Clinical Archives of Communication Disorders Citeste mai mult...

Clinical Archives of Communication Disorders, 5, 31-41.Abstract: Purpose: We investigated the effects of behavioral skills training package with parents to use picture exchange communication system (PECS) with their children with autism spectrum disorder (ASD) to develop communication skills. Methods: Two parents and their children with ASD (one child per family) participated in this study. A multiple baseline design was used during the parents' training, and a changing criterion design was used during parents' implementation of PECS with children. Results: Results indicated that both parents implemented PECS intervention with their children with high procedural integrity and required minimal feedback through Bug-in-Ear at the end of the intervention. Moreover, both children acquired independent picture exchanges with their parents who implemented PECS training and generalized and maintained the skills. Conclusions: The findings suggest that when parents receive appropriate training and feed-back, they can train their children to use PECS to independently request desired items or activities. The current study extends existing research on PECS by teaching parents as the primary PECS trainers to implement the strategy with their children. 

Whitby, P., Kucharczyk, S. & Lorah, E. (2019). Teaching object exchange for communication to a young girl with autism spectrum disorder and visual impairment
Journal of Visual Impairment and Blindness Citeste mai mult...

Journal of Visual Impairment and Blindness, 113, 372-380.Abstract: AAC systems such as the Picture Exchange Communication System (Frost & Bondy, 2002) are found in evidence-based literature for learners with ASD. Adapting such systems for learners with comorbid conditions extends access of these practices to children and youths who could benefit and extends the research literature. Overall, object exchange was an effective intervention for Laura and her family.

Wendt, O., Hsu, N., Simon, K., Dienhart, A. & Cain, L. (2019). Effects of an iPad-based speech-generating device infused into instruction with the Picture Exchange Communication System for adolescents and adults with severe autism spectrum disorder
Citeste mai mult...

Behavior Modification, 43 (6), 898-932.Abstract: This study used a multiple baseline, single-subject research design to investigate the efficacy of an iPad®-based speech-generating device (SGD). The iPad was equipped with the SPEAKall!® application to function as a SGD. SGDs are a form of aided augmentative and alternative communication (AAC) allowing a user to communicate using digitized and/or synthesized speech. Instruction followed a modified version of the intervention phases from the Picture Exchange Communication System (PECS). This modified PECS protocol was implemented with two adolescents and one young adult between the ages of 14 and 23. All three participants were diagnosed with severe autism spectrum disorder and little to no functional speech. Dependent measures included the ability to request for edible and tangible items as the primary measure, and the ability to engage in natural speech production as an ancillary measure to determine simultaneous, additive effects on speech acquisition. Results indicated increases in requesting behaviors for all three participants across intervention and maintenance phases. Once participants mastered requesting of edible items, they were able to generalize the skill to tangible items. However, mixed results were found when targeting natural speech production. Based on the current findings, the infusion of an iPad-based SGD into PECS instruction may be effective in increasing initial requesting skills; however, a facilitative effect on increasing speech acquisition cannot necessarily be expected for every participant.

Alsayedhassan, B., Lee, J., Banda, D. Kim, K. & Griffin-Shirley, N. (2019): Practitioners' perceptions of the picture exchange communication system for children with autism
Journal of Disability and Rehabilitation Citeste mai mult...

Background: Autism spectrum disorder impacts social-communication. Picture Exchange Communication System is one of the methods to improve communication skills in individuals with autism. In spite of numerous studies on the effectiveness of Picture Exchange Communication System, no studies were conducted to examine the perceptions of practitioners who used the strategy.Method: An online survey was conducted with 120 practitioners (44 teachers and 76 therapists; 80.8% 20–49 years old; 80.8% graduate education) who used the Picture Exchange Communication System with children with autism. Using rating scales, practitioners reported their knowledge of Picture Exchange Communication System and their perceptions about importance, benefits, and barriers of utilizing Picture Exchange Communication System.Results: Practitioners reported they were confident when implementing Picture Exchange Communication System and considered integrating Picture Exchange Communication System at school to be important. Also, the practitioners indicated that Picture Exchange Communication System was easy to use and effective to develop communication skills in children with autism. However, they found that using Picture Exchange Communication System was time consuming.Conclusion: It is important to hear the viewpoints of practitioners concerning the use of Picture Exchange Communication System for individuals with autism spectrum disorder. This study found Picture Exchange Communication System is a useful strategy but has some barriers concerning its use. Future research is needed to confirm the current findings with a larger sample.

BMC Pediatrics Citeste mai mult...

Background: The use of technology to assist in the communication, socialization, language, and motor skills of children with Down's syndrome (DS) is required. The aim of this study was to analyse research findings regarding the different instruments of ‘augmentative and alternative communication' used in children with Down's syndrome. Methods: This is a systematic review of published articles available on PubMed, Web of Science, PsycInfo, and BVS using the following descriptors: assistive technology AND syndrome, assistive technology AND down syndrome, down syndrome AND augmentative and alternative communication. Studies published in English were selected if they met the following inclusion criteria: (1) study of children with a diagnosis of DS, and (2) assistive technology and/or augmentative and alternative communication analysis in this population. Results: A total of 1087 articles were identified. Thirteen articles met the inclusion criteria. The instruments most used by the studies were speech-generating devices (SGDs) and the Picture Exchange Communication System (PECS). Conclusion: Twelve instruments that provided significant aid to the process of communication and socialization of children with DS were identified. These instruments increase the interaction between individuals among this population and their peers, contributing to their quality of life and self-esteem.

Putri, C., Hastuti, W. & Adi, E. (2018). The influence the Picture Exchange Communication System method toward the communication ability of Autistic child,
Journal of ICSAR Citeste mai mult...

Children with autism have some very complex developmental disorders including communication, social interaction, emotions, and interest in certain behaviors. They need certain tools and methods for developing communication and language skills, especially in speaking skills. One of the methods is the Picture Exchange Communication System method. This research was conducted by using the Single Subject Research method with A-B-A design. Data collection was conducted in 20 sessions. The results of this study indicated that the effect of PECS method towards communication ability of children with autism. This was evidenced by an overlap percentage of 0%. The conclusion showed that PECS method has an effect towards the communication ability of autistic children.

Advances in Neurodevelopmental Disorders Citeste mai mult...

Given the limited evidence, along with a rapidly evolving state of technology, research is needed to drive effective and efficient communication intervention for people with severe to profound and multiple disabilities. The purpose of the current review was to synthesize and evaluate the state of the aided, augmentative and alternative communication (AAC) intervention literature for this population from 1997 to 2016. Results synthesized findings from 25 studies (n = 59) on the extracted participant characteristics, intervention, and dosage parameters from the studies. Results included an under-reporting of sufficient dosage parameters in addition to implications for future directions in the areas of maintenance, generalization, and discriminated use of skills, and bridging aided low and high-tech AAC interventions. 

Turan, M., Moroz, L. & Paquet-Croteau, N. (2012). Comparing the effectiveness of error-correction strategies in discrete trial training
Behavior Modification Citeste mai mult...

Error-correction strategies are essential considerations for behavior analysts implementing discrete trial training with children with autism. The research literature, however, is still lacking in the number of studies that compare and evaluate error-correction procedures. The purpose of this study was to compare two error-correction strategies: Independent Probe and Delay across learners with autism in an intensive intervention program. Two studies were conducted. The first study compared the two procedures across receptive tasks for 3 individuals, and differential effects were seen across learners. The second study compared the two procedures across tact trials with two of the same learners and found that individual differences were noted, but in addition, the more effective error-correction strategy was consistent across the two verbal operants (i.e., receptive in Study 1, tacts in Study 2). These combined studies suggest the effectiveness of error-correction strategies may beindividualized to the learner but may generalize across operants
