These cognitive disorders may be related among themselves by faulty learning since several research studies have shown that the brains of autistic individuals have abnormalities in the cerebellum which plays a role in procedural learning. In keeping with this view one may postulate the possibility that declarative memory replaces faulty procedural memory in some of its functions which implies making conscious efforts in order to perform actions that are normally automatic.
