Purpose:
Hearing impairment adversely affects the development and maturation of the ventrolateral prefrontal cortex, which is a region critical for social emotion regulation. The present study aimed to examine how hearing impairment influences socially-based emotion regulation in adolescents or its underlying neural mechanisms.
Method:
To address this gap, the present study recorded event-related potentials (ERP) while participants viewed images depicting social exclusion or used emotion regulation strategies to down-regulate their emotional responses.
Finding:
Behavioral results indicated that normal-hearing adolescents reported a significant reduction in negative affect when employing regulation strategies, an effect not observed in hearing-impaired adolescents. ERP data indicated that compared to passive viewing, expressive suppression elicited reduced amplitudes in the central-parietal LPP and P3 components among normal-hearing adolescents. This modulation was attenuated in those with hearing impairment.
Conclusion:
These results suggest that deficits in both attention allocation and elaborative emotional processing may underlie the impaired down-regulation of socially triggered negative emotions in adolescents with hearing loss.
