For those of you who enjoy visual games that play with perception and cognition, I invited you to have a go at The Color Test, a flash animation that demonstrates how challenging it can be to control your attention.
It is one of many versions available online of the Stroop Test, a task in which participants are presented with words for colors and must state the color the word is printed in but not the color the word names. Overriding one’s initial response — to read the word — proves difficult indeed.
