Are self-caused distractors easier to ignore? Experiments with the flanker task

Area of Science:

• Cognitive Psychology
• Neuroscience
• Attention Studies

Background:

• Action-outcome learning is crucial for goal-directed behavior.
• Understanding how learning affects attention to irrelevant stimuli is key to cognitive control.
• Previous research has explored associative learning but its impact on distractor processing requires further investigation.

Purpose of the Study:

• To investigate the relationship between action-outcome learning and the ability to ignore distractors.
• To determine if the complexity of distractor features modulates the effect of learning on attentional allocation.
• To explore whether associative learning mechanisms extend beyond motor actions to perceptual learning.

Main Methods:

• Four experiments involving acquisition and test phases with varying action-outcome contingencies.
• Manipulation of distractor features (color, distance, compatibility) dependent on participant actions.
• Inclusion of a perceptual sequence learning experiment using visual cues instead of actions.

Main Results:

• Exposure to action-outcome contingencies significantly altered distractor cost for simple features (color, distance).
• Complex or relational distractor features (target-distractor compatibility) were unaffected by contingency learning.
• Similar effects on distractor cost were observed in perceptual sequence learning, indicating a broader role for associative learning.

Conclusions:

• Associative learning, particularly action-outcome learning, plays a role in modulating attention to task-irrelevant events.
• The impact of learning on distractor processing is dependent on the complexity of the distractor features.
• Mechanisms of associative learning are not exclusive to actions and can influence attention in perceptual learning tasks.
