自我和物体为参照系的心理旋转分离：内旋效应

采用虚拟的旋转不同角度左、右手模型,构建“左右手判断(Left and right hand judgment: LR)”任务和“相同－不同判断(same and different judgment: SD)”任务,考察这两种实验任务是否都存在内旋效应和角度效应,以此推论被试采用何种旋转策略。结果发现：（1） 两种实验任务结果均表现出显著的角度效应。（2）在LR任务条件下,存在显著的内旋效应,而在SD任务中不存在内旋效应。从而表明当人手图片作为心理旋转材料时,它具有双重角色。被试心理旋转加工时究竟选用何种参照系的旋转策略,与实验材料和实验任务两者都密不可分

European starlings are capable of discriminating subtle size asymmetries in paired stimuli

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.     

Transformation of avoidance response functions in accordance with same and opposite relational frames

Research on the emergence of human avoidance behavior in the absence of direct contact with an aversive event is somewhat limited. Consistent with work on derived relational responding, the present study sought to investigate the transformation of avoidance response functions in accordance with the relational frames of Same and Opposite. Participants were first exposed to nonarbitrary and arbitrary relational training and testing in order to establish Same and Opposite relations among arbitrary stimuli. The training tasks were; Same-A1-B1, Same-A1-C1, Opposite-A1-B2, Opposite-A1-C2. Next, all possible combinatorially entailed (i.e., B-C and C-B) relations were tested. During the avoidance-conditioning phase, one stimulus (B1) from the relational network signaled a simple avoidance response that cancelled a scheduled presentation of an aversive image and sound. All but one of the participants who met the criteria for conditioned avoidance also demonstrated derived avoidance by emitting the avoidance response in the presence of C1 and the nonavoidance response in the presence of C2. Control participants who were not exposed to relational training and testing did not show derived avoidance. Implications of the findings for understanding clinically significant avoidance behavior are discussed.     

Extensions and Mechanisms of Mindfulness‐based Cognitive Therapy: A Review of the Evidence

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.     

Effects of Adlerian Play Therapy on Reducing Students' Disruptive Behaviors

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.     

A Protective Factors Model for Alcohol Abuse and Suicide Prevention Among Alaska Native Youth

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.     

肺癌治疗中辨证论治与循证医学的矛盾与统一

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。     

Theoretical frameworks for working with harder to reach families: lines,curlicues, and spirals: comment on Donovan and Pocock

This article comments on the Donovan and Pocock articles appearing in this issue, both of which address the evolution of theory and practice in family therapy. An emphasis is placed on the importance of integration and a shared philosophy of theory and practice in our current political and economic managed care climate, in which it is critically important to embrace the integrated and chaotic whole of what is happening in theory and in practice.
