Error processing in young adulthood: Age-related differences in electrophysiology and behavioral performance

Area of Science:

• Cognitive Neuroscience
• Developmental Psychology
• Electrophysiology

Background:

• Error processing, including error-related negativity (ERN) and error positivity (Pe), develops through adolescence into adulthood.
• Immature error monitoring in early adulthood can hinder educational and professional goal attainment.
• Understanding age-related differences in error processing is crucial for this developmental stage.

Purpose of the Study:

• To investigate age-related variations in behavioral and neurocognitive error processing across young adulthood.
• To compare error processing between individuals in their early 20s, mid-20s, and early 30s.

Main Methods:

• Utilized electroencephalography (EEG) and a go/no-go task to assess error processing.
• Measured behavioral indexes: error rates, reaction times, and post-error slowing (PES).
• Analyzed event-related potentials: ERN and Pe amplitudes.
• Participants (N=95) were grouped into Early 20s (19-21), Mid 20s (23-26), and Early 30s (28-44).

Main Results:

• Young adults in their early 20s exhibited more impulsive errors and lacked post-error slowing (PES) compared to those in their early 30s.
• The early 30s group showed a larger ERN, indicating enhanced early stimulus control, and a smaller Pe amplitude, suggesting reduced later response evaluation.
• These findings suggest a more adult-like error processing pattern emerges by the early 30s.

Conclusions:

• Behavioral and neurocognitive response strategies for stable, adult-level performance may not be fully developed in the early 20s.
• Targeted interventions could enhance performance by introducing more efficient error monitoring and response strategies.
• This research highlights critical developmental changes in error processing during young adulthood.
