Event-related potential P2 correlates of implicit aesthetic experience

Area of Science:

• Neuroscience
• Psychology
• Cognitive Science

Background:

• Aesthetic experiences involve complex emotional and cognitive processing.
• Differentiating objective aesthetic value from subjective evaluation is crucial for understanding aesthetic responses.
• Event-related potentials (ERPs) offer a sensitive measure of neural activity during cognitive tasks.

Purpose of the Study:

• To investigate affective responses to aesthetic experiences using ERPs.
• To differentiate objective aesthetic value from subjective aesthetic evaluation.
• To explore the role of the P2 component in early aesthetic processing and beauty-related attention bias.

Main Methods:

• An amended oddball task was employed with pendant pictures as frequent non-target stimuli and landscape pictures as rare targets.
• Pendant pictures were categorized as beautiful or less beautiful based on sales ranking from an online store.
• Event-related potential (ERP) measures, specifically the P2 component, were recorded from frontal, central, and parietal scalp areas.

Main Results:

• Less beautiful pendant pictures elicited significantly greater amplitudes of the P2 component compared to beautiful pendants.
• The P2 component, a positive ERP component, was recorded across frontal, central, and parietal regions.
• These findings suggest that emotion arousal occurs early in aesthetic processing and is detectable by the P2 component.

Conclusions:

• The P2 component reflects early emotion arousal during aesthetic perception.
• ERPs, particularly the P2 component, may serve as sensitive measures of beauty-related attention bias.
• Findings suggest P2 can be a reference measure for consumer aesthetic experiences in artwork design and marketing.
