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 …

Switching between two different tasks normally results in an impairment in people's
performance known as a switch cost, typically measured as an increase in reaction time (RT) …

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 …

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 …

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 …

Switch costs occur whenever participants are asked to switch between two or more task sets.
In a typical task switching experiment, participants have to switch between two task sets …

In 2 experiments, the authors compare stimulus-based versus task-rule-based task
performance. Participants practiced 8 stimulus-response mappings either with or without …

When switching between tasks, participants are sometimes required to use different
response sets for each task. Thus, task switch and response set switch are confounded. In 5 …

When participants are asked to shift between four dimensionally organized tasks which differ
in the type of judgment (numerical vs. spatial) and/or the judgment-to-response mapping …

Three experiments are presented that compare the cost found when switching from one task
to another in two different conditions. In one of them, the tasks switch in predictable …
