Imagery and Language
This chapter extends the dual-coding model to psycholinguistic phenomena. The central question is whether such an approach provides a viable alternative, or the foundation of an eventual alternative, to the associationistic and linguistic conceptions discussed in the last chapter. The first of three sections devoted to the issue reviews the dual-coding theory with specific reference to its relevance to psycholinguistic problems. The second reviews the available empirical evidence on the role of imaginal and verbal symbolic processes in language comprehension, production, and memory. The final section presents some speculative views concerning the implications of the model for such linguistic phenomena as poetry and metaphor. In view of its novelty as a theoretical construct in contemporary psycholinguistics, imagery will receive most of the attention throughout, but always with due regard for its conceptual status in the twoprocess model.
