IN concluding a recent work on Language and Perception,George Miller and Phillip Johnson-Laird (1976, p. 690) addressthose interested in studying how people process language when they caution that "a psychology of language should be psychological." Their point is that "if we hope to create something recognizable as a psychological theory of human language, psychological methods and principles should be applied in the same way they are applied to other mental and behavioral phenomena" (p. 691). For communication researchers the statement is a reminder that there are a considerable number of psychological principles emerging from research in cognitive psychology that can prove useful in providing information-processing explanations of communicative phenomena. If communication researchers tackle processing questions, these principles need to be invoked.
