Discusses difficulties in telling things apart in the same category. Fusiform gyrus allows us to identify different objects and people from each other. For example, babies are very focused on faces and are hardwired to be attracted to faces, especially ones they are familiar with. Prosopagnosia can be caused by a genetic disorder, but it is probably a result of multiple genes. Levels of oxytocin can be inked to disorders like autism. Low levels of oxytocin can be reason that autistic individuals have a difficult time bonding with others. : people with autism tend to avoid faces and eyes people being affected by oxytocin look into eyes and faces more. William"s syndrome is caused by a specific genetic abnormality (26 genes are deleted) These individuals seem to have the opposite behavior of autism; they are overly social and overly interested in people. They can be classified as lacking social inhibition and usually have a lower iq by 10-20 points.
