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.
