The word-position similarity constraint on segmental speech errors: Further experimental results
Stefanie Shattuck‐Hufnagel · The Journal of the Acoustical Society of America · 1983
In earlier experiments it was shown that speech errors involving the interaction of two target segments are governed by a word-position similarity constraint: two segments are more likely to interact in an error if they are word initial then if they are stressed-syllable initial or simply syllable initial. Further experiments have shown that this effect (1) is more pronounced for nonwords than for words, suggesting that the phenomenon arises during the computation of a short-term representation of the units of the utterance rather than during lexical access, and (2) is found in sentence generation tasks as well as in the original tongue-twister repetition tasks, making an explanation in terms of memory constraints less likely and an account in terms of production planning more likely.
