奖励处理通常被认为是一个整体结构，不同的激励类型会引发相同的神经和行为反应。大多数关于奖励处理的文献都使用金钱激励来引发与奖励相关的活动;然而，社会激励可能特别重要，因为它们具有塑造行为的强大能力。比较社会奖励和金钱奖励的研究发现，既有重叠的反应，也有不同的反应。为了探索奖励处理是领域通用的还是类别特定的（即，本研究记录了青少年（12-13岁）和初成人（18-25岁）完成社会和金钱奖励任务时的事件相关电位（ERP）。时空主成分分析显示，形态相似的奖励积极性（RewPs）在社会和货币奖励任务，在每个年龄组。在青少年早期，没有显着差异的大小之间的RewP社会和金钱奖励。然而，在新兴的成年人中，货币奖励的RewP显著大于社会奖励的RewP。此外，在两个年龄组中，对两项任务之间的反馈的反应没有显着相关性。这些结果表明，域一般和特定类别的过程的神经反应的奖励和不同类型的奖励的相对激励价值可能会改变整个发展。这项研究的结果对于理解奖励的神经反应在青春期精神病理学发展中的作用具有重要意义。
Reward processing is often considered to be a monolithic construct, with different incentive types eliciting equivalent neural and behavioural responses. The majority of the literature on reward processing has used monetary incentives to elicit reward-related activity; yet social incentives may be particularly important due to their powerful ability to shape behaviour. Findings from studies comparing social and monetary rewards have identified both overlapping and distinct responses. In order to explore whether reward processing is domain-general or category-specific (i.e., the same or different across reward types), the present study recorded event-related potentials (ERPs) from early adolescents (ages 12-13) and emerging adults (ages 18-25) while they completed social and monetary reward tasks. Temporospatial principal components analysis revealed morphologically-similar reward positivities (RewPs) in the social and monetary reward tasks in each age group. In early adolescents, no significant difference was found between the magnitude of the RewP to social and monetary rewards. In emerging adults, however, the RewP to monetary rewards was significantly larger than the RewP to social rewards. Additionally, responses to feedback between the two tasks were not significantly correlated in either age group. These results suggest that both domain-general and category-specific processes underlie neural responses to rewards and that the relative incentive value of different types of rewards may change across development. Findings from this study have important implications for understanding the role that neural response to rewards plays in the development of psychopathology during adolescence.
