The Picture Exchange Communication System (PECS) is widely used with non-verbal children with autistic disorders as an Augmentative and Alternative Communication (AAC). Most of the participants in prior research on that method, although referred to as non-verbal, had initial vocal repertoires of at least a few words. The purpose of the present study was to examine whether 3 elementary-school-age children with autistic disorders whose vocal repertoires were severely limited, such as only a few phonemes, could acquire elementary communication skills using PECS. The present study incorporated task analysis, in which a sequence of picture-exchanging behaviors was divided into 4 components. The results demonstrated that all 3 children acquired the basic components of PECS within a short period. Data from the task analysis revealed that, with increased use of PECS, their prior mode of communication (grabbing, reaching, or crying) was gradually replaced, thereby indicating the reinforcing value embedded in PECS. In addition, the present data suggest that PECS training produced collateral behavioral changes, such as an emergence of intelligible vocalization, even in students who had previously had severely limited vocal repertoires.

The effectiveness of a behavioral skills training (BST) package to teach the implementation of the first three phases of the Picture Exchange Communication System (PECS) was evaluated with three adults who had no history teaching any functional communication system. A multiple baseline across participants design was used to evaluate the effectiveness of the training package, which consisted of a video, written and verbal instructions, modeling, rehearsal, and feedback. Results showed significant improvements relative to baseline in a short amount of training time, and that skills generalized to a learner with a severe developmental disability. Skills were maintained at one month follow-up for one participant.

A critical measure of intervention effectiveness is durability over time. Still, few studies have examined the long-term outcomes of support derived from a functional behavioral assessment as well as enablers and barriers that contribute to or impede successful outcomes. In the current study, a functional behavioral assessment was conducted with a 10-year-old boy with developmental disabilities who engaged in high-rate aggression. Based on the assessment results, a comprehensive support plan was developed and implemented, which resulted in a decrease in aggression and increase in activity engagement. His subsequent progress was followed for 3 consecutive school years. This longitudinal follow-up indicated that components of the plan remained effective; however, illness and implementation lapses resulted in decrements in progress.

We describe the behavior analytic approach to helping people with Asperger syndrome regarding social interaction and communication issues. In the behavior analytic approach, the cause of maladaptive behavior is not attributed to the disability itself. Maladaptive behaviors are viewed as a function of the interaction between an individual and the environment. Therefore, we assess these functional relationships and intervene by modifying aspects of the environment. Functional assessment is one of the most effective methods to evaluate the cause of problem behaviors and helps in the selection of an intervention strategy. We teach students functionally equivalent alternative behaviors that are socially appropriate and yet met the needs of the individual. Furthermore, we discuss the importance of teaching individuals with Asperger syndrome critical skills, including communication skills, self-management skills, and how to deal with anxiety.

Many children with autism require intensive instruction in the use of augmentative or alternative communication systems, such as the Picture Exchange Communication System (PECS). This study investigated the use of PECS with three young boys with autism to determine the impact of PECS training on use of pictures for requesting, use of intelligible words, and maladaptive behaviors. A multiple baseline-probe design with a staggered start was implemented. Results indicated that all of the participants quickly learned to make requests using pictures and that two used intelligible speech following PECS instruction; maladaptive behaviors were variable throughout baseline and intervention phases. Although all of the participants improved in at least one dependent variable, there remain questions regarding who is best suited for PECS and similar interventions.

Research in the area of behavior support has repeatedly demonstrated the positive effects of learning more effective and efficient communication on the challenging behaviors of individuals with developmental disabilities. More recently, augmentative and alternative communication strategies have been receiving increased attention as primary teaching goals for young children with autism. Use of picture exchange and choice-making opportunities has been reported to facilitate speech acquisition and/or result in increased communicative attempts across daily routines. The case study discussed in this article examines the effects of picture exchange on the severe aggressive behavior of a preschooler with autism who was at risk of losing his integrated school placement. Picture exchange was introduced within two play routines in the classroom. The effects of picture exchange on the student's aggression were evaluated within a multiple baseline design. Results indicated that the student's aggressive behavior was eliminated in a brief amount of time when picture exchanges were in place. These findings are discussed in terms of integrating augmentative communication into behavioral support planning and future research in this area. (http://www.proedinc.com)

The Picture Exchange Communication System (PECS) is widely used to teach children with language delays, including those with autism, functional language. A feature of PECS is that it incorporates principles deemed by some to be pivotal, leading to broader behaviour change. In this study, a 6-year-old child with autism was taught functional language using PECS. Along with measures of language gains, concomitant changes in nontargeted behaviours (play and TV viewing) following PECS training were observed. Results show increases in manding, initiations and cumulative word counts, as well as positive changes in the nontargeted behaviours.

Purpose: The aim of this study was to evaluate a program for implementing of the PECS in children with non-verbal ASD or with minimal verbalization in a school clinic belonging to the Unified Health System - SUS. Methods: This is a longitudinal study. The sample consisted of 22 children with nonverbal ASD or with minimal verbalization; 17 boys and 5 girls, aged 6 to 12 years old. The program consisted of 24 sessions of individual speech language therapy with the presence of the family member and followed the six phases originally proposed by the PECS Training Manual. Results: All children reached the first three phases. About 82% reached phase IV; 64% phase V and 19% phase VI. Family adherence was 96%. Conclusion: It was possible to test a PECS implementation program in 24 sessions and verify that children were able to achieve phases of discrimination and sentence construction, besides demonstrating gain in their lexical repertoire and reduction of non-adaptative behaviors.

Results: Participants who achieved high phases of PECS (≥PECS phase IIIb) differed significantly from those who mastered lower PECS phases (≤PECS phase IIIa) in terms of overall, verbal, and nonverbal mental age, matching abilities, and adaptive behavior level. Stimulus generalization was also associated with significant variation in PECS outcome. PECS outcomes could be predicted with good accuracy using a combination of these child characteristics and treatment variables. Conclusions: The findings from the current study suggest that children with relatively higher cognitive and adaptive skill levels are more likely to achieve higher phases of PECS; further, approaches to generalization training also play a role. Factors such as autism symptom severity and parental ratings of maladaptive behavior were not associated with significant differences in PECS outcomes. However, more research is needed. Implications: Gaining a better understanding of predictors of PECS outcomes is important to inform intervention, provide more accurate outcome expectations for families, and guide PECS teaching procedures. Although participants were more likely to achieve higher phases of PECS if they had a higher mental age, adaptive skill level, and matching skills, the average scores for these measures were well below those expected for same age peers. These results indicate that PECS is appropriate for use with children with clinically significant deficits in cognitive and/or adaptive abilities. Further, results suggest that even children who demonstrate more severe symptoms of autism and exhibit more challenging behavior can achieve higher phases of PECS.

The fact has been established by [20] one out of every 146 new-borns in UAE is affected with Autism Spectrum Disorder, and measuring the attention span using what method is difficult. It has been emphasized by [21] Children with ASD have a shorter attention span; hence the purpose of this study is to increase the attention span of autistic children in Abu Dhabi by using Picture Exchange Communication System (PECS). PECS is a picture-based communication method for people with little or no communication abilities to communicate using pictures [23].PECS is used in the classroom by teaching the children to make their requests by handing them an exchange card representing what they want. The goal of this study is to persuade parents and teachers of the use of PECS to improve the attention span of autistic students at the Abu Dhabi Autism Center. As a result, PECS is effective in increasing the attention span of autistic children, and parents and teachers are convinced that using PECS at Abu Dhabi Autism Center will help autistic children increase their attention span.

The aim of the study was to empirically assess the efficacy of Picture Exchange Communication System (PECS) in 5 children with autism spectrum disorder (ASD). This study was also intended to report parental feedback on using PECS with their children. Results: Current study shows that all the children were able to use PECS spontaneously and independently without any physical prompts. Children were able to generalize PECS at home with ease and were able to initiate communication on their own using the pictures. The mothers of the children reported that they observed a drastic subsidence in children's challenging behaviours and also improvement in their attention span. The findings from our study showed that PECS training is effective in improving the socio-communication skills in children with ASD who had restricted communication. On analysing the report, mothers stated that they were able to easily incorporate PECS at home with their child as it implements the use of actual pictures for communicative exchange. As PECS training paves the way for expression of the child's needs, there was also a significant reduction in the children's behavioural problems such as tantrums and other self-injurious behaviours. Conclusion: From this study, it can be concluded that PECS training is effective in improving various communicative temptations in socio-communication skills in children with ASD who have restricted communication. It was also noted that obtaining parental feedback periodically would help in generalization and it encourages the parents' involvement in the child's learning process.

Picture exchange communication system is an effective tool for improving communication skills in children with ASD in Malawi. Its adoption can facilitate learner independence, enhance classroom participation, and reduce frustration-related behaviors. Future research should explore long-term outcomes and strategies to scale PECS implementation across diverse Malawian settings
