M Barrie, Peter is very immature and lacks the capacity to form mental representations. Because of this he is amnesic. He is unable to form episodic memories though he has acquired certain skills such as steering a boat. He knows certain facts including facts about himself but does not how he comes to know these facts. He has difficulty recognising people but knows that they are familiar to him. He has some memory of emotions and desires. See also Central nervous system Neuroimaging References External links
