Article Commentary: Social Constructivism,Positivism,and Facilitated Communication

Facilitated communication, a technique that is said to enhance the communicative abilities of individuals with severe language impairments, has engendered much controversy. Biklen and Duchan (1994) and Green and Shane (1994) present two sides of this controversy. Biklen and Duchan argue that from a constructivist's perspective, the primary issue is the underlying cultural presuppositions regarding mental retardation and science rather than the efficacy of facilitated communication. Green and Shane present research evidence challenging the efficacy of facilitated communication within a positivist's framework. We present a brief review of science as viewed through positivists' and constructivists' lenses. Using the framework of social constructivism adopted by Biklen and Duchan, we disagree with them on three points: (a) even though the process of constructing scientific knowledge is strongly affected by human social, emotional, and cognitive processes, it also involves matters of fact that cannot be ignored; (b) social constructivists' accounts of science can be accepted as descriptive without being prescriptive; (c) although we cannot prove that belief systems, including positivism and social constructivism, are true or false in the larger sense, belief systems have differential consequences for technological changes of the type that are valued by persons with severe impairments of communication.
