Damasio proposes in his somatic marker theory that not only cognitive but also affective components are critical for decision making. Since affective judgment requires an interplay between affective and cognitive components, it might be considered a key process in decision making that has been linked to neural activity in ventromedial prefrontal cortex (VMPFC). Using functional magnetic resonance imaging (fMRI), we examined the relationship between VMPFC, emotionally (unexpected)- and cognitively (expected)-accentuated affective judgment, and beneficial decision making (Iowa Gambling Task; IGT) in healthy subjects. Neuronal activity in the VMPFC during unexpected affective judgment significantly correlated with both global and final performance in the IGT task. These findings suggest that the degree to which subjects recruit the VMPFC during affective judgment is related to beneficial performance in decision making in gambling.
达马西奥在其躯体标记理论中提出,不仅认知成分,情感成分对决策也至关重要。由于情感判断需要情感和认知成分之间的相互作用,它可能被视为决策中的一个关键过程,这一过程已与腹内侧前额叶皮层(VMPFC)的神经活动相关联。我们使用功能磁共振成像(fMRI),研究了健康受试者中VMPFC、情感(意外)和认知(预期)强化的情感判断以及有益决策(爱荷华赌博任务;IGT)之间的关系。在意外情感判断期间,VMPFC中的神经元活动与IGT任务中的整体表现和最终表现均显著相关。这些发现表明,受试者在情感判断期间调动VMPFC的程度与赌博决策中的有益表现相关。
