Summary
Task preparation can be empirically separated from task execution. Our experiments show that precueing a task, even with an intervening task, allows for specific preparation, minimizing transition costs.
Area of Science:
- Cognitive Psychology
- Human Performance
Background:
- Recent studies question the distinct separation of task preparation and execution.
- Understanding task preparation is crucial for optimizing cognitive performance.
Purpose of the Study:
- To empirically investigate the separability of task preparation and execution.
- To determine if precueing a task allows for preparation independent of its immediate execution.
Main Methods:
- Two experiments were conducted, separating task precueing from execution using an intervening task.
- Imperative stimuli associated with competing tasks were used for the precued task.
- Interference effects on the intervening task and transition costs were measured.
Main Results:
- The intervening task showed specific interference related to the precued task, indicating preparation occurred during precueing.
- Transition costs between tasks were minimal and independent of the interval, suggesting early preparation.
- Interference resolution occurred at the level of individual task features.
Conclusions:
- Task preparation, initiated by precueing, is empirically separable from task execution.
- Significant preparation for a task can occur before its actual execution, even with competing demands.
- Cognitive control mechanisms resolve interference by focusing on individual task features.
