摘要

时际决策是指在即时的较小奖励(SS)和延迟的较大奖励(LL)之间做出选择。时际决策取决于认知系统和情绪系统的相互作用,而后者尤为重要。根据评估倾向框架(ATF)理论,愤怒会通过增强个体的确定感和控制感来影响跨时空决策。本研究探讨了愤怒是否会以这种方式影响网络成瘾(IA)患者的跨时空决策,并研究了其神经机制。研究人员招募了 19 名网瘾患者和 20 名健康对照者。所有受试者都在愤怒和中性情绪下进行了专有选择任务,同时功能性近红外光谱(fNIRS)设备记录了前额叶皮层(PFC)的血流动力学。与HC相比,IA患者的延迟折扣更大,眶额皮层(OFC)和左侧背外侧前额皮层(L-dlPFC)的脑激活更低。此外,与中性情绪相比,IA患者在愤怒状态下做出的LL选择更多,但在HC中却没有差异。与中性情绪相比,内分泌失调患者在愤怒状态下左侧大脑皮层的大脑激活程度趋于增加。这些研究结果表明,内分泌失调患者的时际决策障碍可能与OFC和L-dlPFC的功能障碍有关。我们的研究还为评估倾向框架理论在内分泌失调患者中的适用性提供了初步依据,而L-dlPFC可能在愤怒对跨时决策的影响中扮演了一定的角色。

The impact of anger on intertemporal decision-making in individuals with internet addiction: an fNIRS study.

The impact of anger on intertemporal decision-making in individuals with internet addiction: an fNIRS study.

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.

期刊介绍: The original papers published in the European Archives of Psychiatry and Clinical Neuroscience deal with all aspects of psychiatry and related clinical neuroscience. Clinical psychiatry, psychopathology, epidemiology as well as brain imaging, neuropathological, neurophysiological, neurochemical and moleculargenetic studies of psychiatric disorders are among the topics covered. Thus both the clinician and the neuroscientist are provided with a handy source of information on important scientific developments.
