The Action and Cognition Lab at the University of Iowa supports research investigating a range of topics, most of which fit under the umbrella term response selection. Response selection processes enable us to transform sensory information into goal-directed actions.  We approach this topic from a variety of perspectives, including motor learning, bimanual coordination, and dual-task interference using a range of cognitive neuroscience methodologies.  Although this work represents a diverse set of findings, a central theme is that response selection processes act on flexible representations based on codes that incorporate action goals.  These codes are abstract in the sense that they are determined by task demands rather than movement parameters.  Therefore, interactions among possible responses, whether they are manifest in performance benefits derived from sequence learning or performance costs derived from response competition, are mediated by the individuals’ goals and their conceptualization of their actions.
