Deviant pitch patterns were detected from the last interval of a six-tone sequence.

Evidence

Each trial consisted of four patterns separated by 700 milliseconds (ms) silence, and each pattern consisted of six tones. Three of the patterns had the same sequence of pitch intervals (standard pattern); the last pitch interval of either the final or the penultimate pattern of the trial deviated from the other three. A different standard pattern was delivered on each trial and no pattern was used more than once in the experiment. — Dijk, Pim van, Physiology, Psychoacoustics and…, 5294
