Abstract

Study of the influence of sign characteristics on sign acquisition and retention has resulted in the accumulation of a sizable body of literature over the past decade. This literature can be divided into three categories according to the type of sign characteristic under study: (a) phonological parameters, which describe the basic formational units of signs; (b) motoric dimensions, which describe other formational features of signs that do not have the status of parameters per se; and (c) conceptual features, which emphasize the semantic information conveyed by sign referents, although consideration may also be given to sign formation. The literature relevant to each category will be reviewed to determine the theoretical and the clinical import of characteristics subsumed by each. Of concern theoretically is the contribution each characteristic makes to the processes of learning and memory. Of concern clinically is the potential usefulness of each characteristic in selecting an initial lexicon for mentally retarded learners that will maximize their success early in sign training.
