Repetition is a central phenomenon of behavior, and researchers have made extensive use of it to illuminate psychological functioning. In the language sciences, a ubiquitous form of such repetition is "structural priming," a tendency to repeat or better process a current sentence because of its structural similarity to a previously experienced…

Summarizes and evaluates research on aphasia, and indicates problem areas that must be studied. (52 references) (CFM)

The justification for Kean's (EJ 165 107) analysis of agrammatism as a phonological disorder rests on a certain specific theory of the structure of human language faculty, which is summarized. Simply proposing a competing analysis based on a distinct theory does not falsify the hypotheses. However, Kean's claims are subject to empirical…

Two claims essential to Kean's interpretation (EJ 165 107) that Broca's aphasia results in a phonological disorder rather than a syntactic or morphological disorder are disputed. The claim that the plural morpheme is derivational, and the postulation of the notion of the phonological word are shown to have no linguistic motivation. (Author/RD)

A discussion of grammatical disorders in aphasia considers an area of ambiguity. In the work of one researcher, impairment of logico-grammatical relations is associated with semantic aphasia, not efferent-motor aphasia. In Western studies, efferent-motor aphasia is associated with impaired comprehension and production of grammar. In order to…

Investigated the source of agrammatic aphasic patients' difficulty comprehending semantically reversible sentences. Found approximately equal distributions of three distinct patterns. Results conflict with explanations of comprehension failure which state that a single pattern of performance on sentence structures characterizes comprehension of…
