The McGurk effect describes how our vision influences our hearing
What we see can influence what we hear. This phenomenon is described in the McGurk effect.
The McGurk effect is an example which shows, how much our brain can influence our perception – see also Every object, even an apple, is essentially a colorless object.
The strength of the effect differs across languages. Dutch, English, Spanish, German, Italian and Turkish language listeners experience a robust McGurk effect; Japanese and Chinese listeners, weaker.
The reason, why Chinese and Japanese listeners experience a weaker version of the McGurk effect could be, that their cultures often times includes face avoidance, which might diminish the effect.
