Abstract

Most research on cultural neuroscience focuses on one dimension of culture: group membership or individual orientation. However, it is especially important to examine the intersection between the two to better understand the acculturation process. To examine the role of culture in the neural correlates of risky exploration, the current study recruited 22 American and 24 Chinese international students. Participants reported on their independent self-construal, a measure defining the self in terms of emphasizing unique attributes, and underwent an functional magnetic resonance imaging (fMRI) scan while completing a risk-taking task. At the group level, American (vs. Chinese) participants showed greater risky exploration on the task. Moreover, while independent self-construal was not related to American individuals' behavioral performance and neural correlates of risky exploration, Chinese participants who reported greater independent self-construal recruited greater activation in regions of the cognitive control system [e.g., dorsolateral prefrontal cortex (DLPFC)] and affective system [e.g., anterior insula (AI)], which was related to greater risky exploration. Taken together, our findings suggest that culture as group membership and individual orientation may interact with each other and relate to neural systems underlying risky exploration. This study highlights the importance of studying the role of culture at both group and individual level, which is particularly critical to understand individuals as they acculturate to a new environment.

摘要

大多数关于文化神经科学的研究都集中在文化的一个维度上

群体成员身份或个体取向。然而,研究二者之间的交叉点对于更好地理解文化适应过程尤为重要。为了研究文化在风险探索的神经关联中的作用,本研究招募了22名美国国际学生和24名中国国际学生。参与者报告了他们的独立自我建构,这是一种通过强调独特属性来定义自我的测量方法,并在完成一项冒险任务时接受了功能磁共振成像(fMRI)扫描。在群体层面,美国(与中国)参与者在任务中表现出更大的风险探索。此外,虽然独立自我建构与美国个体的行为表现和风险探索的神经关联无关,但报告有更高独立自我建构的中国参与者在认知控制系统区域[例如,背外侧前额叶皮层(DLPFC)]和情感系统区域[例如,前岛叶(AI)]中募集到了更强的激活,这与更大的风险探索有关。综上所述,我们的研究结果表明,作为群体成员身份和个体取向的文化可能会相互作用,并与风险探索背后的神经系统相关。这项研究强调了在群体和个体层面研究文化作用的重要性,这对于理解个体在适应新环境时的情况尤为关键。
