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.     

Social interaction and cognitive growth: An examination through the role‐taking skills of deaf and hearing children

Recent research using theory‐of‐mind tasks has rekindled interest in the possibility that social interaction makes a significant contribution to cognitive development. It is proposed here that this contribution may be most pronounced with phenomena that, like belief or affective states, are internal and abstract. A more modest contribution is envisaged with phenomena that are overt and perceptible. The proposal is explored via comparison of deaf and hearing children's ability to engage in affective and perceptual role‐taking, since the aspects of social interaction that have been implicated in cognitive development are known to be problematic for deaf children. Therefore, the proposal of more marked consequences for internal and abstract phenomena leads to the hypothesis that deaf children should lag behind hearing children on affective role‐taking, while showing little or no difference on perceptual role‐taking. The hypothesis was tested in two studies, one involving 10 deaf children and 10 hearing children aged 6.94– 8.93 years and the other involving 25 deaf children and 20 hearing children aged 5.08– 11.58 years. In both studies, affective role‐taking was examined using a task developed from Chandler (1973), while perceptual role‐taking was examined via an extension of Hughes and Donaldson's (1979) hiding task. The results provide consistent support for the hypothesis, and patterns of correlation between age, affective performance and perceptual performance give clues to the relevant developmental mechanisms.     

Patterns of language and discourse comprehension skills in school‐aged children with autism spectrum disorders

Åsberg, J. (2010). Patterns of language and discourse comprehension skills in school‐aged children with autism spectrum disorders. Scandinavian Journal of Psychology 51, 534–539. The present study examined patterns of language and discourse comprehension skills in Swedish school‐aged children with autism spectrum disorders (ASD) (n = 16) as compared to a slightly younger group of typically developing children (n = 16) matched for non‐verbal cognitive ability. Results suggested significantly lower abilities in narrative discourse comprehension for the ASD group, but not in oral receptive vocabulary or reception of grammar. This difficulty with discourse‐level comprehension appeared to be of a general nature, as no evidence was found for the hypothesis that participants with ASD would find comprehension of inferential discourse information disproportionally more difficult than stated information, or for the hypothesis that discourse processing in ASD would be characterized by an elevated processing of explicitly stated narrative details. The study has clinical and educational implications, as the findings suggest that children with ASD would benefit from being offered specific support for discourse‐level comprehension.     

Social interaction skills and theory of mind in young children

Two studies explored relations between peer social skills and theory of mind in young children. In Study 1, a global teacher rating of social skills with peers, performance on a traditional false-belief task, a standardized assessment of auditory language comprehension, and a time sampling of amount of speech with peers were obtained. Positive, but moderate, zero-order correlations were observed between the false-belief measure and social skills, and false belief accounted for a significant amount of additional variance in social skills after covarying age and the 2 measures of language. Study 2 replicated the findings of Study 1 by using a larger sample and a standardized teacher questionnaire. The results are discussed with regard to the critical role of a mentalistic theory of behavior for human social interactions.     

Equivalence‐based instruction of academic skills: Application to adolescents with autism

This study evaluated the efficacy of three equivalence‐based instruction procedures on the acquisition of novel academic skills by 3 adolescents diagnosed with autism in a school setting. The skills targeted for instruction were related to topics in history, science, and mathematics, and were taught using different training structures from the PEAK‐E curriculum. All participants demonstrated mastery of the trained relations and the tested derived relations following all variants of equivalence‐based instruction.     

Training and testing music skills in a boy with autism using a matching‐to‐sample format

A 16‐year old boy with autism was taught music skills using a matching to sample procedure. He was trained and subsequently tested for the formation of four 4‐member classes, including different visual music stimuli, and Norwegian and Vietnamese labels for different major and minor chords. Four different stimuli sets were trained both in one‐to‐many (OTM) and many‐to‐one (MTO) training structures. Further, we explored if the reaction times to comparison stimuli increased from training to testing. Results showed that the participant formed equivalence classes with music relations. Furthermore, there were small differences only between OTM and MTO with respect to stimulus equivalence responding. The reaction times to comparison stimuli increased from training to testing, and were most pronounced for the equivalence trials. Copyright © 2010 John Wiley & Sons, Ltd.     

Comparing the teaching interaction procedure to social stories for people with autism

This study compared social stories and the teaching interaction procedure to teach social skills to 6 children and adolescents with an autism spectrum disorder. Researchers taught 18 social skills with social stories and 18 social skills with the teaching interaction procedure within a parallel treatment design. The teaching interaction procedure resulted in mastery of all 18 skills across the 6 participants. Social stories, in the same amount of teaching sessions, resulted in mastery of 4 of the 18 social skills across the 6 participants. Participants also displayed more generalization of social skills taught with the teaching interaction procedure to known adults and peers.     

Imitative interaction increases social interest and elicited imitation in non‐verbal children with autism

Recent studies indicate that being intensely imitated for a brief period of time increases social interest among children with autism. The aim of this study was to replicate and extend these findings. Twenty children with an autism spectrum disorder (ASD) were randomly assigned to one of two interaction strategies: imitation (n=10) or contingent (n=10). The children had little or no functional speech, and their developmental age averaged 25 months (mean chronological age =6:5 years). Both conditions were presented with repeated sessions of a modified version of Nadel's ‘still‐face’ paradigm (still‐face/intervention/still‐face/spontaneous play). The analysis revealed a significant increase of both proximal and distal social behaviours (touch and look at person) for the imitation condition, which confirms previous reports. In addition, an increase in elicited imitation, as measured with the PEP‐R developmental assessment procedure, was also observed for children in the imitation condition, but not in the contingent condition. This finding extends earlier reports in that it suggests that the social expectancies unlocked by imitation also spread to tasks outside the experimental setting.

A rapid assessment of skills in young children with autism

Educational interventions based on the principles of behavior analysis are highly effective for establishing skills in young children with autism. As a first step in program development, the child's current skill level is determined by evaluating performance on tasks drawn from a preestablished curriculum. However, few specific guidelines have been delineated for conducting these skills assessments or interpreting the results. In this study, we evaluated an efficient methodology for conducting skills assessments. Six children who had been diagnosed with autism participated. The relative efficacy of two assessment packages--one containing several reinforcement procedures and one containing several potentially effective prompts--was evaluated across two to three skills for each child using multiple baseline and reversal designs. Results suggested that the methodology was useful for matching targeted skills to appropriate interventions.
