abstract="In a recent article, Rosenbaum, Kenny, and Derr (1983) described a hierarchical storage and execution model for a class of repetitive, discrete response sequences. With a few modifications, this model can match the performance of subjects performing sequences from this class. The authors claimed that this provides an &quot;existence proof&quot; for hierarchical control during movement execution, at least for these sequences. My purpose is to show by counterexample that this claim is too strong. I present a logogen activation model for the rapid execution of stored motor sequences which assumes that (a) logogens corresponding to responses are activated via association and repetition; (b) activation decays; and (c) interresponse time is inversely related to activation of the correct response at each position in the sequence. This model can also fit the results of Rosenbaum et al. A much richer data base, designed to discriminate between competing formulations, will be needed to prove the existence of the hierarchical, tree-traversal control process proposed by Rosenbaum et al.<p /><p>Language: en</p>",
