图形型归纳推理的神经机制:一项fMRI研究

利用fMRI脑成像技术探讨图形型归纳推理的神经机制。设计了一种由图形形状和条纹方向描述的简单几何图形组成的归纳推理任务,这种图形型任务与以往研究中常用的语句型归纳推理任务是同质的。根据两个图形共享特征数量的不同设计了两种实验任务:共享两个特征(2T)和共享一个特征(1T),以休息基线(Rest)作为控制任务。2T和1T任务均为归纳推理任务,但2T任务包含知觉特征整合成分,而1T任务不包括。结果发现:与控制任务相比,归纳推理任务在前额区(BA6、9、11、46、47)、尾状核、壳核和丘脑等脑区有显著激活,反映了"前额皮层-纹状体-丘脑"通路在图形型归纳推理中的重要作用;图形型归纳推理中的知觉信息整合与右侧额下回(BA47)、双侧尾状核头部、壳核等脑区有关。     

基于神经生理学的疼痛测量

疼痛是一种受多重因素影响的复杂主观感受。临床上,疼痛测量主要依赖于患者的主观评价。然而,这种传统的疼痛测量方法具有多方面的局限。近年来,研究者借助生理记录、脑电和功能磁共振等技术,揭示疼痛的神经生理、心理机制,挖掘与疼痛相关的神经生理指标,进而构建有效、客观和精确的疼痛评价体系。在基础研究和临床实践中,这些技术有望弥补传统疼痛测量方法的不足,从而极大推动疼痛测量及其治疗等相关领域研究的发展。     

Functional analyses and treatment of precursor behavior

Functional analysis has been demonstrated to be an effective method to identify environmental variables that maintain problem behavior. However, there are cases when conducting functional analyses of severe problem behavior may be contraindicated. The current study applied functional analysis procedures to a class of behavior that preceded severe problem behavior (precursor behavior) and evaluated treatments based on the outcomes of the functional analyses of precursor behavior. Responding for all participants was differentiated during the functional analyses, and individualized treatments eliminated precursor behavior. These results suggest that functional analysis of precursor behavior may offer an alternative, indirect method to assess the operant function of severe problem behavior.     

Speech Perception: Cognitive Foundations and Cortical Implementation

ABSTRACT— Speech perception includes, minimally, the set of computations that transform continuously varying acoustic signals into linguistic representations that can be used for subsequent processing. The auditory and motor subroutines of this complex perceptual process are executed in a network of brain areas organized in ventral and dorsal parallel pathways, performing sound-to-meaning and sound-to-motor mappings, respectively. Research on speech using neurobiological techniques argues against narrow motor or auditory theories. To account for the range of cognitive and neural attributes, integrative computational models seem promising.     

Culture-sensitive functional analytic psychotherapy

Functional analytic psychotherapy (FAP) is defined as behavior-analytically conceptualized talk therapy. In contrast to the technique-oriented educational format of cognitive behavior therapy and the use of structural mediational models, FAP depends on the functional analysis of the moment-to-moment stream of interactions between client and therapist. This distinctive feature makes FAP particularly sensitive to the challenges posed by cultural differences between client and therapist. Core elements of FAP philosophy are invoked to argue that this vulnerability paradoxically implies an increased ability to capture and use relevant issues in the therapy process with culturally different clients. This argument focuses FAP's preference for concrete behavior over theoretical modeling, its emphasis on functional principles rather than topographically defined techniques, and its inclusion of the therapist's behavior in the assessment of clients' clinically relevant behavior. Suggestions are given concerning how academic and practical training and personal experience may be used to foster sound multicultural practice.     

Beijing Calling... Mobile Communication in Contemporary China

Subsequently, with the recent wave of industrialization, China has become the “factory” of the globalized world. The modernization of this country, however, is not confined to the provision of production at a low added value: It also entails technological appropriation and innovation. In particular, China represents the biggest world market for mobile phones and will soon dominate the Internet market. In this country, the total number of mobile and fixed-line subscribers exceeds 750 million, and the total number of Internet users is more than 162 million. The present study focuses on how, after a decade of mobile phone use, the inhabitants of Beijing evaluate the changes in the social and communicative sphere as a result of the introduction of the mobile phone. In this paper, we present some results of a quantitative research, specifically focused on mobile communication. Based on face-to-face questionnaires administered to a convenient sample of 487 respondents, this study addresses the following research questions: After a decade of mobile phone use, how do Chinese people perceive the importance of this device? To what extent do the adoption and use of mobile phones increase or decrease social connectivity in contemporary China? To what extent does the use of mobile phones in everyday life enhance or reduce the communications – do they make you feel closer to or more distant from other people? What are the variables that predict users’ attitudes toward mobile phones in China?     

慢性腹痛

慢性腹痛病史较长,性质不定。引起慢性腹痛的原因很多,除器质性疾病外,一些功能性疾病也引起,如最终找不出具体原因,则可称之为功能性腹痛综合征。诊断比较困难,也容易误诊,甚至误治,外科医生应特别慎重。误诊的思维原因包括对引起慢性腹痛的原因认识不全面,思维惰性,辩证思维不周密和思维简化等。     

A comparative effectiveness trial of functional behavioral assessment methods

Clinicians report primarily using functional behavioral assessment (FBA) methods that do not include functional analyses. However, studies examining the correspondence between functional analyses and other types of FBAs have produced inconsistent results. In addition, although functional analyses are considered the gold standard, their contribution toward successful treatment compared with other FBA methods remains unclear. This comparative effectiveness study, conducted with 57 young children with autism spectrum disorder, evaluated the results of FBAs that did (n = 26) and did not (n = 31) include a functional analysis. Results of FBAs with and without functional analyses showed modest correspondence. All participants who completed functional communication training achieved successful outcomes regardless of the type of FBA conducted.     

Some comments on the distinction between intention and intentionality

The topic of intention has recently received attention from behavior analysts (Hineline, 2003; Neuman, 2004). From a behavior-analytic perspective, it is important to identify the circumstances in which people utter such terms, and to identify the potential circumstances that maintain such utterances. It follows that from a behavior-analytic perspective, the focus is primarily on those who observe behavior and attribute intentions to that behavior. However, there has not been a distinction between intention and intentionality. The current analysis stresses the distinction between the two terms, both from a traditional point of view (psychologist and layperson) and from a behavior-analytic point of view. From a behavior analyst's perspective, the distinction is important because observers may be responding to distinct functional relations when they attribute intention or intentionality to behavior.
