Wordshape errors in language production

Errors in natural speech that crucially involve the shape of the target word, i.e. interact in some way with the number of consonants and vowels in the word and their relative positioning, are examined in detail. It is shown that context highly constrains the rate of such errors. The data implicate a distinction between a segment level that encodes fine phonemic distinctions and a wordshape level with a course encoding. Implications for the representation of language and cognitive processing in language production are explored.
