Dual-task (DT) situations require additional task-order coordination processes, which are essential for planning, executing, and monitoring the sequence of task processing. These processes rely on an order representation, known as the task-order set, which contains explicit information about the sequence of tasks and is activated during DT processing. Evidence supporting this assumption comes from the observation that, in DT situations with a random task order, performance is typically improved in trials where the task order is repeated (same-order trial) compared to those with a reversed order (different-order trial) relative to the preceding trial. To date, order coordination has only been investigated in multitasking situations involving two tasks. As a result, it remains unclear whether order-set-based control processes are also necessary when performing more than two tasks. To address this question, we conducted five experiments using a novel triple-task paradigm. The applied triple task consisted of two visual and one auditory choice reaction time tasks which were presented in variable order. In all five experiments, we observed improved performance in same-order trials compared to different-order trials. This improvement was evident in task 1, task 2, as well as task 3. These results suggest that order-set based coordination processes are also involved in the processing of more than two tasks. The implications of these findings for future research will be discussed.
