Scholars are now interested in whether having a vocabulary item for a concept influences thought in domains far from language, such as visual perception. Consider the case of the "Russian blues." While English has a single word for blue, Russian has two words, goluboy for light blue and siniy for dark blue. These are considered "basic level" terms, like green and purple, since no adjective is needed to distinguish them. Lera Boroditsky and her colleagues displayed two shades of blue on a computer screen and asked Russian speakers to determine, as quickly as possible, whether the two blue colors were different from each other or the same as each other. The fastest discriminations were when the displayed colors were goluboy and siniy, rather than two shades of goluboy or two shades of siniy. The reaction time advantage for lexically distinct blue colors was strongest when the blue hues were perceptually similar.

What arenas of perceptual-linguistic interaction remain to be conquered? The current finding indicates that linguistic knowledge can influence perception, contradicting the traditional view that perception is processed independently from other aspects of cognition, including language. This is most famously seen in the case of visual illusions, which are mostly impervious to knowledge about the illusion. Hmm. One wonders: Could the Russian Blues be recruited in altering a visual illusion that depends on color shades?
