Purpose: Directed scanning and group-item scanning both represent options for increased scanning efficiency. This investigation compared accuracy and speed of selection with preschoolers using each scanning method. The study's purpose was to describe performance characteristics of typically developing children and to provide a reliable assessment…

Management of inappropriate behaviour is a major priority in special education. Evidence-based practice dictates that interventions to reduce inappropriate behaviour should be evaluated at the individual level to demonstrate their efficacy in the classroom. This study illustrates the evaluation of an evidence-based procedure (response…

The study investigated the impact of mastery of the Picture Exchange Communication System (PECS) to Phase III, on the communications of children with autism. Children aged between 3 and 7 years, formed a PECS intervention group and a non-intervention control group. The intervention group received 15 h of PECS teaching over 5 weeks. Three 2-h…

Background: Augmentative and alternative communication (AAC) systems are commonly used to support children with complex communication needs in Australian preschools. However, such systems will only be effective if they contain words and messages that adequately meet these children's communication needs. The aim of this study was to identify the…

Purpose: This research examined how the color distribution of symbols within a visual aided augmentative and alternative communication array influenced the speed and accuracy with which participants with and without Down syndrome located a target picture symbol. Method: Eight typically developing children below the age of 4 years, 8 typically…

Through About Us service, the Sussex County Council is providing more innovative and more creative ways of engaging and supporting adults with learning disabilities. About Us provides nationally accredited life-skill and vocational training in a wide range of subjects using an innovative approach involving pictorial worksheets, witness statements,…

Research on graphic symbol learning suggests that symbols with a greater visual resemblance to their referents (greater iconicity) are more easily learned. The iconicity hypothesis has not yet been explored within the intervention protocol of the Picture Exchange Communication System (PECS). Within the PECS protocol, participants do not point to a…

Children with disabilities are reported to experience a high degree of directive parent interaction compared to typically developing children because of poor communicative or task skills. This study examines relationships between parent behaviors (directiveness and contingency) and child skills (language and motor) for children with physical or…

Two young boys with autism who used the picture exchange communication system were taught to solve problems (improvise) by using descriptors (functions, colors, and shapes) to request desired items for which specific pictures were unavailable. The results of a multiple baseline across descriptors showed that training increased the number of…

This study uses a best-evidence synthesis method to investigate the secondary effects of various antiepileptic drugs (AEDs) and their implications on augmentative and alternative communication (AAC) processes. Epilepsy is a common serious neurological disorder, a concomitant condition in individuals with severe developmental and intellectual…

The purpose of this study was to examine the effects of Functional Communication Training (FCT) and a Voice Output Communication Aid (VOCA) on the challenging behavior and language development of a 4-year-old girl with autism spectrum disorder. The participant's mother implemented modified functional analysis (FA) and intervention procedures in…

The purpose of this study was to determine the impact of training paraeducators on (a) paraeducator prompting use of augmentative communication (AAC) systems, (b) paraeducator responding to student requests, (c) student use of AAC, and (d) student problem behavior via a series of multiple probe designs. Participants were three paraeducators and…

The current study investigated the effectiveness of an integrated word identification and communication intervention for children with complex communication needs. Using a nonconcurrent, multiple baseline design, the study involved three participants who completed 75 lessons across 4 to 6 weeks of instruction. All three participants improved their…

We describe evidence and intervention strategies for parents, educators, and researchers who seek to enhance communication and literacy in children with Rett syndrome (RS). Four girls with RS and their mothers videotaped their storybook interactions at home for 4 months. Parent-child storybook interactions were coded for child behaviors (e.g., use…
