Establishing initial auditory‐visual conditional discriminations and emergence of initial tacts in young children with autism spectrum disorder

Children with autism spectrum disorder (ASD) often display impaired listener skills, and few studies have evaluated procedures for establishing initial auditory‐visual conditional discrimination skills. We developed and evaluated a treatment package for training initial auditory‐visual conditional discriminations based on the extant research on training such discriminations in children with ASD with at least some preexisting skills in this area. The treatment package included (a) conditional‐only training, (b) prompting the participant to echo the sample stimulus as a differential observing response, (c) prompting correct selection responses using an identity‐match prompt, (d) using progressively delayed prompts, and (e) repeating trials until the participant emitted an independent correct response. Results indicated all participants mastered all listener targets, and the two participants for whom we tested the emergence of corresponding tacts showed mastery of most tacts without direct training. We discuss these results relative to prior research on listener skills and tacts.     

An evaluation of a visual–visual successive matching‐to‐sample procedure to establish equivalence classes in adults

Traditionally, behavior analysts have studied stimulus equivalence using a matching‐to‐sample (MTS) preparation. Although researchers have shown the utility of MTS to yield equivalence classes, the procedure requires several prerequisite skills for a learner to accurately respond. Previous research with humans and nonhumans has shown that relational responding can be produced via compound stimulus discrimination and successive matching‐to‐sample (S‐MTS). We conducted four experiments with college students to further evaluate the effectiveness of S‐MTS in the establishment of stimulus relations. S‐MTS trials consisted of the presentation of a single sample stimulus followed by one comparison in a fixed location on a computer screen. Depending upon the sample–comparison relation, participants touched (i.e., go) or did not touch (i.e., no‐go) the comparison stimulus. Following training of the baseline relations (AB/BC), we assessed the emergence of symmetry, transitivity, and equivalence performances (i.e., BA/CB and AC/CA). Results support the utility of the S‐MTS procedure as a possible alternative to traditional MTS. This study has direct implications for participants for whom traditional three‐array MTS procedures may be challenging.     

Go/no‐go procedure with compound stimuli with children with autism

The go/no‐go with compound stimuli is an alternative to matching‐to‐sample to produce conditional and emergent relations in adults. The aim of this study was to evaluate the effectiveness of this procedure with two children diagnosed with autism. We trained and tested participants to respond to conditional relations among arbitrary stimuli using the go/no‐go procedure. Both learned all the trained conditional relations without developing response bias or responding to no‐go trials. Participants demonstrated performance consistent with symmetry, but not equivalence.     

Effects of stimulus presentation order during auditory–visual conditional discrimination training for children with autism spectrum disorder

Children with autism spectrum disorder are typically taught conditional discriminations using a match‐to‐sample arrangement. Consideration should be given to the temporal order in which antecedent stimuli (the sample and comparison stimuli) are presented during match‐to‐sample trials, as various arrangements have been used in the extant literature. The purpose of the current study was to compare the effects of four stimulus presentation orders on the acquisition of auditory–visual conditional discriminations. The study included participants from a clinically relevant population (three children with autism spectrum disorder), employed clinically relevant teaching procedures, and included two presentation formats not included in previous comparison evaluations (simultaneous and sample‐first with re‐presentation conditions). Results were found to be learner‐specific; that is, a different stimulus presentation format was most efficient for each participant. We provide suggestions to evaluate stimulus control topographies and enhance experimental control in match‐to‐sample arrangements.     

Effects of response‐contingent stimulus pairing on vocalizations of nonverbal children with autism

Research on stimulus–stimulus pairing to induce novel vocalizations in nonverbal children has typically employed response‐independent pairing (RIP) procedures to condition speech sounds as reinforcers. The purpose of the present study was to evaluate the effects of a response‐contingent pairing (RCP) procedure on the vocalizations of three nonverbal boys diagnosed with autism spectrum disorder. During RCP, adult‐delivered sounds that were either paired with a preferred item (target sounds) or not (nontarget sounds) were presented contingent on a button‐press response. In Experiment 1, RCP was compared with an RIP procedure, in which the timing of sound presentations was yoked to the preceding RCP session. RCP produced a greater effect on all participants' target vocalizations than RIP. Experiment 2 demonstrated the effects of differential reinforcement of the vocalizations induced in Experiment 1. The results suggest that RCP may develop vocalizations more reliably than RIP procedures.     

Teacher–child interactions: relations with children's self‐concept in second grade

This study examined whether teacher–child interactions characterized by teacher involvement, structure, and autonomy support at the beginning of second grade predicted children's global, academic, social, and behavioural self‐concept at the end of second grade. The study was conducted in 30 second grade classrooms with 570 children and their teachers. Data included teacher reports of teacher–child interactions and child reports of self‐concept. Results showed that, when controlling for the initial level of self‐concept, children's social self‐concept was predicted by teacher involvement, structure, and autonomy support. In addition, teacher autonomy support predicted high academic self‐concept. Finally, these teacher–child interaction characteristics did not contribute to the behavioural and global self‐concept. The results were similar for boys and girls. Copyright © 2010 John Wiley & Sons, Ltd.     

The relationship between person–team fit with supervisor–subordinate guanxi and organizational justice in a Chinese state‐owned enterprise

The study examines how subordinates’ perceptions of justice in Chinese working teams are influenced by the person–team fit (or the misfit) of the supervisor–subordinate guanxi (SSG). We tested our hypotheses on a sample of 1,086 employees from 149 work groups in one state‐owned enterprise; using a combination of cross‐level polynomial regression and response surface analysis. The results showed that subordinates’ perceptions of justice, in terms of procedural, interactional, and distributive justice, were higher when individual SSG was congruent with the average SSG in the team (TSSG) at a high level than when an individual SSG was congruent with TSSG at a low level. Meanwhile, in the misfit situation, subordinates’ perceptions of the three dimensions of justice were higher when the individual SSG relative to TSSG (relative SSG, or RSSG) was surplus (individual SSG exceeded TSSG) versus RSSG deficient (TSSG exceeded individual SSG). Nevertheless, the subordinates’ perceptions of distributive justice were the highest when SSG and TSSG were almost equal in high level, as observed by integrating the fit with the misfit line. These findings highlight the important boundary cultural conditions of the psychological processes of justice and provide useful insights for international managers conducting their business in China.     

Emotional and self‐esteem consequences of perceiving discrimination against a new identity group

With a sample of Asian international students, the consequences of perceiving pervasive discrimination against one's in‐group were examined by experimentally manipulating perceived discrimination (pervasive vs rare) and group identification (low vs high). We report evidence that supports and integrates aspects of two contrasted models; namely, the discounting model and the rejection–identification model. Consistent with both models, the effects of perceiving discrimination on one's psychological well‐being depended on the level of group identification. Nevertheless, after reading about pervasive discrimination, low (vs high) identifiers reported less depressed affect, consistent with the discounting model. However, they also reported lower self‐esteem, consistent with the rejection–identification model.     

The Implementation of Mindfulness‐Based,Trauma‐Informed Parent Education in an Underserved Latino Community: The Emergence of a Community Workforce

In this practice‐oriented program review, a mindfulness‐based, trauma‐informed parent intervention, called Safe, Secure and Loved? (SSL), designed to strengthen nurturing parenting and children's resilience, was implemented in an underserved Latino community. Across 5 years, a volunteer community workforce of promotoras transformed an academic–community research partnership into a community‐led program partnership and established sustainable agency parent education programming. To better understand this transformation, we used a modified implementation science (IS) framework to structure interviews from members of the academic–community research partnership. Findings suggest that the commitment and cultural expertise of the volunteer community workforce acted as the major leadership drivers to create the community‐led program partnership. Employing mindfulness‐based, trauma‐informed parent education designed to promote nurturing parenting and children's resilience may be an effective training model to engage and mobilize a volunteer community workforce from an underserved community.     

Improving mother–child interaction in low‐income Turkish–Dutch families: A study of mechanisms mediating improvements resulting from participating in a home‐based preschool intervention program

This study examined whether the effects on cognitive and language outcomes of a recently developed home‐based educational intervention program, Opstap Opnieuw, for 4–6‐years‐old disadvantaged children could be explained by improved mother–child interaction. The present sample (n=30) was drawn from a larger sample of Turkish–Dutch families (n=181) for which in a previous study significant effects of Opstap Opnieuw were found on children's (first) language and cognitive pre‐math skill, 5 months after the program ended. The present study focused on two facets of interaction quality as possible mediators of these program effects: the mean cognitive distancing level of mothers' communication and instruction behaviour as an indicator of the cognitive and verbal stimulation provided, and the degree of cooperation as an indicator of mothers' social‐emotional support to their children. Both measures were based on systematic observation of mother–child interaction during sorting tasks. Participation in the program appeared to improve mothers' social‐emotional support behaviour substantially, but not their cognitive distancing behaviour. For Turkish (first language) vocabulary, about half of the program effect appeared to be mediated by the improved social‐emotional support. For cognitive pre‐mathematical skills, two‐thirds of the program effect appeared to be mediated by improved social‐emotional support. Mothers' cognitive distancing was moderately‐strongly related to children's vocabulary development, but did not mediate program effects. Some implications of the results are discussed.
