Interdependent self-construal (SC) is thought to lead to a more holistic cognitive style that emphasizes the processing of the background scene of a focal object. At present, little is known about whether the structural properties of the brain might underlie this functional relationship. Here, we examined the gray matter (GM) volume of three cortical regions involved in scene processing -- a cornerstone of contextual processing. Study 1 tested 78 European American non-student adults and found that interdependent (vs. independent) SC predicts higher GM volume in the parahippocampal place area (PPA), one of the three target regions. Testing both European American and East Asian college students (total N = 126), Study 2 replicated this association. Moreover, the GM volume of all the three target regions was greater for East Asians than for European Americans. Our findings suggest that there is a structural neural underpinning for the cultural variation in cognitive style.
相互依存的自我构念(SC)被认为会导致更具整体性的认知风格,强调焦点物体背景场景的处理。目前,人们对大脑的结构特性是否会成为这种功能关系的基础知之甚少。在这里,我们研究了三个与场景处理相关的皮质区域的灰质(GM)体积,这是上下文处理的基石。研究 1 测试了 78 名欧洲裔美国非在校成年人,发现相互依存(相对于独立)的 SC 预测了三个目标区域之一的旁海马位置区域(PPA)的 GM 体积更高。通过对欧洲裔美国人和东亚大学生(总 N=126)进行测试,研究 2 复制了这种关联。此外,所有三个目标区域的 GM 体积在东亚人身上都大于欧洲裔美国人。我们的发现表明,认知风格的文化差异存在结构神经基础。
