Statistical-change detection can be isolated with stimuli lacking all systematic cues except marginal probability

Evidence

We designed a broadband stimulus, composed of tone-pips, whose occurrence is only constrained by a frequency marginal probability. While the central ‘textural’ property of solely statistical predictability is maintained, it is devoid of most other systematic properties, such as frequency modulation, across channel or temporal correlations. A change is introduced by modifying the marginal distribution at a random time during the stimulus presentation, which subjects are asked to report. — Dijk, Pim van, Physiology, Psychoacoustics and…, 3285
