This video allows us to experience a normal stop at a cafe, but perceiving it through the eyes of a girl with autism. This demonstrates something called sensory overload. Carly's receptors in her brain for sound, vision, smell, and emotions are all firing rapidly; more than the normal person, and it's very overwhelming. She is inaudible so the part of her stimulus/input - receptor - perception - action process is over sensitized in the receptor and perception portions, and disrupted in the action portion. People with autism often have to endure this, and in this particular case, the girl can not even express her discomfort or agitation. The way she perceives things here is the same way a normal person does, only on a much larger scale.
