Computer-based Attention Training in Patients With Acquired Brain Injury

"The N-back task required patients to monitor a continuous sequence of stimuli (in this experiment audio and visual stimuli). Press a button if the current stimulus is the same as that shown N back in the sequence. N increases if performance is good and decreases if performance is poor.~Subjects train for 20 days, 12 blocks a day, 20+N trials per block. That is 240 blocks in total. A minimum of 10 blocks per day counts as a successfully trained day."

"The Visual Search task consists of a NxN array of shapes. Press the button if a certain target stimulus is present in this array. N increases if performance is good and decreases if performance is poor.~Subjects train for 20 days, 12 blocks a day, 20+N trials per block. That is 240 blocks in total. A minimum of 10 blocks per day counts as a successfully trained day."
