ABSTRACT The current study examines associations between neural activation to the receipt of monetary reward in a rewarding game task and bias toward immediate reward measured in a behavioral delay discounting task among early adolescents (N = 58, 12–14 years). As expected, heightened brain activation in reward-related regions were correlated with higher bias toward immediate reward. This suggests that bias toward immediate reward in delay discounting tasks may be linked to heightened activation to reward in reward processing regions. This interplay between neural reward processing and bias toward immediate reward might explain the sharp increases in bias toward immediate reward that occur in early adolescence.

青少年大脑对奖励的反应与对即时奖励的偏见有关

摘要 目前的研究检查了神经激活与在奖励游戏任务中获得金钱奖励之间的关联，以及在早期青少年（N = 58、12-14 岁）的行为延迟折扣任务中测量的对即时奖励的偏见。正如预期的那样，奖励相关区域的大脑活动增强与对即时奖励的更高偏见相关。这表明延迟折扣任务中对即时奖励的偏见可能与奖励处理区域中奖励的激活程度提高有关。神经奖励处理和对即时奖励的偏见之间的这种相互作用可能解释了青春期早期对即时奖励的偏见急剧增加。
