[DESCRIPTION]
Cognitive Flexibility, the ability to adapt behavior and thought to the environment is one of the most important aspects of human cognition. A classical paradigm to study cognitive flexibility is the task-switching paradigm. These paradigms require the participant to switch between two or more relatively simple tasks continuously. Results consistently show that switching between tasks results in task-switching costs (TSC) in the form of increased reaction times and error likelihood following a switch. These effects have been shown in a wide array of circumstances, however, several factors have yet to be investigated within the context of cognitive flexibility.
Similarity is an important factor for research within cognitive flexibility as most fundamental research has only focused on very similar tasks, rather than being ecologically valid. Beyond similarity conflict, which is elicited when a participant is confronted with incongruent information as to the correct response during a task, needs to also be accounted for. Finally, in the context of increasing ecological validity mental fatigue with its established effect on cognitive flexibility needs to also be taken into consideration.
