Long-term academic stress increases the late component of error processing: an ERP study.

Area of Science:

• Neuroscience
• Cognitive Psychology
• Stress Research

Background:

• Long-term stress impacts brain function and cognition.
• Limited research exists on stress effects on neural error processing (event-related potentials - ERPs).

Purpose of the Study:

• To investigate how academic stress influences error processing via ERPs.
• To examine the modulation of error related negativity (Ne/ERN) and error positivity (Pe) by stress.

Main Methods:

• Forty-one male students preparing for exams and 20 controls performed a Go-NoGo task.
• Electroencephalography (EEG) recorded event-related potentials (ERPs) during the task.
• Perceived stress levels and exam importance were self-reported.

Main Results:

• Exam group reported higher stress and showed significantly increased Pe amplitude versus controls.
• Higher perceived exam importance correlated positively with increased Pe amplitude.
• No significant effects of stress or exam importance were observed on Ne/ERN amplitude.

Conclusions:

• Long-term academic stress enhances the neural correlates of error evaluation.
• Increased Pe amplitude suggests a heightened motivational and emotional response to errors under stress.
• The findings highlight stress-induced alterations in cognitive control and error monitoring mechanisms.
