“…Given that it is chronic Brocaʼs aphasics who exhibit comprehension difficulties on sentences containing syntactic movement, it is impossible to know which part(s) of the lesion are causing the deficit. Furthermore, patients with fluent speech production and lesions that affect posterior brain regions (conduction aphasics) can also exhibit the same sentence comprehension deficits found in Brocaʼs aphasia (Goodglass, Christiansen, & Gallagher, 1993;Caplan, Vanier, & Baker, 1986;Friedrich, Martin, & Kemper, 1985). Thus, an association between syntactic deficits of the sort described by Grodzinskyʼs theory and damage to Brocaʼs area has not been established.…”

The role of Broca's area in sentence processing has been debated for the last 30 years. A central and still unresolved issue is whether Broca's area plays a specific role in some aspect of syntactic processing (e.g., syntactic movement, hierarchical structure building) or whether it serves a more general function on which sentence processing relies (e.g., working memory). This review examines the functional organization of Broca's area in regard to its contributions to sentence comprehension, verbal working memory, and other multimodal cognitive processes. We suggest that the data are consistent with the view that at least a portion of the contribution of Broca's area to sentence comprehension can be attributed to its role as a phonological short-term memory resource. Furthermore, our review leads us to conclude that there is no compelling evidence that there are sentence-specific processing regions within Broca's area.

“…As will be discussed later with respect to a more recent study by Saffran, Schwartz, and Linebarger (1998), patients' ability to process various syntactic structures can be compromised when there are strong semantic factors that lead to the assignment of thematic roles to nouns (as in sailors living on ships rather than vice versa) that contradict those indicated by the syntax. As suggested by Caplan, Vanier, and Baker (1986), it is possible that normal subjects handle such sentences by reviewing a phonological record of the sentence when they detect a discrepancy between a pragmatically based interpretation and one derived from full processing of the syntactic structure. For PV, such a review would be impossible because of her restricted phonological capacity.…”

In the early 1980s, sentence comprehension deficits were attributed to a loss of syntactic knowledge in agrammatic Broca's aphasics and to a short-term memory deficit in conduction aphasics. Findings in the remainder of the decade called both of these claims into question and presented general difficulties for the group study approach. Results from case studies support the representational independence of syntactic and semantic information but the interaction of these knowledge sources during processing. Working memory is still considered to provide critical constraints on sentence comprehension, but the capacity involved appears to be largely independent of the phonological storage involved in word list recall. Current computational approaches to sentence comprehension provide the means of accounting for the interaction of multiple sources of information and working memory requirements, but have yet to be tested against neuropsychological findings.

“…Let us first consider the spatial metaphor. It has been suggested (Kolk and Van Grunsven 1985, Caplan et at. 1986, Caplan and Hildebrandt 1988) that Broca's aphasics suffer from a reduction in the storage capacity of a specialized working memory which holds the intermediate results of parsing.…”

Recently, several investigators have suggested that the parsing system of Broca's aphasics is affected by a resource limitation which could involve (1) a reduction in the size of a syntactic buffer, (2) slow activation of syntactic information, or (3) fast decay of syntactic information. The results of a syntactic-priming experiment, which varied the SOA (stimulus-onset asynchrony: 300, 700 and 1100 ms) between a prime fragment and target presented for lexical decision, provided support for the slow-activation hypothesis. A group of 13 age-matched controls showed syntactic priming, that is, significantly faster response times in the grammatical condition than in the ungrammatical condition, at all three SOAs. A group of 13 Broca's aphasics, on the other hand, showed significant syntactic priming only at the 110 ms SOA.
