The capacity theory of sentence comprehension: Critique of Just and Carpenter (1992).

The article outlines an alternative to the capacity theory, according to which the unconscious, obligatory operations involved in assigning the syntactic structure of a sentence do not use the same working memory resource as that required for conscious, controlled verbally mediated processes.

Abstract

The authors review M.A. Just and P.A. Carpenter's (1992) "capacity" theory of sentence comprehension and argue that the data cited by Just and Carpenter in support of the theory are unconvincing and that the theory is insufficiently developed to explain or predict observed patterns of results. The article outlines an alternative to the capacity theory, according to which the unconscious, obligatory operations involved in assigning the syntactic structure of a sentence do not use the same working memory resource as that required for conscious, controlled verbally mediated processes.
