Presents data from a patient with a progressive fluent aphasia, who exhibited a severe verbal impairment but a relatively preserved access to knowledge from pictures. Argues for a distributed, multi-modality system for semantic memory in which information is stored in different brain regions and in different representational formats. (Author/VWL)

In this paper, we reconsider some of the processes that distinguish production and comprehension. In particular, we discuss the specific forms of thinking involved in each: "thinking for speaking" and "thinking for listening" (Black and Chiat, 2000; Slobin, 1996). We argue that thinking for speaking (or for any form of language output) crucially…

Examines Nickels's claim that interactive models of lexical access in speech production cannot account for naming data from a group of anomic patients. This paper reiterates that the behavior of connectionist models is not easily predictable without running the appropriate simulations, and discusses the role of frequency in lexical access in…

The functional architecture of the verbal processing resource system was studied by testing aphasic patients in Canada and Boston for their abilities to use syntactic structure in sentence comprehension in isolation and under dual-task conditions. Results indicate that the processing resource system underlying syntactic processing is separate from…

Compares speech-related (coverbal) gestures in brain-damaged patients (aphasics and visuo-spatial deficits) and in matched controls. Results suggest ideational gestures probably facilitate word retrieval and reflect transfer of information between propositional and non-propositional representations during message construction, and that conceptual…
