Self-paced preparation for a task switch eliminates attentional inertia but not the performance switch cost.

The cost of a voluntary task switch.
Task-switching paradigms are widely used to study executive control. However, standard paradigms may not require active control to switch tasks. We examined voluntary task switching by having subjects choose which task to perform on a series of bivalent stimuli. Subjects performed parity or magnitude judgments on single digits. Instructions were to perform the two tasks equally often and in a r...
متن کاملThe influence of cue-task association and location on switch cost and alternating-switch cost.
Task-switching performance is strongly influenced by whether the imperative stimulus uniquely specifies which task to perform: Switch cost is substantial with bivalent stimuli but is greatly reduced with univalent stimuli, suggesting that available contextual information influences processing in task-switching situations. The present study examined whether task-relevant information provided by ...
متن کاملThe μ Switch Region Tandem Repeats Are Important, but Not Required, for Antibody Class Switch Recombination
Class switch DNA recombinations change the constant (C) region of the antibody heavy (H) chain expressed by a B cell and thereby change the antibody effector function. Unusual tandemly repeated sequence elements located upstream of H chain gene exons have long been thought to be important in the targeting and/or mechanism of the switch recombination process. We have deleted the entire switch ta...
متن کاملNo-go trials can modulate switch cost by interfering with effects of task preparation
It has recently been shown that the cost associated with switching tasks is eliminated following 'no-go' trials, in which response selection is not completed, suggesting that the switch cost depends on response selection. However, no-go trials may also affect switch costs by interfering with the effects of task preparation that precede response selection. To test this hypothesis we evaluated sw...
متن کاملTo SWiTCH or not to SWiTCH?
In this issue of Blood, Ware and Helms report results from the Stroke With Transfusions Changing To Hydroxyurea (SWiTCH) study designed to determine whether hydroxyurea is as effective as transfusions in preventing recurrent strokes in children with sickle cell anemia. The finding of strokes in 7 of 67 children receiving hydroxyurea but none in 66 children who received transfusions led the auth...
