Approach and avoidance movements modulate value-driven attentional capture.

Area of Science:

• Cognitive Psychology
• Neuroscience
• Visual Perception

Background:

• Value-driven attentional capture describes how salient visual features linked to high monetary rewards attract attention.
• Rewards are often contingent on actions, suggesting a potential interaction between action, reward, and attention.

Purpose of the Study:

• To investigate how approach and avoidance movements modulate value-driven attentional capture.
• To determine if the history of action-reward associations influences visual selection.

Main Methods:

• Three experiments were conducted to examine the effect of movement type (approach vs. avoidance) on attentional capture by reward-associated cues.
• Participants' visual attention was measured in response to visual stimuli previously linked to different reward levels achieved through specific movements.

Main Results:

• Attentional capture by high-reward cues occurred only when rewards were obtained via approach movements.
• Conversely, low-reward cues captured attention more when rewards were obtained via avoidance movements.
• Movement types alone, without associated rewards, did not modulate attentional capture.

Conclusions:

• Visual selection is interactively modulated by the history of action and reward.
• Compatible action-reward pairs, where approach is linked to high reward and avoidance to low reward, prioritize visual selection.
• These findings highlight a novel mechanism by which motor actions shape attentional processing.
