Bottom-up influences on voluntary task switching in different reward contexts?

Acta Psychol (Amst) 2021 May 5;217:103312. Epub 2021 May 5.

Department of Psychology, University of Regensburg, Regensburg, Germany.

In humans, voluntary task switching is susceptible to bottom-up influences like a switch of the target stimulus identity (Mayr & Bell, 2006). A recent study with ants (Czaczkes, Koch, Fröber, & Dreisbach, 2018) has shown that even irrelevant cue changes increase switching behavior, but only if they are presented within a high-reward context. To investigate whether a reward context would also increase switching behavior in response to meaningless cue changes in humans, we conducted two voluntary task switching experiments. Read More
