行为研究表明，西方人更关注物体，而东亚人更关注关系和背景。我们在一项与事件相关的fMRI研究中评估了这些文化差异的神经基础。东亚和美国的参与者偶然编码了以下图片：（1）单独的目标对象，（2）没有可识别目标对象的背景场景，以及（3）在有意义的背景下的独特目标对象。与东亚人相比，美国人激活了更多涉及对象加工的区域，包括双侧颞中回、左侧上级顶/角回和右侧上级颞/缘上回。与客体加工区域的文化差异相比，背景加工区域的差异较小。这些结果表明，文化经验微妙地直接神经活动，特别是焦点对象，在场景编码的早期阶段。
Behavioral research suggests that Westerners focus more on objects, whereas East Asians attend more to relationships and contexts. We evaluated the neural basis for these cultural differences in an event-related fMRI study. East Asian and American participants incidentally encoded pictures of (1) a target object alone, (2) a background scene with no discernable target object, and (3) a distinct target object against a meaningful background. Americans, relative to East Asians, activated more regions implicated in object processing, including bilateral middle temporal gyrus, left superior parietal/angular gyrus, and right superior temporal/supramarginal gyrus. In contrast to the cultural differences in object-processing areas, few differences emerged in background-processing regions. These results suggest that cultural experiences subtly direct neural activity, particularly for focal objects, at an early stage of scene encoding.
