研究表明，东亚人和欧洲美国人在社会和认知过程中存在差异。东亚人被认为对情境背景更敏感，更关注感知领域，而欧洲裔美国人则被认为更关注对象，更独立于领域。本实验的目的是研究神经反应的差异，以目标对象和刺激背景之间的东亚裔美国人和欧洲裔美国人使用三刺激新奇P3事件相关电位设计。正如假设的那样，欧裔美国人表现出相对更大的目标P3振幅，表明对目标事件的注意力，而东亚裔美国人表现出相对更大的新奇P3振幅，表明对上下文异常事件的注意力。此外，作者还发现，相互依存的自我联想在文化与新奇性P3之间起中介作用。这些发现确定了一种特定的神经活动模式，与背景敏感性的既定文化差异有关。
Research has demonstrated differences in social and cognitive processes between East Asians and European Americans. Whereas East Asians have been characterized as being more sensitive to situational context and attending more to the perceptual field, European Americans have been characterized as being more focused on the object and being more field independent. The goal of the present experiment was to investigate differences in neural responses to target objects and stimulus context between East Asian Americans and European Americans using a three-stimulus novelty P3 event-related potential design. As hypothesized, European Americans displayed relatively greater target P3 amplitudes, indexing attention to target events, whereas East Asian Americans displayed relatively greater novelty P3 amplitudes, indexing attention to contextually deviant events. Furthermore, the authors found that interdependent self-construal mediated the relationship between culture and the novelty P3. These findings identify a specific pattern of neural activity associated with established cultural differences in contextual sensitivity.
