以彝族、白族、纳西族和汉族的大学生为被试，采用颜色相似性判断和颜色再认任务，考察了彝族、白族、纳西族和汉族的大学生对于黑色和白色的认知，意在探究不同民族的黑、白文化是否影响人们对黑、白颜色的认知。结果发现：⑴彝族、白族、纳西族和汉族的黑、白文化影响四个民族的大学生对于黑色和白色的认知；⑵语言和文化对于颜色认知的影响包括间接效应和直接效应。整个研究表明，语言和文化对颜色认知有重要影响

Cuiture's Effects on' black' and' white' Color Cognition of Undergraduates from Yi Nation, Bai Nation, Naxi Nation and Han Nation

Color cognition is a key issue on the debates of Linguistic Universalism and Relativity. Universalists declare that color cognition is independent with language and culture, is human’s common cognition ability, and will not be affected by language and culture. Whereas, Relativitists state that color cognition is affected by language and culture. Relativitists put forward four aspects of evidence to oppose Universalism, that is, data analyzing, ‘blue’ and ‘green’ cognition, cross-species researches and neuropsychological founding. However, Universalists doubted that whether the effects of language and culture on color cognition are direct or indirect. That is, does language and culture change color cognition perceptually or just assist people to finish tasks as an online strategy? This study was probe into the relationship between ‘black’/‘white’ cultures and ‘black’/‘white’ color cognition to investigate whether the different ‘black’/‘white’ cultures of Yi nation, Bai nation, Naxi nation and Han nation would influence the ‘black’/‘white’ color discrimination of people from these four nations, and to explore whether these language and culture effects are direct or indirect. There were two experiments in this study. Eighty-eight participants of Yi, Bai, Naxi and Han Nations from Yunnan Dali Institute took part in the experiments. Participants were asked to finish color similarity judgment in experiment 1 and finish color recognition task in experiment 2. Materials were selected according to CIE1976 L*a*b* and consisted of 7 ‘black’ and 7 ‘white’ stimulus which were all the same on wavelength and saturation (a* = b* = 0) but different on lightness. In experiment 1, there were three colors presented at the same time on the screen in every trial. Subjects were asked to judge which color was more similar with the color presented on the center of the screen, the color on the left side or right side. In experiment 2, subjects were asked to memorize the target color, and to recognize it 30s later by choosing it from two colors. All data were analyzed by SPSS10.0. The results of experiment 1 showed that undergraduates from Yi Nation discriminated black stimulus with different lightness significantly faster and more accurate than discriminated the white ones, while subjects from Bai Nation distinguished white colors with different lightness notably faster and more accurate than distinguished the black ones. Participants from Naxi Nation had no significant difference when they discriminated different lightness ‘black’ and ‘white’. Neither did students from Han Nation. The results in experiment 2 found the same tendency with experiment 1 except that the difference between ‘black’ and ‘white’ discrimination in every nation enlarged on both reaction time and error ratio. The whole study showed that ⑴ the culture differences on ‘black’ and ‘white’ of Yi, Bai, Naxi and Han Nation affected the color ‘black’ and ‘white’ discrimination of undergraduates from these four nations; ⑵ the effects of language and culture on color cognition include indirect effect and direct effect
