McGurk-effects that saturate tend to be excluded from audiovisual experiments

Evidence

First of all, the mean percentage of “ba” scores for McGurk targets over all conditions in Exp. A was computed for each subject, and participants providing mean scores larger than 95 % or less than 5 % were discarded, considering that these subjects provided either too strong or too low McGurk effects to enable binding modulations to be displayed. This resulted in discarding 8 out of 29 participants. — Dijk, Pim van, Physiology, Psychoacoustics and…, 5163

• DEFINE: Clarifies the McGurk effect as a perceptual fusion where the auditory ‘ba’ and visual ‘da’ are perceived as ‘da.’
• SEED: Angle: experimental design choices like ceiling-exclusion silently shape reported effect sizes in perception science.
