This paper investigates the effect of the repetition of phonological elements on accuracy in spontaneous language production. Using a corpus of naturalistic speech errors, it is shown that repetition of a whole segment doubles the error rate on the second token (a perseveratory effect), for onset consonants, vowels, and coda consonants; the effect…

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)

Dell, Burger, and Svec (1997) proposed that the proportion of speech errors classified as anticipations (e.g., "moot and mouth") can be predicted solely from the overall error rate, such that the greater the error rate, the lower the anticipatory proportion (AP) of errors. We report a study examining whether this effect applies to changes in error…

Reductions and timing errors were 2 major signing disruptions observed in a 64-year-old deaf signer with Parkinson's disease; these errors are phonetic rather than phonological in nature. Error analysis yields information about sign prosody and American Sign Language phonological representation. (Contains 54 references.) (JP)
