Augmentative and Alternative Communication (AAC) describes different ways to communicate that supplement or compensate for the impairment of individuals with complex communication needs. AAC can utilize computerized devices, with visual scene display (VSD) or video visual scene display (VVSD) as a communication mode. Recent literature…

Functional communication training (FCT) is an effective intervention for teaching communication responses and reducing challenging behavior. One limitation of FCT is that frequent reinforcement may be impractical or impossible in many situations. Recently, Mitteer et al. published a tutorial in the journal "AAC" that provided video…

Purpose: Aided augmentative and alternative communication (AAC) displays are often designed as symmetrical row--column grids, with each square in the grid containing a symbol. To maximize vocabulary on displays, symbols are often placed close to one another, and background color cuing is used to signal/differentiate symbols across different…

Visual scene displays (VSDs) are becoming an increasingly popular method of message representation within augmentative and alternative communication (AAC) supports; however, design factors can influence the effectiveness of these images as communication supports. One issue that has come to light in recent years is the fact that selecting…

To identify the relationship between non-verbal working memory and graphic symbol selection, this study examined whether the response time to select target symbols in a sentence construction task differed between two groups: a high non-verbal working memory group and a low non-verbal working memory group. The interaction effect between non-verbal…

Individuals with low functioning autism spectrum disorders (LFASD) who demonstrate significant cognitive and communication needs benefit from using technology for learning graphic symbols for enhancing participation. This study investigated if an iPad application would increase identification of graphic symbols by children and adults with LFASD.…

A study evaluated the use of computer-based video anchors to increase photograph recognition by two students with severe intellectual disabilities. A substantial increase was made in the number of photographs correctly selected with the computer program with results generalizing to selection of photographs on each participant's augmentative…
