The purpose of this study was to investigate the effects of an augmentative and alternative communication (AAC) app with transition to literacy (T2L) software features (i.e., dynamic text and speech output upon selection of a graphic symbol within the grid display) on the acquisition of 12 personally relevant single words for individuals with severe autism spectrum disorder (ASD) who had minimal or no speech. The study implemented a single-subject, multiple-probe, across word sets design with four participants. All four participants in this study demonstrated increased accuracy reading targeted single words and results from this study provide preliminary evidence that the T2L features can positively affect the single-word learning of individuals with ASD who have minimal speech and limited literacy skills.

Current literature suggests a lack of empirically validated strategies for teaching reading skills to children who use augmentative and alternative communication (AAC). The current study implemented a single-subject, multiple-probe-across-subjects design to investigate the effects of direct instruction in single-word reading on the performance of students who use AAC. The instructional program targeted the reading skills of 5 participants who had severe speech impairments and ranged in age from 9 to 14 years old. All 5 participants reached criterion for matching targeted written words to corresponding pictures. Three of the 5 participants demonstrated generalization of reading skills to novel-word reading, and 4 of the 5 generalized reading skills to book contexts. Implications and directions for future research are discussed.

Purpose The purpose of this study was to investigate the effect of the Transition to Literacy (T2L) feature within video visual scene displays (VSDs) on the single-word reading of academic vocabulary concepts (i.e., weather concepts) by a preliterate adolescent with cerebral palsy and minimal speech. Method A single-subject, multiple-probe, across-word-sets design was used to evaluate the effects of the intervention. The intervention used an augmentative and alternative communication app programmed with video VSDs embedded with hot spots with the T2L feature to teach the adolescent 12 academic vocabulary words. Results The adolescent acquired all target words successfully with only minimal exposure to the written words through the app and was able to generalize her learning to two novel tasks. Using Tau-U to evaluate the size of the observed effects, there were very large effects across all word sets. Conclusions The findings from this study demonstrate the effectiveness of the T2L feature to improve single-word reading in preliterate individuals with minimal speech. The use of video VSDs and T2L technology together may offer professionals a unique way to complement current augmentative and alternative communication devices and literacy instruction for adolescents with minimal speech who are preliterate.

Purpose Technology features that maximize communicative benefit while minimizing learning demands must be identified and prioritized to amplify the efficiency and effectiveness of augmentative and alternative communication (AAC) intervention. Picture symbols with paired text are a common representation feature in AAC systems for children with autism spectrum disorder (ASD) who are preliterate, yet little research about their comparative benefit exists. Method Four school-age children with ASD and limited speech who were preliterate participated in two single-subject studies. In one study, communication of high imageability words (e.g., nouns) on an AAC app during a book-reading activity was compared across two representation conditions: picture symbols with paired text and text only. In the second study, communication of low imageability words (e.g., verbs) was compared. Both studies had baseline, intervention, generalization, and maintenance phases. Results Prior to intervention, participants communicated across both representation conditions at low rates except two participants who were relatively successful using picture symbol with paired text representations of high imageability words. In response to intervention, all participants demonstrated increases in communication across representation conditions and maintained the increases. Participants demonstrated generalization in the text-only representation condition. Conclusions Children with ASD who were preliterate acquired communication at comparable rates regardless of whether an AAC app utilized picture symbol with paired text or text-only representation. Therefore, while larger scale research is needed, clinicians and technology developers could consider increasing the use of text in AAC representation given the inherent value associated with learning to recognize written words.

Purpose The purpose of this study was to determine the effects of augmentative and alternative communication (AAC) intervention using a speech-generating device (SGD) on acquisition, maintenance, and generalization of multistep requesting and generic small talk in three children with severe autism spectrum disorder (ASD) between the ages of 7 and 13 years. Method A multiple-baseline design across participants combined with a posttreatment multiple-generalization-probe design was used to assess acquisition, generalization, and maintenance of target communicative behaviors with the experimenter and the participants' familiar communication partners (FCPs). Intervention was composed of systematic instruction in the use of an SGD using least-to-most prompting, constant time delay, error correction, and reinforcement. Results Visual analysis established a strong functional relationship between the independent variable and the two dependent variables (i.e., requesting preferred activities, engaging in generic small talk) for all three participants. Effect size indicator analyses corroborated these findings, indicating strong effects for performing multistep requesting and medium effects for engaging in generic small talk. All participants were able to generalize the acquired communicative behaviors to request new and untrained snacks and activities and engage in generic small talk with FCPs who were not part of the training. Maintenance of acquired communicative behaviors was demonstrated 3 weeks post completion of intervention. Conclusion This study provides preliminary evidence that AAC intervention using an SGD and incorporating least-to-most prompting, constant time delay, error correction, and reinforcement is effective in terms of multistep requesting and generic small talk behaviors in children with severe ASD.

Purpose In this study, we investigated the efficacy of a least-to-most (LTM) prompting procedure (Ault & Griffen, 2013; MacDuff, Krantz, & McClannahan, 2001; Neitzel & Wolery, 2009) for increasing use of multisymbol messages in school-age children with autism spectrum disorder (ASD) who use augmentative and alternative communication (AAC) during a storybook reading activity. Method In the study, we used a single-subject, multiple-probe research design across participants (Kazdin, 1982) with 6 children (ages 8–12) with ASD and who used AAC systems for communication. There were 4 phases in this investigation: (a) baseline, (b) intervention, (c) generalization, and (d) maintenance. Results All participants exhibited a positive increase in multisymbol message production almost immediately upon introduction of the LTM prompting procedure. Conclusions The results of the investigation contribute important information on the efficacy of the LTM prompting procedure for teaching use of multisymbol messages to school-age children with ASD who use AAC.

This study aims to improve the ability of dynamics musical skills of autistic student using Augmentative and alternative communication (AAC) media. Augmentative and alternative communication (AAC) interventions have been shown to improve both communication and learning skills in children and youth with autism spectrum disorders and other developmental disabilities. There are many strategies educators use to aid a child to communicate. Visual aides have been used successfully in helping children with autism communicate. A picture system called AAC Media allows teachers to make pictures to help students on the spectrum communicate. The method that being used in this study is experimental method with single subject research approach and using the design of A–B pattern. Data collection technique that being used are observation and documentation. And data analysis technique that being used is visual analysis in condition. The results of this research indicate that musical dynamic skills in music subject could be improved by using AAC media. The use of AAC media brings positive impact towards autistic students skills in musical dynamic. Therefore, teachers can apply the using of AAC media on music subject activities in school.

Telepractice is increasingly applied to assessment and intervention for persons with autism spectrum disorders (ASD), and the use of telepractice for delivering augmentative and alternative communication (AAC) services is expanding. To date, no studies have focused on the assessment of communication in children with ASD who are minimally verbal. This case exploration represents a first attempt to apply the clinical assessment approach (also known as Visual Immersion System) developed in the Autism Language Program in the Center for Communication Enhancement (CCE) at Boston Children's Hospital (BCH) through a telepractice service delivery model. In this paper we detail an on-site evaluation, and then describe the application of the various evaluation components to telepractice delivery. Our findings provide preliminary evidence that communication assessment information can be successfully obtained for this population via telepractice. The results demonstrated that the telepractice evaluation took greater time to complete than the on-site evaluation, likely due to both technical and cultural factors. Further study is warranted particularly in the delivery of family instruction materials prior to the evaluation and to quality assurance measures.

Purpose The aim of this research study was to examine common practices of speech-language pathologists (SLPs) who work with children with autism spectrum disorder (ASD) with respect to whether or not SLPs consider processing differences in ASD or the effects of input during their instruction. Method Following a qualitative research method, how SLPs instruct and present augmentative and alternative communication systems to individuals with ASD, their rationale for method selection, and their perception of the efficacy of selected interventions were probed. Semistructured interviews were conducted as part of an in-depth case report with content analysis. Results Based on completed interviews, 4 primary themes were identified: (a) instructional method , (b) input provided , (c) decision-making process , and (d) perceived efficacy of treatment . Additionally, one secondary theme, training and education received , was identified . Conclusions Clinicians reported making decisions based on the needs of the child; however, they also reported making decisions based on the diagnostic category that characterized the child (i.e., ASD). The use of modeling when teaching augmentative and alternative communication to individuals with ASD emerged as a theme, but variations in the method of modeling were noted. SLPs did not report regularly considering processing differences in ASD, nor did they consider the effects of input during instruction.

People with ASD often need to access AAC in situations where a tabletop digital device is not practical. Recent advancements have made more powerful, portable, and affordable communication technologies available to these individuals. Proloquo2Go is a new portable augmentative and alternative communication system that runs on an iPhone or iPod touch and can be used to meet the diverse needs of individuals with autism spectrum disorders (ASD) who are ambulatory and have difficulty using speech to meet their full daily communication needs. This article examines Proloquo2Go in light of the best practices in AAC for individuals with ASD such as symbols, visual supports, voice output, and inclusion.
