Familiar consonant final intervals hinder deviant-tone detection relative to small ones

Evidence

Posthoc multiple comparison analysis showed performance for musically important final intervals (perfect fourth and fifth, 5 and 7 semitones, respectively) was significantly lower than that for 1 semitone. — Dijk, Pim van, Physiology, Psychoacoustics and…, 5312

• QUESTION: Counterintuitive — musical training and consonance expectations usually help, so why did perfect fourths/fifths impair detection compared to a 1-semitone final interval? Worth chasing the mechanism.
