Talk 1: Self-organized task scheduling in multitasking/ Dr. Andrea
Kiesel
Research often focused on the costs when multitasking. Yet multitasking might also be beneficial due to constraints in the environment. For example, multi-step tasks often entail waiting times until one process is finished – like waiting for the water to boil when cooking tea. In a variant of the voluntary task-switching procedure, we explored whether and how participants adapt task selection to their individual taskswitching performance limitations
(switch costs) with such externally induced waiting times. In several experiments, we observed that participants equally trade off switch costs against increasing time waiting for the stimulus needed for a task repetition. In a variant of the task, we manipulated motor effort for task repetitions and observed that participants switch tasks more with increasing force required for responding in task repetition trials.
Thus, participants considered their individual cognitive and motor costs when selecting tasks, demonstrating a close link between task selection and task performance.
