Emily Myers (2009) performed fMRI brain imaging on subjects who were hearing and watching stimuli that produced the McGurk illusion. What aspects of the stimuli predicted selective brain activity?

Question

Quizplus · Accepted Answer

According to Emily Myers' study, some neural regions responded selectively to an abstract sound category (the McGurk effect), while other neural regions responded selectively to acoustic details even within a category. This suggests that different regions of the brain are responsible for processing different aspects of the stimuli that produce the McGurk illusion. Option A is incorrect because neural responses during the McGurk effect were different from those during trials without the effect. Option B is incorrect because auditory neural regions represented both the phonemic category and the acoustic gradient within it. Option C is incorrect because auditory neural regions did not respond to any kind of perceptible acoustic change, but rather to specific aspects of the stimuli that produced the McGurk illusion.
