Abstract:

Categorical perception of colors is to recognize colors as groups despite tiny differences in shades. This is what we commonly experience in daily life. We have previously reported that the brain activity of 4-5 month-old infants showed differences in categorical responses between blue and green (Yang et al., 2016). This result suggests the possibility that pre-lingual infants hold categorical notions of colors in the brain. Greek has categorical differences between light and dark blue, and a previous study reported that EEG responses to blues were categorical, but not for greens, in Greek speakers (Thierry et al.,2009). We conducted a similar experiment with Japanese speakers, as they have similar categorical difference between light and dark blues (Kurikiet al., 2017). The result was not a simple replication of the Greek study; we seem to have found something different. I will report our results in detail.
