; Mohatt et al. in Am J Commun Psychol 33:263–273, 2004a; Harm Reduct 1, 2004b). Participants included 413 rural Alaska Native youth ages 12–18 who assisted in testing a predictive model of Reasons for Life and Reflective Processes about alcohol abuse consequences as co-occurring outcomes. Specific individual, family, peer, and community level protective factor variables predicted these outcomes. Results suggest prominent roles for these predictor variables as intermediate prevention strategy target variables in a theoretical model for a multilevel intervention. The model guides understanding of underlying change processes in an intervention to increase the ultimate outcome variables of Reasons for Life and Reflective Processes regarding the consequences of alcohol abuse. 相似文献

肺癌的个体化治疗是依托于循证医学和飞速发展的分子生物学技术开启的西医治疗的新篇章,但同时也面临着很多困境。而中医辨证论治思想在朴素哲学思想的启领下,早已体现了个体化治疗的灵魂。笔者融合辨证论治思想,现代循证医学证据,提出了肺癌中西医治疗新的概念,从个体差异的绝对性出发,论述了辨证思想与循证医学共存的必然性及两者之间的矛盾。循证医学的结论可通过对大量个体化辨证治疗的研究而不断更新,从而更好地指导辨证治疗,这是未来中西医临床肺癌诊疗的必经之路。 相似文献
