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.     

白细胞介素-6和胎盘生长因子对子痫前期影响的研究

为探讨影响子痫前期患者发病的因素,对照性检测了子痫前期患者羊水中白细胞介素-6和胎盘中胎盘生长因子的变化。结果显示：子痫前期患者白细胞介素-6和胎盘生长因子均明显下降,且二者下降水平呈高度正相关。故联合检测白细胞介素-6和胎盘生长因子将对评估子痫前期的病情及指导临床决策具有重要意义。     

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.     

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.     

Functional analytic psychotherapy and the treatment of obsessive compulsive disorder

This paper argues that Functional Analytic Psychotherapy (FAP) can contribute to the treatment of Obsessive Compulsive Disorder (OCD). FAP is a behavior analytically informed approach to talk-therapy, developed by Kohlenberg and Tsai. It uses natural occurrences of clinically relevant behavior in the client-therapist relationship to promote therapeutic change. A selection of vignettes of client-therapist dialogues involving two clients with OCD is discussed. The examples show how natural interactions between therapist and client can be used to bring therapeutic technique closer to the natural occurrences of obsessive-compulsive behavior. Furthermore, the fragments illustrate that FAP can encompass exposure and response prevention. Therefore, the in vivo learning during the session as promoted in FAP can be an asset in the treatment of clients with OCD, and it deserves attention in future treatment research.     

The effects of signaling stimulus presentation during noncontingent reinforcement

The effects of signaling the return of items or attention during treatment with noncontingent reinforcement were examined. First, functional analyses showed that the problem behavior exhibited by 2 teenagers with developmental disabilities was sensitive to social positive reinforcement. Next, delivery of the stimulus that maintained problem behavior on a fixed-time (FT) schedule was compared to a condition in which the removal of the stimulus during the same FT schedule was immediately preceded by a statement indicating that the stimulus would be returned and the initiation of a digital timer. Results show that the FT schedule reduced problem behavior, and the addition of an informative statement and a timer further decreased problem behavior.
