Attention to auditory fMRI stimuli is maintained by a deviant-counting task

Evidence

Stimuli of each of the eleven conditions plus a silence condition, which served as baseline, were presented 36 times over the course of the experiment. For the purpose of maintaining the participants’ attention towards the acoustic stimuli, they were asked to count the number of occasionally presented deviants, characterized by a transient dip in sound level in one of the noise bursts. — Dijk, Pim van, Physiology, Psychoacoustics and…, 2620
