Isi artikelThis article describes a series of experiments which show that motor performance suffers when responses in a repeated sequence have variable rather than fixed parameter mappings. In speech production, repeated recitation of the beginning of the alphabet is slowed dra'11atically if the same letters have different stress levels on successive cycles; the same effect holds for vowel-consonant relationships. In keyboard performance, repetitions of finger-tapping sequences suffer if the number of consecutive taps by the same finger changes from cycle to cycle; we call these difficult sequences finger fumblers. Finally, similar effects are obtained with violin playing. The model we develop to account for these results says that parameter values mapped to the subprogram for a response item persist after the subprogram has been executed, and that extra processing is required if a new parameter value must be mapped to the subprogram the next time it is called for. This account is consistent with the view that motor programs for forthcoming actions' are prepared by editing motor programs for actions that have just been completed. Because our results are similar to interference effects in traditional memory studies, we also suggest that similar mechanisms underlie storage and retrieval of motor responses and symbolic materials.
