Making mistakes in public: Being observed magnifies physiological responses to errors.

Area of Science:

• Neuroscience
• Social Psychology
• Cognitive Science

Background:

• Humans often perform tasks under public observation.
• Social presence can influence feedback evaluation and learning.
• The neural mechanisms of observer-induced behavioral changes are not well understood.

Purpose of the Study:

• To investigate how the presence of observers modulates neural representations of errors and losses.
• To examine the effects of social observation on event-related potentials (ERPs) and spectral perturbations (ERSPs) during a gambling task.

Main Methods:

• Utilized a gambling task with two conditions: participants performing alone versus being observed by two others.
• Employed electroencephalography (EEG) to record event-related potentials (ERPs) and event-related spectral perturbations (ERSPs).
• Analyzed neural signals, including feedback-related negativity (FRN) and late positive potential (LPP), and theta power.

Main Results:

• The presence of observers enlarged the difference in feedback-related negativity (FRN) amplitude between error and correct feedback.
• A marginally enhanced amplitude difference for the late positive potential (LPP) between error and correct feedback was observed when participants were being observed.
• Theta power was significantly enhanced in the observed condition compared to the alone condition.

Conclusions:

• Neural representations of errors are significantly influenced by the presence of others.
• Social observation modulates key electrophysiological markers of feedback processing, including FRN and LPP.
• Enhanced theta power suggests altered cognitive or emotional processing under social observation.
