The Stroop Effect: Automatic Reading Interferes with Colour Naming
In the Stroop task participants name the ink colour of colour words while ignoring what the word says. Incongruent trials, where the word and ink colour disagree, are slower and more error-prone than congruent or neutral trials. The interference shows that skilled reading is automatic and hard to suppress, and the size of the effect is used as an index of selective attention and executive control.
