The CogniFit's Eriksen's Flanker Test is a digitized replica of the task of the same name (Eriksen and Eriksen, 1974). This task seeks to measure how much interference is generated by the presentation of adjacent incongruent and irrelevant visual information. The difference in reaction time between incongruent and congruent trials responded to correctly is what is known as the Flankers Effect.
