Prefrontal Cortical Mechanisms Underlying Individual Differences in Cognitive Flexibility and Stability
The pFC is critical for cognitive flexibility (i.e., our ability to flexibly adjust behavior to changing environmental demands), but also for cognitive stability (i.e., our ability to follow behavioral plans in the face of distraction). Behavioral research suggests that individuals differ in their cognitive flexibility and stability, and neurocomputational theories of working memory relate this...
متن کاملIndividual differences in cognitive flexibility.
I s it better to be flexible, or persistent? A colleague once said that the secret to success in science is perseveration (no, not mere perseverence—that wouldn’t get you very far at all). Yet we all believe that the highest levels of cognitive function are associated with extreme flexibility—the ability to juggle many things at once and not get hung up on just one. Indeed, this ability to jugg...
متن کاملStochastic Dynamics Underlying Cognitive Stability and Flexibility
Cognitive stability and flexibility are core functions in the successful pursuit of behavioral goals. While there is evidence for a common frontoparietal network underlying both functions and for a key role of dopamine in the modulation of flexible versus stable behavior, the exact neurocomputational mechanisms underlying those executive functions and their adaptation to environmental demands a...
متن کاملComputational and neurobiological mechanisms underlying cognitive flexibility.
The ability to switch between multiple tasks is central to flexible behavior. Although switching between tasks is readily accomplished, a well established consequence of task switching (TS) is behavioral slowing. The source of this switch cost and the contribution of cognitive control to its resolution remain highly controversial. Here, we tested whether proactive interference arising from memo...
متن کاملCommon and distinct mechanisms of cognitive flexibility in prefrontal cortex.
The human ability to flexibly alternate between tasks represents a central component of cognitive control. Neuroimaging studies have linked task switching with a diverse set of prefrontal cortex (PFC) regions, but the contributions of these regions to various forms of cognitive flexibility remain largely unknown. Here, subjects underwent functional brain imaging while they completed a paradigm ...
