An illustration of a segment of the 2.5-min tone sequence. Gray boxes are “standards” that conform to the pattern. Type A and type B tones have fundamental frequencies of 740 and 1,046.5 Hz, respectively. The open box is a repetition deviant stimulus. The thicker, black box, is an intensity deviant. Both repetition deviants and intensity deviants can have either a type A or type B fundamental frequency
