Eriksen flanker task

The Eriksen flanker task is a psychology paradigm. In a visual experiment the reagent is expected to respond to a centered and directed item surrounded or flanked by distracting symbols like arrows or letters. They are called congruent if they all point to the same direction, the subject will have a short reaction time and performance is more exact. Flanking arrows that point to a different direction are therefore incongruent and correspond to a slower reaction time and less accurate performance.
