With insufficient time to fully prepare for a switch in task, a deterioration in performance on
the first trial of a new task would be expected. The interest of researchers has been captured …

The performance overhead associated with changing tasks (the “switch cost”) usually
diminishes when the task is specified in advance but is rarely eliminated by preparation. A …

Switching between different tasks often increases response time compared to repeated
performance of a task. This switch cost has been thought to reflect either an executive …

In an investigation of task-set reconfiguration, participants switched between 2 tasks on
every 2nd trial in 5 experiments and on every 4th trial in a final experiment. The tasks were …

Four task-switching experiments examined the notion of an exogenous component of task-
set reconfiguration (ie, a process needed to shift task set that is not initiated in the absence …

Reaction time is typically longer on trials on which the task changes. This switch cost is
reduced by the opportunity to prepare for the change before the stimulus onset, but there …

Task-switching studies show no behavioral benefit of partially informative cues. However,
ERP evidence of an early cue-locked positivity elicited by both fully and partially informative …

Switching tasks prolongs response times, an effect reduced but not eliminated by active
preparation. To explore the role of attentional selection of the relevant stimulus attribute in …

Most studies of task-set switching rely on cuing paradigms, in which external cues indicate
the upcoming task. The present study used an entirely predictable task sequence in a …

A task switch typically leads to worse performance than a repetition does. This shift cost can
be reduced with sufficient task preparation time, but a residual cost usually remains. We …
