Transposing a tone pattern impairs detection, while exact repetition does not help.

Evidence

There was a main effect of block (F(6,294) = 41.61, p < 0.001, ε = 0.790, partial η2 = 0.459). The effect of transposition (contrasting block 1 with the average of blocks 5 and 6) was significant (t = ‑10.36, p < 0.001). The effect of one exact repetition (contrasting block 2 with block 6) was not significant (t = 0.59, p = 0.559). The effect of variance in interval range (contrasting block 7 with the average of blocks 4 and 6) was significant (t = 3.20, p = 0.002). — Dijk, Pim van, Physiology, Psychoacoustics and…, 5312
