Abstract

In many situations, decision-making behaviors are mostly composed of team patterns (i.e., more than two persons). However, brain-based models that inform how team interactions contribute and impact team collaborative decision-making (TCDM) behavior, is lacking. To examine the neural substrates activated during TCDM in realistic, interpersonal interaction contexts, dyads were asked to model TCDM toward their opponent, in a multi-person prisoner's dilemma game, while neural activity was measured using functional near infrared spectroscopy. These experiments resulted in two main findings. First, there are different neural substrates between TCDM and ISDM, which were modulated by social environmental cues. i.e., the low incentive reward yielded higher activation within the left inferior frontal gyrus (IFG), in individual separately decision-making (ISDM) stage while the dorsolateral prefrontal cortex (DLPFC) and the middle frontopolar area was activated in TCDM stage. The high incentive reward evoked a higher interbrain synchrony (IBS) value in the right IFG in TCDM stage. Second, males showed higher activation in the DLPFC and the middle frontopolar area during ISDM, while females evoked higher IBS in the right IFG during TCDM. These sex effects suggest that in individual social dilemma situations, males and females may separately depend on non-social and social cognitive ability to make decisions, while in the social interaction situations of TCDM, females may depend on both social and non-social cognitive abilities. This study provide a compelling basis and interesting perspective for future neuroscience work of TCDM behaviors.Copyright © 2021 Zhang, Jia and Wang.

在很多情况下,决策行为大多由团队模式(即两个以上的人)组成。然而,缺乏基于大脑的模型来告知团队互动如何促进和影响团队协作决策 (TCDM) 行为。为了在现实的人际互动环境中检查 TCDM 期间激活的神经底物,在多人囚徒困境游戏中,要求二人对对手建立 TCDM 模型,同时使用功能性近红外光谱测量神经活动。这些实验导致了两个主要发现。首先,TCDM 和 ISDM 之间存在不同的神经基质,它们受社会环境线索的调节。即,在个体独立决策 (ISDM) 阶段,低激励奖励在左额下回 (IFG) 内产生更高的激活,而背外侧前额叶皮层 (DLPFC) 和中额极区在 TCDM 阶段被激活。高激励奖励在 TCDM 阶段在正确的 IFG 中引起了更高的脑间同步 (IBS) 值。其次,在 ISDM 期间,男性在 DLPFC 和中间额极区显示出更高的激活,而女性在 TCDM 期间在右侧 IFG 中引起更高的 IBS。这些性别效应表明,在个体社会困境情境中,男性和女性可能分别依赖于非社会和社会认知能力做出决定,而在 TCDM 的社会互动情境中,女性可能同时依赖于社会和非社会认知能力。 .这项研究为未来 TCDM 行为的神经科学工作提供了令人信服的基础和有趣的视角。 版权所有 © 2021 Zhang, Jia 和 Wang。
