Retrieving a word in a sentence requires speakers to overcome syntagmatic, as well as paradigmatic interference. When accessing "cat" in "The cat chased the string", not only are similar competitors such as "dog" and "cap" activated, but also other words in the planned sentence, such as "chase" and "string". We hypothesise that both types of…

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)

Reports on a case study where an individual's errors in productive tasks are analyzable as functions of morphological properties of the target and/or the response. It is shown that the morphological errors are explainable in the context of a two-stage retrieval system applying to both affixed and unaffixed words. (33 references) (JL)

Studied a bilingual Italian-English aphasic patient who was very poor in categorizing Italian nouns for grammatical gender in explicit metalinguistic tasks, and was at chance when gender could not be inferred from the word's phonology. However, she showed a good ability to modify adjectives to match the gender of nouns in a task that involved…

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…

This article explores a model of lexicalisation based upon the constraints that lexicalisation is an interactive process and that it takes place in two stages. The article examines in depth the time-course of normal lexicalisation, speech error data, and the cognitive neuropsychology of speech production. (16 references) (CK)

Summarizes the results of Finnish studies dealing with single-word experiments with aphasics as well as lexical decisions and eye-movement registration tests performed on normals. It then proposes a processing model for Finnish nouns, Stem Allomorph/Inflectional Decomposition (SAID), which predicts that both inflected and productive derived forms…

Notes that prior assumptions that writing requires phonological mediation has been questioned due to the observation that on tasks requiring the production of spoken and written responses on the same naming attempt, some aphasic subjects produce different words. The data suggest that phonological and orthographic word forms can interact. (53…

An aphasic patient is described as one whose poor repetition of sentences and of lists of words contrasts with his or her surprisingly good performance on immediate problem recognition tasks. This result is interpreted as suggesting a distinction between phonological input and output buffers. (41 references) (Author/LB)

Examines semantic errors produced by normal and aphasic speakers on a picture naming test for their phonological similarity to the targets they replace. A second study examines phonological relationships within sets of semantically related words and shows there is no tendency for these words to share phonological characteristics. (35 references)…

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…

Different models of spoken word production make different predictions regarding the extent of effects of certain word properties on the output of that model. This article examines these predictions with regard to the effect of these variables on the production of semantic and phonological errors by aphasic subjects. (60 references) (Author/CK)

Two studies are reported in which the following theory is tested: the agrammatic sentence form that is observed in the spontaneous speech of Broca's aphasics is attributable to the selection of elliptical syntactic structures in which the slots for many of the closed-class words that appear in complete sentences are lacking. (54 references)…

Notes that in linguistic theory, phenomena previously handled by a separate grammatical component have been moved into the lexicon and that in some theories, the contrast between grammar and the lexicon has vanished. Concludes that the case for a modular distinction between grammar and the lexicon has been overstated and that the evidence to date…

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…
