Augmentative and alternative communication (AAC) technologies offer the potential to provide children who have complex communication needs with access to the magic and power of communication. This paper is intended to (a) summarize the research related to AAC technologies for young children who have complex communication needs; and (b) define priorities for future research to improve AAC technologies and interventions for children with complex communication needs. With the realization of improved AAC technologies, young children with complex communication needs will have better tools to maximize their development of communication, language, and literacy skills, and attain their full potential.

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.

The return rate for participants was small, and it is difficult to generalize the results. However, the majority of respondents reported that they could have benefited from additional training in the area of autism. As a result, it may be necessary to consider strategies for providing this training.

The current generation of augmentative and alternative communication (AAC) technologies is largely based on conceptual models of adults who are not disabled (J. Light & P. Lindsay, 1991). As a result, there is a large "cost of learning" placed on young children. This paper presents the results of a study designed to investigate the learning demands of dynamic display systems that differed in system layout and language organization for children approximately 2 1/2 years old (2 years 5 months to 2 years 11 months). Thirty typically developing children were asked to locate 12 vocabulary items within a play context of a birthday party. Ten children were randomly assigned to each of 3 system approaches: vocabulary in a grid format organized taxonomically, vocabulary in a grid format organized schematically, and vocabulary in an integrated scene organized schematically. The children participated in 4 learning and testing sessions and 1 generalization session. Results indicated that the children performed poorly in all conditions but were able to locate more vocabulary items in the schematic scene condition than the taxonomic grid or schematic grid conditions. There was evidence that the children failed to generalize their knowledge of the vocabulary to facilitate learning of novel vocabulary items. The current design of AAC dynamic display systems appears to be inappropriate for very young children. Rather than relying solely on technology for these young children, early intervention should target multiple modes of communication. AAC technologies should be redesigned to reduce learning demands. Results are discussed with implications for practice and suggestions for future research.
