Attentional capture alters feature perception.

Area of Science:

• Cognitive Psychology
• Neuroscience
• Visual Perception

Background:

• The modern world presents constant distractions.
• Previous research on distractors focused on reaction time, accuracy, and oculomotor capture.
• The impact of distractors on fundamental target feature representations remains less understood.

Purpose of the Study:

• To investigate whether attentional capture by distractors alters target feature representations.
• To determine if participants are aware of these altered feature representations.
• To explore the nature of feature-binding errors induced by distractors.

Main Methods:

• Utilized a continuous report task.
• Introduced a novel confidence range report paradigm.
• Presented distractors alongside targets to observe effects on perception.

Main Results:

• Identified two types of feature-binding errors: swapping errors and repulsion.
• Swapping errors (misreporting distractor color as target color) occurred without awareness when attention was strongly captured.
• Repulsion (perceptual distortion away from distractor color) occurred when participants resisted attentional capture.

Conclusions:

• Attentional capture by distractors fundamentally alters feature perception, not just attention allocation.
• Distractors can induce feature-binding errors, including unaware swapping and repulsion.
• These findings reveal striking ways capture impacts visual perception.
