Implication

Experimental study demonstrates residual reaction time costs in adults during predictable task switching, indicating that full cognitive reconfiguration requires direct stimulus exposure.

Key Points

To investigate whether advance preparation can completely eliminate performance costs during predictable switching between simple cognitive tasks.
Conducted five experiments where participants alternated between two classification tasks every second trial, and a sixth experiment alternating every fourth trial.
Required participants to categorize digit pairs as even/odd or letter pairs as consonant/vowel across varying response-stimulus intervals up to 1.2 seconds.
Increasing the response-stimulus interval up to 0.6 seconds substantially reduced reaction time switch costs, demonstrating partial advance task reconfiguration.
A large asymptotic reaction time cost persisted on the first trial of a new task even with 1.2 seconds of preparation time.
Reaction times and switch costs increased further when stimuli contained characters associated with the competing, currently irrelevant task.
