Development of emotion processing and regulation: Insights from event-related potentials and implications for internalizing disorders

Abstract

Emotionally-salient stimuli receive selective attention and elicit complex neural responses that evolve considerably across development. Event-related potentials (ERPs) optimally capture the dynamics of emotion processing and regulation, with sensitivity to detect changes in magnitude, latency, and maximal location across development. In this selective qualitative review, we summarize evidence of developmental changes in neural reactivity to emotional stimuli and modulation of neural responses during emotion regulation indexed by ERPs across infancy, childhood, and adolescence. The cumulative ERP literature suggests the transition from childhood to adulthood is characterized by a gradual decrease in neural reactivity to emotional stimuli and increased efficiency in attentional allocation towards emotional stimuli. Some studies show sensitivity to emotional stimuli peaks in adolescence, but the evidence is mixed. While both early (<300 ms) and late (>300 ms) ERPs demonstrate sensitivity to emotional stimuli, emotional modulation is more consistently observed in relatively later ERPs across development. The literature additionally shows improvements in regulation abilities across development, though ERP research on developmental changes in emotion regulation is still relatively limited, highlighting a critical direction for future research. Finally, we briefly discuss changes in emotion-related ERPs relevant to the emergence of depression and anxiety. Findings from this review indicate that ERPs provide abundant information about the development of emotion processing and regulation, with potential clinical utility for detecting early-emerging vulnerabilities for internalizing forms of psychopathology.
