Some considerations about the motor requirements of manual signs

Abstract

This paper raises several concerns about some aspects of the motor requirements of manual signs that have appeared in the augmentative and alternative communication (AAC) literature which seem to warrant further investigation. The purpose of the article is: (a) to review what is known and what is proposed about the motor aspects and requirements of manual signs, (b) to raise questions and stimulate thought about some of the proposed and potential relationships, and (c) to suggest directions for future investigations.
