The model estimated detection of a difference between original sound and target sound (reference level: Stimulus State same) as a function of Stimulus Variant (Speech, Song, Intermediate. Reference level: Speech) and Musicality as assessed by the GoldMSI questionnaire and z-transformed (that way the estimates refer to an individual with average musicality).
