The Study Of Neurophysiological Underpinnings Of Monetary And Social Incentive Processing In Adolescents: ERP Study

Rewards are of great significance to individuals,and individual behavior is driven by prospects of reward.Rewards can be described as positive outcomes or events from which individuals can benefit subjectively or objectively.One can,furthermore,distinguish between primary and secondary rewards.Primary rewards include those that are necessary for survival of the species,such as food and water.Secondary rewards derive their beneficial value from primary rewards and include,for instance,monetary gains.The aim of this event-related potential(ERP)study is to compare the neurophysiological underpinnings of monetary and social incentive processing in adolescents.Furthermore,Whether this difference is also significant in developmental research.Based on this,this study consists of two experiments:In study 1,the aim of this event-related potential(ERP)study was to compare the neurophysiological underpinnings of monetary and social incentive processing in adolescents.During ERP recording,40 adolescents completed an incentive delay task comprising(a)a reward versus punishment condition and(b)social versus monetary incentives.The results show that:(1)Adolescents exhibited higher FRN and P3 amplitudes to social incentives compared with monetary incentives,(2)In the early stage of processing,the amplitude of FRN induced by social punishment is the highest.(3)In the late stage of processing,the P3 amplitude induced by social reward was the highest.In study,the aim of this event-related potential(ERP)study was to compare the neurophysiological underpinnings of monetary and social incentive processing in adolescents versus adult.During ERP recording,31 adolescents and 30 adult completed an incentive delay task comprising(a)a reward versus punishment condition and(b)social versus monetary incentives.The results show that:(1)Adolescents exhibited higher FRN and P3 amplitudes to social incentives compared with adults.(2)In the early stage of processing,Adolescents exhibited higher FRN amplitudes to social reward and social punishment compared with adults.(3)In the late stage of processing,adolescents exhibited higher P3 amplitudes to socialreward compared with adults.The above research results suggest that adolescents may have a dominant position in neurophysiological underpinnings social incentive compare with monetary incentive.And,this view has also been verified in development research.In the early stage,adolescents’ attention bias to social punishment may be related to their vigilance to social negative feedback;in the late stage,adolescents’ attention resources focus on social reward,which shows that social reward has more significance and value for adolescents.This study is a supplement to the study of neural processing differences in incentive types in adolescents.This study also provides a neurophysiological basis for the debate on the age difference of incentive type processing between adolescents and adults.At the same time,the research results can provide reference for guiding the development of teenagers and adjusting their behaviors.
