Our Language Affects What We See
A highly salient stimulus was a green (either light or dark green) triangle against a blue (either light or dark blue) background, because the colors were in different linguistic categories. A stimulus which would also be highly salient for Russian speakers was a light or dark blue triangle positioned against a circle with the differing blue color. This neural signature was not present for the light green / dark green stimulus, indicating that the brain processes the light blue / dark blue differently, for speakers whose language makes a lexical distinction.
