From: Audiovisual integration in the McGurk effect is impervious to music training

 

Proverbio, Massetti, Rizzi & Zani (2016)

Current study

Conclusion

No McGurk effect in musicians

Stronger McGurk effect in musicians than non-musicians

Music training does not affect the McGurk effect

Stimuli

Audiovisual + auditory only

audiovisual congruent + audiovisual incongruent + auditory only

audiovisual (congruent + incongruent)

Task instruction

Write down “what they had heard”

answer through keyboard “what sound they believed they heard”

Answer what the person said (forced choice)
