Illustration of the N-back task, showing six trials of the 0-back level (left) and six trials of the 2-back level (right), together with the appropriate responses. At the 0-back level, subjects only have to push a button spatially corresponding to the location of a number on the screen. At the 2-back level, subjects must push a button spatially corresponding to a number that appeared two trials earlier.
