How positive and negative feedback following real interactions changes subsequent sender ratings

Area of Science:

• Neuroscience
• Social Psychology
• Cognitive Science

Background:

• Social evaluative feedback shapes self-perception and expectations.
• Understanding neural and behavioral responses to incongruent feedback is limited.

Purpose of the Study:

• Investigate neural and behavioral responses to incongruent social evaluative feedback.
• Examine how feedback incongruent with self-view or expectations modulates brain activity and behavior.

Main Methods:

• Utilized Event-Related Potentials (ERPs) and behavioral measures in 40 participants.
• Manipulated feedback from peers (overly positive/negative) and computer (control).
• Analyzed ERP modulations across the processing stream for feedback incongruence.

Main Results:

• Behaviorally, participants updated expectations and sender ratings based on received feedback.
• ERP analysis revealed distinct mid-latency effects for feedback incongruence with expectation or self-view.
• Both incongruence types increased late ERP amplitudes, correlating with significant sender rating changes.

Conclusions:

• Incongruent social feedback elicits specific mid-latency neural modulations and subsequent updating processes.
• Increased late ERP amplitudes reflect incongruence processing and behavioral adjustments in sender perception.
• This study integrates neural and behavioral data to elucidate evaluative feedback processing.
