Communication profiles of two types of gesture using nonverbal persons with severe to profound mental retardation.
A structured communication sampling procedure was used to measure the form and function characteristics of intentional communication acts produced by nonverbal adults with severe mental retardation. Four "contact" subjects (who communicated only with contact gestures) and 4 "distal" subjects (who used distal as well as contact gestures) participated in this study. All subjects produced communication acts that were coded as initiations, and all subjects produced protoimperative-type communication acts. However, contact subjects produced no protodeclarative-type communication acts, whereas all distal subjects produced some protodeclaratives. Distal subjects also produced significantly more repair/recast acts than did contact subjects. Other findings included a tendency for distal subjects to communicate at a higher rate, to initiate more communication acts, and to produce more accompanying wordlike vocalizations than contact subjects. These results are discussed in light of Werner and Kaplan's (1984) concept of distancing as central to symbolization. Implications for future research and for clinical practice are also discussed.
