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)

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…

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)

Presents the results of three experiments investigating the time course of grammaticality judgement. The high correlations among the experiments suggest that the incremental tasks assigned were tapping into the same decision-making process as is found online. The article discusses the findings' implications for the error types that do and do not…
