Measuring the cognitive and neural sequelae of switching between tasks permits a window
into the flexible functioning of the executive control system. Prolonged reaction times (RTs) …

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 …

A hybrid blocked and event-related functional magnetic resonance imaging (fMRI) study
decomposed brain activity during task switching into sustained and transient components …

Alternating between task sets involves detection that the current task set is unfavorable,
initiation of a change in set, and application of the new task set while fine-tuning to optimally …

We used fMRI to investigate both common and differential neural mechanisms underlying
two distinct types of switching requirements, namely switching between stimulus …

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 …

When a switch between two tasks has to be carried out, performance is slower than in trials
where the same task is performed repeatedly. This finding has been attributed to time …

Cognitive control is required to regulate interactions between brain regions to produce
effective, purposeful behavior. We used functional magnetic resonance imaging to …

An ongoing controversy concerns whether executive control mechanisms can actively
reconfigure the cognitive system in preparation for switching to a new task set. To address …

Cognitive control processes refer to the ability to flexibly adapt one's thoughts and actions in
the pursuit of an internal goal. Task preparation is a central aspect of cognitive control and …
