ABSTRACT
Alvin Liberman and his colleagues (e.g., Liberman & Mattingly, 1985) proposed that speech production and speech perception are "different modes of the same mechanism." The focus of the panel discussion is whether this proposal can be extended to sentence production and sentence perception. Such an extension was a goal of initial research into the relationship of production and perception to a generative grammar. In the earliest conceptualization of this relationship, the production of a sentence was viewed as essentially identical to its grammatical derivation. Sentence perception was simply the reverse of this process. Thus, sentence production and sentence perception were initially viewed as different modes of the same mechanism; that mechanism being the application of the grammar.
