Effect Of Color Naming On Color Perception

Cognitive processes include primary processing such as sensory and perception,and advanced processing such as memory,language,and thinking.There are two opposing views on whether advanced cognition can affect perception: Cognitive impenetrability view holds that the perception process is not regulated by advanced cognition,whereas the cognitive penetrability holds that there is a top-down regulation of advanced cognition for primary processing.A large number of studies have shown that language and another advanced cognition have a top-down modulation on visual perception.However,skeptics consider it not a regulation on pour perception,but rather confusing memory,recognition,decision-making,response bias or other factors.Therefore,the present study mainly focuses on the relationship between language label and visual perception.The early influence on perception of color term is discussed from the aspects of color nomenclature and categorical perception(CP)of color.In Experiment 1,using the event-related potential measurement,we aim to explore whether there is a difference in the perception process between the easy-to-name(EN)and the hard-to-name(HN)colors which is task-independent dimension,and whether the difference is affected by the verbal or visual interference task.The results show that compared with HN,EN elicit a more negative N170 on the left occipital region,But the difference is eliminated in the verbal interference task instead of the visual interference task.The results show that the language labels have real-time online regulation of perception.In Experiment 2,the continuous flashing suppression(CFS)paradigm combined with visual search paradigm is used to explore whether there is a unilateral effect of color categorical perception(CP)under subliminal perceptual condition.The CFS detection task is followed by the normal detection task.The both task show the right-visual-field lateralization effect of CP.The results show that language has an effect on perception,and the relationship between categories in the right visual field is more likely to break through inhibition.In order to further verify the reliability of the results,in Experiment 3,we carry out a cross-cultural research of Chinese and Korean and replace the color materials which for the Korean are two types of colors but one category for the Chinese.The tasks were same as Experiment 2.And the results are similar as Experiment 2,indiacted that both in the normal and CFS visual detection task,the lateralization effect of CP occurred.In summary,the results of the 3 experiments indicate that in the absence of interference factors such as recognition,language labels play a role in regulating color perception which support the cognitive penetrable perspectives.
