Teaching Joint Attention to Children with Autism Through A Sibling‐Mediated Behavioral Intervention

Joint attention is pivotal to the development of complex social skills and language, and many individuals with Autism Spectrum Disorders display deficits in this domain. Behavioral interventions targeting joint attention are evidenced to be effective in teaching these skills to young children with autism, but these treatments have traditionally been implemented by adults in structured settings. Concerns regarding the generalizability of skills acquired under such conditions have been raised. Four typically developing children were trained to implement a joint attention intervention to their siblings with autism in the home. Joint attention was measured pre‐treatment and post‐treatment during play sessions and during a structured, adult‐mediated assessment to evaluate maintenance and generalization. Gains in responding to joint attention were observed for all four participants; gains in initiations were observed in three participants. Rates of imitation and behavioral requests also increased in structured and naturalistic settings. This study supports the efficacy of siblings as interventionists to target complex social skills in the natural environment. The implications of these findings for treatments targeting joint attention and for siblings as interventionists are discussed. Copyright © 2011 John Wiley & Sons, Ltd.     

The effect of behavioral skills training with general‐case training on staff chaining of child vocalizations within natural language paradigm

This study used behavioral skills training (BST) and general‐case training (GCT) in which the experimenter simulated child performance to teach three staff to conduct NLP and response chaining to increase three‐link vocal chains in three children with autism. Staff increased their correct NLP performance during post‐training in comparison to baseline. Two of three children emitted more vocal chains following training. This study demonstrated that BST and GCT were effective in training NLP and response chaining. When assessing social validity, both Board Certified Behavior Analysts (BCBAs) and teachers did not indicate an increase in staff members' teaching skills. Future research should develop effective technologies to chain vocal behavior and to teach staff and parents to implement response chaining. Copyright © 2009 John Wiley & Sons, Ltd.     

The effects of prompting,fading, and differential reinforcement on vocal mands in non‐verbal preschool children with autism spectrum disorders

There are few procedures to teach non‐vocal children vocal mands. This study evaluated the effects of prompting, fading, and differential reinforcement on eye contact, pointing, vocal approximations, independent requests and immature mands in three children with Autism Spectrum Disorders who in baseline emitted almost no independent vocal mands. This procedure resulted in a large and socially valid increase in independent vocal mands, other appropriate responses and near elimination of immature mands.

Evaluation of multiple‐alternative prompts during tact training

This study compared 2 methods of fading prompts while teaching tacts to 3 individuals who had been diagnosed with autism spectrum disorder (ASD). The 1st method involved use of an echoic prompt and prompt fading. The 2nd method involved providing multiple‐alternative answers and fading by increasing the difficulty of the discrimination. An adapted alternating‐treatments design showed that both procedures were more effective than a no‐intervention control condition. Providing multiple alternatives did not increase error rates or teaching time, and better maintenance was shown for tacts taught with the multiple‐alternative prompt.     

Noticing and commenting on what’s new: differences and similarities among 22‐month‐old typically developing children,children with Down syndrome and children with autism

Twenty 22‐month‐old typically developing children (TD), 11 children with Down syndrome (DS) and 10 children with autism (A), all functioning at a one‐ or two‐word linguistic level, were given eight series of four toys to explore. In each series, the first three toys (i.e. Trials 1–3) were identical, but the fourth toy (i.e. Trial 4) differed on a property or in identity. The children sat beside their mother and the experimenter while exploring the toys. Of interest was whether (1) the TD children would show more exploratory and communicative behavior related to the toys on Trials 1 and 4 than 2 and 3, and (2) how the response patterns of nontypically developing children would compare. The DS group showed a pattern of responding similar to that of the TD group with respect to their attention and interest in the toys, although a much lower rate of communicating with their mother. In contrast, the A group differed significantly from both other groups with respect to both the toys they found of interest and the timing of their topic initiations. Implications for observing declarative communication among children with Down syndrome and children with autism are discussed.     

An analysis of vocal stereotypy and therapist fading

A functional analysis for a boy with Down syndrome and autism suggested that vocal stereotypy was maintained by automatic reinforcement. The analysis also showed that instructions and noncontingent attention suppressed vocal stereotypy. A treatment package consisting of noncontingent attention, contingent demands, and response cost effectively reduced vocal stereotypy. The treatment package remained effective even when noncontingent attention was removed, making the procedure easier to implement. Also, the presence of the therapist in the room with the participant was faded systematically. After completion of fading, vocal stereotypy remained low during conditions similar to the no-consequence phase of the functional analysis.     

ADHERENCE TO DISCRETE‐TRIAL INSTRUCTION PROCEDURES BY RURAL PARENTS OF CHILDREN WITH AUTISM

Parents of children with autism spectrum disorders may not attempt treatment, even when effective treatment options are available. Little is known about how to improve frequency of attempts to implement treatment (‘treatment adherence’). We provided 32 rural parents of young children with autism spectrum disorders with either written or video training materials about how to implement discrete‐trial instruction and compared parental adherence between the written (control) and video (experimental) groups. Parents who received video instructions adhered to the training procedures to a significantly greater extent than did parents who received written instructions, suggesting that instruction format is a predictor of training success.

Maintaining social initiations of withdrawn handicapped and nonhandicapped preschoolers through a response-dependent fading tactic

The effects of a teacher-implemented intervention and fading package on the social initiations of three withdrawn preschool children were investigated. Subjects' social initiations and any peer responses were recorded sequentially during free play. Intervention involved teacher prompting and contingent praise of specific social initiations (sharing, assisting, verbally organizing play) by each subject toward an available peer. Results indicated that (a) teacher prompts and praise increased the frequency of subjects' target initiation, (b) target initiations typically received a positive peer response, (c) subjects' extended interactions with peers also increased, (d) abrupt, complete removal of teacher prompting resulted in similarly abrupt reductions in subjects' social initiations, whereas response-dependent fading maintained subjects' initiations and interactions above baseline levels. Follow-up data 2 1/2 months later showed that the social initiations and interactions of two of the children remained above baseline levels.This research was supported in part by Grant No. 007802088, U.S. Office of Special Education and Rehabilitation Services, and by Grant No. HD15051 from the National Institute of Child Health and Development.

Increasing social initiations in children with autism: effects of a tactile prompt

An ABAB design was used to assess the effects of a tactile prompting device (i.e., a vibrating pager) as a prompt for the social initiations of 3 children with autism during free-play activities with typically developing peers. Results indicated that the tactile prompt was effective in increasing verbal initiations for all 3 children, and responses to peers' initiations were higher for 2 participants when the tactile prompt was used. Efforts to reduce the frequency of prompts while still maintaining rates of initiations were partially successful for 1 participant.     

Self‐management of varied responding in three students with autism

One of the aspects of autism that is often held up as a hallmark of the disorder is a desire for sameness. Students with autism often show a marked lack of variability in language and play skills. The same behavioral patterns are repeated perseveratively, rather than attempting new patterns. In the current study, students diagnosed with autism were taught to self‐manage varied responding. Using a multiple baseline design, three children with autism were taught to self‐monitor and then to self‐manage in order to increase variability in play and social language. All three students demonstrated marked increases in variability during self‐management phases. These gains were maintained at one month follow‐up. Copyright © 2000 John Wiley & Sons, Ltd.     

EFFECTS OF NONCONTINGENT MUSIC ON VOCAL STEREOTYPY AND TOY MANIPULATION IN CHILDREN WITH AUTISM SPECTRUM DISORDERS

Noncontingent music has been shown to reduce engagement in vocal stereotypy in children with autism spectrum disorders, but its effects on appropriate collateral behavior remain unknown. Given that noncontingent music is typically implemented during periods of free play, clinicians may be concerned with the effects of the intervention on toy manipulation. Thus, we examined the immediate and subsequent effects of noncontingent music on engagement in vocal stereotypy and toy manipulation in four children with autism spectrum disorders by using a three‐component multiple schedule combined with a multi‐element design. The results suggest that noncontingent music (i) reduced immediate engagement in vocal stereotypy for three of four participants, (ii) never increased subsequent engagement in vocal stereotypy, and (iii) produced idiosyncratic effects on immediate and subsequent engagement in toy manipulation for two participants. The clinical implications of the results are discussed in terms of improving the treatment of vocal stereotypy using noncontingent music. Copyright © 2012 John Wiley & Sons, Ltd.
