  • Title: Issues in AAC research: how much do we really understand?
    Author: Alant E, Bornman J, Lloyd LL.
    Journal: Disabil Rehabil; 2006 Feb 15; 28(3):143-50. PubMed ID: 16443577.
    Abstract:
    PURPOSE: The purpose of this introductory paper is to provide some overview of and background to the issues that were raised at the Augmentative and Alternative Research Seminar in conjunction with the First Regional AAC conference on 23 February 2004. A group of 45 AAC researchers and professionals convened for one day to discuss some basic research issues in AAC. This paper highlights themes and perspectives that emerged from the research seminar discussions. METHOD: Literature reviews and discussion are used to provide a historical perspective on some of the issues raised. Two focus areas were identified for the purpose of this introductory paper; firstly, terminological issues that arose and secondly common themes that emerged during the paper presentations, discussions and/or written papers. Terminological issues include a brief description of the field of AAC for the benefit of those readers who might not be familiar with the field, whereafter the discussion focuses on the use of the term "complex communication needs" as referring to individuals who use AAC, the differentiation between symbols, signs, symbols sets and systems as well as the terms verbal and nonverbal, pre-linguistic and non-symbolic. The common themes throughout the papers include a discussion on the importance of context in communication, the chicken and egg question (i.e., comprehension and production), issues on multimodality, descriptive strategies for understanding interaction, and the use of typical interaction as a framework for understanding AAC interaction. CONCLUSIONS: In reviewing some of the issues in the field it is apparent that the issues we face now and those faced in AAC during earlier years are similar, however the need for a stronger database is apparent as the approach towards evidence-based practice becomes more prominent. The move to understand the nature of complex relationships in interaction is highlighted, for example, the multiple associations between environment, comprehension as well as the use of multi-modal communication. Whilst it became evident that most of these issues need further research in relation to typical interactions, applications to the field of AAC are most challenging.
