From the perspective of cognitive psychology, research on cognitive processes and performance has long been based on highly controlled experimental designs with simple stimuli and an instructed response scheme. Whereas this approach is well-suited to study specific cognitive mechanisms, it severely constraints participants in their way of coping with the given tasks. Importantly, this may obscure how humans would naturally perform tasks to efficiently deal with task requirements at hand. One promising avenue to address this issue, however, evolved in the domain of multitasking. Here, human factors research offers an approach that can serve as inspiration for integrating more degrees of freedom, as it focuses on completely self-organized multitasking in more natural settings. In the talk, I will present the Free-Concurrent Dual-Tasking (FCDT) paradigm, which is inspired by human factors research on task performance. In this paradigm, participants are always provided with a view of all ongoing tasks and may freely choose to which task they want to respond. As a result, the FCDT paradigm provides participants with sufficient degrees of freedom, allowing them to develop their own response strategies and response patterns when coping with multiple tasks. However, in conjunction with fine-grained analyses derived from cognitive psychology, the FCDT paradigm retains enough experimental control to investigate which response strategies individuals develop. After a brief description of the paradigm and how these strategies can be identified, I will give an overview of their replicability. Additionally, I will sum up the current findings with respect to FCDT and discuss open avenues.
