Facilitating the emergence of convergent intraverbals in children with autism

Convergent intraverbals represent a specific type of intraverbal in which multiple components of one speaker's verbal behavior control a specific verbal response from another speaker (e.g., Speaker 1: What wooly, horned animal lives in the high country? Speaker 2: Bighorn sheep). To foster the development of advanced language, Sundberg and Sundberg (2011) proposed prerequisite skills that may engender the emergence of novel, convergent intraverbals. We used a multiple‐probe design with both nonconcurrent (across participants) and concurrent (across stimulus sets) components to evaluate the effects of training these prerequisite skills on the emergence of convergent intraverbals with four children with autism. Participants showed the emergence of convergent intraverbals at mastery levels after they displayed mastery performance on all of the prerequisite skills identified by Sundberg and Sundberg, lending support to their characterization as prerequisites. We discuss these findings in terms of operant mechanisms that may facilitate the development of generative language.     

Teaching pronouns to individuals with autism

It is well documented that individuals with autism often have significant difficulty with learning to use pronouns appropriately. It does not appear, however, that published studies have systematically investigated teaching procedures for these skills. This study evaluated the effectiveness of a teaching procedure to increase correct pronoun usage as a listener and speaker across four different pronoun pairs (i.e., mine/yours, I/you, me/you, and my/your) using a multiple‐probe design (across pronoun pairs). One participant with autism was taught to discriminate between mine/yours, I/you, me/you, and my/your as both a listener and a speaker. Generalization of the participant's behavior was obtained across novel instructors, places, and stimuli.     

PEAK关系训练系统：孤独症语言障碍康复的新方法

PEAK (Promoting the Emergence of Advanced Knowledge, 促进高阶知识涌现)关系训练系统是全球首个同时整合了斯金纳的《言语行为》和后斯金纳主义的“关系框架理论”, 促进孤独症谱系障碍(Autism spectrum disorders, ASD)患者的语言、学习、社交等核心技能发展的语言行为评估训练系统。截至2018年底, PEAK关系训练系统由以下4个模块组成：直接训练模块、泛化模块、等价关系模块、功能转化模块。每一模块依据难易程度分别设置了184个目标能力的评估方法及训练课程。已发表的多项实证研究表明, PEAK关系训练系统打破了《语言行为里程碑评估及安置程序》(Verbal Behavior Milestones and Placement Program, VB-MAPP) 对ASD患者进行里程碑评估时出现的“天花板效应”, 有望比VB-MAPP提供更全面、高阶的语言行为评估体系。此外, PEAK关系训练系统表现出的评估工具的信效度良好、多项效果研究显著、实践中易操作等特性, 使其不仅适用于专业人员教学, 未来在ASD患者家庭干预模式中也有潜在的应用价值。     

语言标识对情绪体验的影响

本研究通过两个实验考察了语言标识对个体情绪体验的调节作用。实验一探讨了中性标识对不同类型的情绪体验的影响,结果发现与韩文字符标识相比,中性双字词标识时被试对负性图片的消极情绪体验强度显著降低。实验二进一步探讨了不同情绪色彩的词语的标识效应,结果发现与中性标识相比,负性或正性标识时被试对负性图片的消极情绪体验程度更低。结果表明了语言标识对负性情绪体验具有显著的调节作用,并且标识效应的产生依赖于词汇语义信息的通达。     

没听到？“听”到！——来自听觉表象神经机制研究的证据

近年来听觉表象开始得到关注,相关研究包括言语声音、音乐声音、环境声音的听觉表象三类。本文梳理了认知神经科学领域对上述三种听觉表象所激活的脑区研究,比较了听觉表象和听觉对应脑区的异同,并展望了听觉表象未来的研究方向。     

Intercontinental telehealth coaching of therapists to improve verbalizations by children with autism

This study examined the effects of intercontinental telehealth coaching on the mastery of therapists’ skills and improvements in verbalizations by children with autism, testing whether telehealth can be a solution for underserved communities in developing countries such as Georgia‐Sakartvelo in Eastern Europe. Three therapists delivering and three children with autism receiving early‐intervention services from the nongovernmental organization Children of Georgia in Tbilisi participated. Experimenters provided coaching from Virginia, USA to therapists in Georgia‐Sakartvelo. Observers in Georgia‐Sakartvelo and in Virginia conducted the behavioral observations. We used inexpensive communications technology to provide the coaching and a multiple‐baseline design across participants to evaluate the effects of the intervention. Therapists demonstrated improvements in two classes of behaviors: correct command sequences and positive consequences. The children demonstrated improvements with echoics and mands. The study demonstrated that telehealth can be a good model for delivering early‐intervention services to children with autism in underserved and distant regions of the world.     

Establishing derived categorical responding in children with disabilities using the PEAK‐E curriculum

The purpose of the study was to evaluate a procedure to generate derived categorical responding by three children with disabilities and to promote the emergence of untrained intraverbal categorical responses. In the study, three 4‐member equivalence classes including three stimuli (A, B, and C) and a category name (D) for each class were trained using a match‐to‐sample procedure. Test probes were conducted for categorical responding, including both a trained (D‐A) and two derived (D‐B, D‐C) relational responses, as well as the emergence of untrained intraverbal categorical responding (D‐A/B/C) throughout the study. Relational training was effective at promoting the emergence of categorical responding, and two of the three participants demonstrated the emergence of additional intraverbal responding without prior training. The results provide further evidence supporting the practical utility of stimulus equivalence as well as the PEAK‐E curriculum.     

Transfers of stimulus function during roulette wagering

Twenty‐five recreational gamblers were initially asked to place bets on either red or black positions on a roulette board in a simulated casino setting. Each participant was then exposed to a stimulus pairing observing procedure which attempted to develop equivalence classes between one color (black or red) and traditionally positive words (e.g., love, happy, sex) and another color (black or red) and traditionally negative words (e.g., death, cancer, taxes), in the absence of consequence manipulations. Twenty‐one of the twenty‐five participants demonstrated greater response allocation to the color position on the roulette board that participated in a relational network with the positive words. Variations in sequencing of experimental conditions had no impact on poststimulus‐pairing wagers, but did impact tests for equivalence accuracy.     

Training intraverbal bidirectional naming to establish generalized equivalence class performances

The purpose of this study was to evaluate the effects of tact and intraverbal training on the establishment of generalized equivalence classes. Seventeen college students were exposed to tact training, listener testing, and intraverbal training (A'B’ and B'C’) in two experiments. Visual–visual matching‐to‐sample and intraverbal tests measured performances consistent with the formation of equivalence classes. Generalization was assessed with four novel sets of stimuli. In the second experiment, matching‐to‐sample tests for baseline relations (AB, BC) were eliminated to control for the possibility that equivalence classes were developed through exposure to these visual stimulus–stimulus relations. Thirteen of 17 participants passed all matching‐to‐sample and intraverbal posttests. Results suggest that when trained and emergent intraverbal relations were not maintained or were faulty, participants did not respond correctly during matching‐to‐sample posttests.     

What Are the Effects of a Parent-Implemented Verbal Responsive Intervention on Preschoolers With Externalizing Behavior Problems?

This research was conducted to assess the impact of a parent-based verbal responsive intervention, aiming to enhance parents’ responsiveness and communication strategies, by way of a sample of parents and their preschool-aged children with a clinical level of externalizing behavior problems. Twenty-one parents received the intervention, consisting of eight 1.5-hour sessions. The study tested the hypothesis that the intervention led to an improvement in parenting variables and a decrease in children’s behavior problems, assessed by a multimethod procedure. The results partially confirmed the prediction, as they showed an enhancement of parents’ responsiveness and parent self-efficacy belief, which are promising findings, but no modifications of negative practices. These effects persisted for 4 months after the intervention. Moreover, a decrease in children’s externalizing behavior problems was reported by parents in a questionnaire, but this was not confirmed by an observational paradigm. This last result seems to show that a parent-implemented verbal responsive intervention is necessary for some children with externalizing behavior difficulties but often insufficient, and has to be part of a multidisciplinary treatment approach.
