Schizophrenia

John was very maladaptive. An example of him being maladaptive in the movie is when he went to a new class he didn't adapt to it very well and was very socially awkward. He is also unjustifiable. When he put his baby in the bathtub and left it running without being in there, there was no reason for him to be doing that other than the fact that he has schizophrenia and that's not a good explanation for it. He also had a lot of times that he was quite disturbing to people. An example of this is when he thought that a person was holding a gun to his wife's head he pushed her and her baby to the floor and his wife found that very disturbing for him to do. Atypical was also something that he was. When he was outside of the college and running around talking to himself in front of a bunch of people those people thought he was being very irregular.
