Intertemporal decision-making is the choice between an immediate smaller reward (SS) and a delayed larger reward (LL). Intertemporal decision-making depends on the interaction of the cognitive and emotional systems, and the latter is particularly vital. According to the Appraisal Tendency Frame (ATF) theory, anger influences intertemporal decision-making by increasing an individual's sense of certainty and control. This study examined whether anger affects intertemporal decision-making in individuals with internet addiction (IA) in this manner and investigated its neural mechanisms. Nineteen individuals with IA and 20 healthy controls were recruited. All subjects performed the Monetary choice task under anger and neutral emotions while functional near-infrared spectroscopy (fNIRS) equipment simultaneously recorded the hemodynamics in the prefrontal cortex (PFC). Individuals with IA showed a more considerable delay discount and lower brain activations in the orbitofrontal cortex (OFC) and left dorsolateral prefrontal cortex (L-dlPFC) compared to HC. Moreover, individuals with IA made more LL choices in the angry condition than in the neutral emotion, yet there was no difference in HC. The brain activation in L-dlPFC of individuals with IA tends to increase in the angry condition compared to the neutral condition. These findings revealed that impairment of intertemporal decision-making in individuals with individuals with IA might be related to the dysfunction of OFC and L-dlPFC. Our work also provided initial footing for the applicability of the appraisal tendency frame theory to individuals with IA, and L-dlPFC might play a role in the effects of anger on intertemporal decision-making.
跨期决策是在即时较小奖励（SS）和延迟较大奖励（LL）之间进行选择。跨期决策取决于认知系统和情感系统的相互作用，其中情感系统尤为重要。根据评价倾向框架（ATF）理论，愤怒通过增强个体的确定感和控制感来影响跨期决策。本研究考察了愤怒是否以这种方式影响网络成瘾（IA）个体的跨期决策，并探究其神经机制。招募了19名IA个体和20名健康对照者。所有受试者在愤怒和中性情绪下执行货币选择任务，同时功能近红外光谱（fNIRS）设备记录前额叶皮层（PFC）的血流动力学。与健康对照者相比，IA个体表现出更大的延迟折扣，眶额皮层（OFC）和左侧背外侧前额叶皮层（L-dlPFC）的脑激活较低。此外，IA个体在愤怒状态下比在中性情绪下做出更多的LL选择，但健康对照者没有差异。与中性状态相比，IA个体在愤怒状态下L-dlPFC的脑激活趋于增加。这些发现表明，IA个体跨期决策的受损可能与OFC和L-dlPFC的功能障碍有关。我们的研究还为评价倾向框架理论在IA个体中的适用性提供了初步依据，并且L-dlPFC可能在愤怒对跨期决策的影响中起作用。
