Adaptive control forms the basis of cognitive and behavioral flexibility. It is sensitive to normal aging and its malfunction is closely related to neurological and psychiatric conditions. In general, human beings have the astonishing ability to flexibly adapt action and thought in response to changing requirements from the environment. At the same time, they can be surprisingly stuck in set, for example when they continue using a formerly successful but no longer adaptive processing strategy. Such stuck-in-set phenomena, originally reported in problem solving tasks (Luchins, 1942) are not restricted to neuropsychological abnormalities like perseveration in frontal lobe patients but have recently also been reported for control strategies in context processing- and response conflict-tasks in healthy individuals (e.g., Abrahamse, Duthoo, Notebaert, & Risko, 2013; Hefer & Dreisbach, 2017). In this research project, we intend to investigate two so far highly neglected phenomena that expose a weakness of the much-vaunted cognitive flexibility: (1) The asymmetrical costs when switching between a shielded and a more relaxed mode of control, which show that it can be harder to let go from a shielding control mode and switch to a more relaxed control mode than vice versa. And (2) the observation that the flexibility to adapt control to different context demands is further limited by the volatility and frequency of context changes. The importance of adaptive control for cognitive and behavioral flexibility highlights the need for understanding the underlying cognitive mechanisms (e.g., the flexible (dis)engagement of different control states), which may offer fertile grounds for subsequent translational research.
