Insights
Younger children show greater conflict susceptibility, with distinct neural responses to errors compared to adults. This suggests developing cognitive control involves separate timelines for conflict monitoring and error processing.
Area of Science:
- Neuroscience
- Developmental Psychology
- Cognitive Science
Background:
- Cognitive control undergoes significant development throughout childhood and adolescence.
- Understanding age-related neural mechanisms of cognitive control is crucial for developmental research.
Purpose of the Study:
- To investigate age-related changes in cognitive control using event-related potentials (ERPs).
- To examine neural responses to conflict monitoring and error processing across different age groups.
Main Methods:
- Recorded ERPs in children (6-9 years, 10-12 years) and young adults during a Flanker task.
- Analyzed N2 component for conflict monitoring and error-related negativity (ERN) for error processing.
Main Results:
- Younger children exhibited higher susceptibility to conflict compared to older children and adults.
- N2 amplitude was smaller in younger children versus older children and adults.
- ERN amplitude was larger in adults than in children, with no difference between child groups.
Conclusions:
- Neural responses to error processing mature later than those for conflict monitoring.
- Dissociable developmental timelines for subdivisions of the anterior cingulate cortex may underlie these findings.
Abstract:
To study age-related changes in cognitive control, event-related potentials (ERPs) of children aged 6-9 years, 10-12 years, and young adults were recorded during a Flanker task. Younger children were more susceptible to conflict than older ones and adults. The N2 in incongruent trials was smaller in younger than older children, who did not differ from adults. The error-related negativity (ERN) following errors, however, was larger in adults than in children, but did not differ between younger and older children. Delayed development of neural responses to error processing relative to conflict monitoring may indicate dissociable maturational time tables of subdivisions of the anterior cingulate cortex.
