不同熟练度双语者的颜色范畴知觉效应：来自行为和ERP的证据

为研究语言对知觉的影响作用, 行为实验采用视觉搜索范式研究蒙汉双语者的颜色范畴知觉效应; 为进一步考察语言影响知觉的脑机制, 脑电实验采用Oddball范式研究蒙汉双语者的颜色范畴知觉效应。行为实验和脑电研究结果都发现, 在区分蒙古语中qinker和huhe色时, 低汉语水平的蒙汉双语者比高汉语水平者产生更强的颜色范畴效应, 蒙汉双语者的汉语水平影响颜色范畴知觉, 双语者所习得的第二语言范畴可以改变双语者母语的范畴, 语言能影响知觉的前注意阶段, 本研究支持了Spair-Whorf假设。

Behavioral and ERP study of color categorical perception in proficient and nonproficient bilinguals

Color categorical perception (CCP: faster or more accurate discrimination of color that straddles a color category boundary) has provided an empirical standard passage of the debate on the relation of language and cognition during the last half-century. A majority of studies suggested that CCP is tightly linked to the language and culture we are born into, which agreed with the Whorf hypothesis in which CCP is language-related and not universal. The participants of previous studies were mainly monolingual, so whether the results of monolingual research can be generalized to bilinguals remains uncertain. There are many Mongolian-Chinese bilinguals in Inner Mongolia. Mongolians divide the blue region of color space into a darker shade called huhe and a lighter shade called qinker, while both lighter blue and darker blue are simply described with the single word Lan in Chinese. To confirm whether the color category in first language (L1) of Mongolian-Chinese bilinguals is influenced by second language, the present study used a behavioral experiment and event-related potential (ERP) to compare the CCP between proficient bilinguals and nonproficient bilinguals.
