  • Title: Adaptive control of response preparedness in task switching.
    Author: Steinhauser M, Hübner R, Druey M.
    Journal: Neuropsychologia; 2009 Jul; 47(8-9):1826-35. PubMed ID: 19428414.
    Abstract:
    When rapidly switching between two tasks, bivalent stimuli can accidentally trigger the previously executed and therefore still activated response. Recently, it has been suggested that behavioral response-repetition effects reflect response inhibition that reduces the risk of such erroneous response repetitions. The present study investigated neural correlates of this inhibition process using lateralized readiness potentials (LRP). In three experiments, we demonstrate a response-switch bias emerging during the preparatory interval which is independent of task sequence (Experiment 1), which is linked to task preparation (Experiment 2), and which is present only under task-switching conditions (Experiment 3). These results suggest that the bias reflects a control process that adaptively regulates response preparedness.
