| 摘 要： | 奖赏对于人类的存在和发展具有很重要的意义,对奖赏加工过程的研究有助于我们从不同的视角诠释青少年风险行为形成的原因.通过线索数字的变化分析被试对奖赏结果的预期程度,研究青少年奖赏加工过程的预期阶段与结果体验阶段的认知和神经电生理过程,结果表明:青少年在面对不同预期线索刺激时,他们的唤醒度和动机水平都较高,对结果预期反应的准备活动也较强,并且,在结果评估的反馈负波上,青少年与成人均未表现出显著性差异,而对结果信息刺激,青少年表现出较高的情绪体验,同时也说明青少年认知调控能力还未发展成熟.

| Abstract: | Reward is very important for human existence and development,and the research of reward processing will help us interpret the reason of teenagers' risk-seeking from a unique perspective.Manipulating the reward probability of the subjects,the present study investigates the cognitive and neural electrophysiological processes in young adolescents in the anticipation and outcome phases of reward processing.The resulting electroencephalography shows that adolescents display a relatively high motivation level and... |
