习得的语言范畴影响颜色知觉的机制:来自ERP的证据

The Effects of Trained Lexical Categories on Color Perception:Evidences from ERPs

本研究以两个实验探讨了习得的语言范畴影响颜色知觉的机制。实验1让被试接受短期"色-词"重组训练,使原先范畴内的两种颜色变为范畴间的颜色,训练前后完成视觉搜索任务。反应时结果显示,在训练后,与训练的两种颜色近似的另外两种颜色的知觉表现出边缘显著的偏侧化颜色范畴效应。实验2让被试接受与实验1相同的训练后,完成视觉Oddball任务。ERP结果显示,在训练后,与训练的两种颜色近似的另外两种颜色的偏差刺激在早期知觉阶段就表现出偏侧化v MMN效应。这些结果表明:习得的语言范畴能影响早期的、注意前的颜色知觉机能,且这一影响过程可以在短期内完成;习得的语言范畴会影响颜色知觉范畴,而非仅影响特定颜色点的知觉机能。

The current research investigated how lexical categories affected color perception. In Experiment 1,participants received a short-term color name and color re-organization training,which aimed to change two withincategory colors into between-category colors,and then finished a visual search task. Results showed that,after training,participants distinguished two colors similar to the trained colors faster in the right visual field than in the left visual field. In Experiment 2,participants received the same training as Experiment 1,and then completed a visual Oddball task. Results showed that the deviants similar to the trained colors evoked larger v MMN effects in the right visual field than in the left visual field. These findings suggested that the trained lexical categories distort or warp color perception in a short time. In addition,the trained lexical categories distort or warp the perception of a color category rather than a certain color exemplar.
