The McGurk effect shows that not only our brains are integrative but also that what we see can influence what we hear. Our brains are integrative; this means that that our brains incorporate different information it receives from sensory stimuli, in this case hearing and vision. This can change what we perceive from what is really there, for example in the McGurk effect we believe that we hear different sounds coming out of the moving mouth, but in actuality there is only one sound that is being repeated, which we hear when we close our eyes. The article on brain mechanisms used for interpreting speech writes that researchers have identified an area in the brain known as Broca’s region that is used for talking. They write that “When the speech sounds do not correspond exactly to the words that are mouthed, the brain often conjures a third sound as an experience.” This means that the brain will create an experience that was not initially there, and we will perceive it even though it is totally different

Unformatted text preview: from what the real stimuli was. Hasson explains, “speech is not as clear as print, it must be interpreted rather than simply recognized.” These interpretations are carried out in the brain, believed to be in Broca’s region. When the speech is unclear, then the brain’s interpretations will be important, even if they are not accurate. So why does our brain do this? It does so in order to improve our ability to hear unclear speech. If we are not able to clearly understand ones speech our brain plays an important role in trying to decipher what that word or syllable was, and therefore it integrates information from different sensory input to do so.
