I already posted three times, but came across a video of the McGurk effect that is mentioned in the book and really wanted to share it. The McGurk effect refers to when what you see by reading lips while simultaneously listening to a similar sound overrides the auditory sound. I have watched the video that I linked multiple times and when watching the video at the with my eyes closed, I hear ba the whole time, but when I look at him, his mouth movement influences what I am hearing. In the comments below the video, I read that many people still hear ba, even when his mouth is wording something else. I am curious if anyone else hears ba the whole time.
