Do item-specific control adjustments transfer across response modalities?

Area of Science:

• Cognitive Psychology
• Neuroscience

Background:

• Individuals learn to associate cues with attentional demands, enabling reactive control adjustments.
• A key question is whether this learned control transfers to situations where cues are no longer predictive.

Purpose of the Study:

• To investigate if learning-guided control, acquired through one response modality, transfers to a different response modality.
• To examine the conditions under which control settings generalize across response modalities.

Main Methods:

• Utilized a picture-word Stroop task with an item-specific proportion congruence manipulation for training.
• Assessed transfer of learned control settings from manual keypress responses to vocal responses.
• Compared transfer effects when training and transfer items were separated (Experiment 1) versus intermixed (Experiment 2).

Main Results:

• No transfer of learning-guided control was observed when training and transfer phases were distinct.
• Transfer of learning-guided control was evident when training and transfer items were intermixed within experimental blocks.
• Findings suggest that the presentation structure influences the generalization of control settings across response modalities.

Conclusions:

• Learning-guided control settings can generalize across different response modalities, but this transfer is condition-dependent.
• Modality-specific processes and the temporal separation of training and transfer items play a crucial role in modulating transfer.
• These findings have implications for understanding automaticity and the flexibility of cognitive control.
