The intensity of auditory distractors: It does make a difference

If you stop by my poster—I hope you do—I will show you the results of a recent preregistered replication study, which made an interesting combination of expected and unexpected results. In this study, we systematically examined the role of intensity in two types of auditory distraction. The first type of distraction is the changing-state effect (i.e., increased disruption by changing-state relative to steady-state sequences). The second type is the auditory deviant effect (i.e., increased disruption by auditory deviant relative to steady-state sequences). In previous experiments, the changing-state effect was independent of intensity. Our results confirmed this. Somewhat unexpectedly, however, we also found a main effect of intensity. Steady-state and changing-state sequences presented at 75 dB(A) were more disruptive than presented at 45 dB(A), suggesting that loud auditory distractors are more difficult to ignore after all, which may not sound all that surprising, but is at odds with all previous results. We also tested whether an unexpected increase in intensity is equally disruptive than an unexpected decrease. It was.
