The auditory system’s responsiveness (as indexed by auditory brainstem responses) to a sound in four conditions: one wherein the participants actively listened to the sound and three wherein the participants conducted the n-back task (3-back = high difficulty, 1-back = low difficulty). Error bars show standard errors of the means.
