Age and Social Observation Effects on Theta Synchrony and Its Role in Adolescent Post-Error Control: A Computational...

Area of Science:

• Neuroscience
• Cognitive Neuroscience
• Developmental Neuroscience

Background:

• Error monitoring, crucial for behavioral adaptation, involves midfrontal theta EEG activity.
• Post-error adaptations are linked to theta synchrony between midfrontal and lateral brain regions.
• Limited research exists on age-related changes in error-related theta synchrony during adolescence and social observation effects.

Purpose of the Study:

• To investigate age-related changes in error-related theta synchrony dynamics across adolescence.
• To examine the influence of social observation on these neural dynamics.
• To link specific theta synchrony patterns to post-error behavioral adjustments using computational modeling.

Main Methods:

• Utilized behavioral and electroencephalography (EEG) data from 262 adolescents (aged 10-14 years).
• Participants completed a flanker task both alone and while observed by a peer.
• Employed the shrinking spotlight drift diffusion model (SSP-DDM) for computational analysis.

Main Results:

• Found age-related increases in error-related midfrontal-frontolateral and midfrontal-midlateral theta synchrony, irrespective of social observation.
• Error-related midfrontal-posterolateral theta synchrony increased only when participants performed the task alone.
• A positive association was identified between midfrontal-posterolateral theta synchrony and post-error attentional control, with no social observation effect.

Conclusions:

• Demonstrated that error-related theta synchrony increases from early to mid-adolescence.
• Established a specific link between midfrontal-posterolateral theta synchrony and enhanced post-error attentional control.
• Highlighted the developmental trajectory of neural mechanisms underlying error processing and adaptation in adolescents.
