YELLOW RED BLUE GREEN GREEN RED BLACK YELLOW GREEN WHITE BLACK YELLOW GREEN YELLOW BLUE YELLOW BLUE BLUE RED GREEN BLUE RED GREEN YELLOW BLUE RED GREEN YELLOW RED GREEN YELLOW BLUE GREEN YELLOW
Not as easy as one would think. It’s the Stroop Effect.
But what does this really tell us about perception or cognition?
How does this effect how we read ‘news’?
