How to Correct a Task Error: Task-Switch Effects Following Different Types of Error Correction

JEPLMC Volume 36, Number 4, ISSN 0278-7393


It has been proposed that switch costs in task switching reflect the strengthening of task-related associations and that strengthening is triggered by response execution. The present study tested the hypothesis that only task-related responses are able to trigger strengthening. Effects of task strengthening caused by error corrections were considered. Recent findings suggest that errors lead to erroneous task strengthening, which, however, can be reversed by immediate error correction (Steinhauser & Hubner, 2006). In three experiments, the present study examined whether this effect is also obtained when task responses and correction responses share the same response categories but are assigned to different hands or different response modalities (manual vs. vocal). Results indicated that only corrections with the same hand but not corrections with the alternative hand or a different response modality can reverse erroneous task strengthening. These results suggest that only the execution of task-related responses triggers task strengthening, whereas the activation of task-related response categories is not sufficient.
