Showed students clay creatures with prominent heads, pointy limbs, students identified which were friendly or not; unfriendly had lumpy heads friendly had smooth; Usually language enhances thinking but can also screw us up. Study: russian and english speakers look at three blocks of color and say which two are the same; russian has different words for dark and light blue, english only has blue. Hypothesis: language is dominant on left side of brain then it should affect color perception in right visual field. If shown 2 dark and 1 light russian speakers responded faster than 3 dark or 3 light. English speakers responded same no matter the mix of shades. Another condition: made subjects do a task while color-matching.
