Abstract

It is well documented in the augmentative and alternative communication (AAC) literature that many children exhibit difficulty identifying visual-graphic symbols on aided communication displays during the communication process. Researchers have identified a number of variables that influence children's abilities to identify these symbols. Some of these variables include the type of symbol used, language organization, display type, and the actual physical dimensions of symbols such as size and color. One important variable that has not been considered or evaluated in AAC display designs is children's developmental visuospatial and temporal memory abilities. In this article, we will discuss the role that developing visuospatial and temporal memory may play in the identification, location, and sequence of visual-graphic symbols. We will review basic terminology regarding memory function related to object-location memory and present clinical considerations for easing the memory and attentional processing demands of selecting visual-graphic symbols.
