Angry faces are tracked more easily than neutral faces during multiple identity tracking.

Area of Science:

• Cognitive Psychology
• Neuroscience
• Visual Perception

Background:

• Sustained attention is crucial for daily tasks.
• Emotional facial expressions can influence cognitive processes.
• Previous research on emotion's effect on attention has yielded mixed results.

Purpose of the Study:

• To investigate how emotional facial expressions (anger, happiness) impact sustained attention in a face-tracking paradigm.
• To determine if emotional expressions on target faces versus distractor faces differentially affect tracking performance.
• To explore the role of visual features and emotional information in attention modulation.

Main Methods:

• Participants engaged in a multiple-identity and object tracking task involving moving target and distractor faces.
• Emotional expressions of faces (angry, happy, neutral) were manipulated.
• Tracking accuracy was measured by participants' ability to locate target faces post-movement.

Main Results:

• Tracking performance significantly improved when target faces displayed angry expressions compared to neutral ones.
• Angry distractor faces did not influence tracking performance.
• The facilitatory effect of angry target faces persisted even when faces were inverted or visual details were task-irrelevant.
• Happy faces showed only weak, suggestive effects on both target facilitation and distractor interference.

Conclusions:

• Angry facial expressions on target faces can enhance sustained attention, likely through increased vigilance.
• This attentional benefit is influenced by both the emotional content and visual characteristics of the angry faces.
• Emotional expressions play a significant role in modulating visual attention, with anger having a particularly potent effect on target detection.
