Decision-making is a conserved evolutionary process enabling us to choose one option among several alternatives, and relies on reward and cognitive control systems. The Iowa Gambling Task allows the assessment of human decision-making under uncertainty by presenting four card decks with various cost-benefit probabilities. Participants seek to maximise their monetary gain by developing long-term optimal-choice strategies. Animal versions have been adapted with nutritional rewards, but interspecies data comparisons are scarce. Our study directly compares the non-pathological decision-making performance between humans and wild-type C57BL/6 mice. Human participants completed an electronic Iowa Gambling Task version, while mice a maze-based adaptation with four arms baited in a probabilistic way. Our data shows closely matching performance between both species with similar patterns of choice behaviours. However, mice showed a faster learning rate than humans. Moreover, both populations were clustered into good, intermediate and poor decision-making categories with similar proportions. Remarkably, mice characterised as good decision-makers behaved the same as humans of the same category, but slight differences among species are evident for the other two subpopulations. Overall, our direct comparative study confirms the good face validity of the rodent gambling task. Extended behavioural characterisation and pathological animal models should help strengthen its construct validity and disentangle the determinants in animals and humans decision-making.

不确定性下的建模决策:人鼠赌博数据的直接比较研究

决策是一个保守的进化过程,使我们能够从多个备选方案中选择一个,并依赖于奖励和认知控制系统。爱荷华州赌博任务通过展示具有各种成本收益概率的四副牌来评估不确定性下的人类决策。参与者寻求通过制定长期最优选择策略来最大化他们的货币收益。动物版本已经适应了营养奖励,但种间数据比较很少。我们的研究直接比较了人类和野生型 C57BL/6 小鼠之间的非病理决策性能。人类参与者完成了一个电子爱荷华赌博任务版本,而老鼠则是基于迷宫的适应,四只手臂以概率方式诱饵。我们的数据显示,具有相似选择行为模式的两个物种之间的表现非常匹配。然而,老鼠表现出比人类更快的学习速度。此外,这两个群体以相似的比例被分为良好、中等和较差的决策类别。值得注意的是,被描述为良好决策者的小鼠的行为与同一类别的人类相同,但其他两个亚群的物种间略有差异。总体而言,我们的直接比较研究证实了啮齿动物赌博任务的良好表面效度。扩展的行为特征和病理动物模型应有助于加强其结构有效性并理清动物和人类决策中的决定因素。老鼠表现出比人类更快的学习速度。此外,这两个群体以相似的比例被分为良好、中等和较差的决策类别。值得注意的是,被描述为良好决策者的小鼠的行为与同一类别的人类相同,但其他两个亚群的物种间略有差异。总体而言,我们的直接比较研究证实了啮齿动物赌博任务的良好表面效度。扩展的行为特征和病理动物模型应有助于加强其结构有效性并理清动物和人类决策中的决定因素。老鼠表现出比人类更快的学习速度。此外,这两个群体以相似的比例被分为良好、中等和较差的决策类别。值得注意的是,被描述为良好决策者的小鼠的行为与同一类别的人类相同,但其他两个亚群的物种间略有差异。总体而言,我们的直接比较研究证实了啮齿动物赌博任务的良好表面效度。扩展的行为特征和病理动物模型应有助于加强其结构有效性并理清动物和人类决策中的决定因素。被描述为良好决策者的小鼠的行为与同一类别的人类相同,但其他两个亚群的物种间略有差异。总体而言,我们的直接比较研究证实了啮齿动物赌博任务的良好表面效度。扩展的行为特征和病理动物模型应有助于加强其结构有效性并理清动物和人类决策中的决定因素。被描述为良好决策者的小鼠的行为与同一类别的人类相同,但其他两个亚群的物种间略有差异。总体而言,我们的直接比较研究证实了啮齿动物赌博任务的良好表面效度。扩展的行为特征和病理动物模型应有助于加强其结构有效性并理清动物和人类决策中的决定因素。
