Audio problem: When Norman is talking to his "Mother" on the phone, the camera (in Mary's point-of-view) comes in the room and Norman says, "How could you think such a thing. I would never do such a thing," but you can see Norman's reflection in the big mirror hanging in the lounge room and you can see his mouth isn't moving. (01:33:00)
Psycho II (1983)
1 audio problem - chronological order
Directed by: Richard Franklin
Starring: Robert Loggia, Anthony Perkins, Vera Miles, Meg Tilly
Revealing mistake: At the end when Norman is being stabbed at by Mary dressed up as Mother, Mary stabs Norman in the hand. You can plainly tell that this hand is a doll, as it is not a natural colour, it is stiff and is stationary, unlike Norman who is moving his hands. (01:35:10)
Mary: You really wanna know what Norman's like?
Warren Toomey: Yeah.
Mary: Better than you'll ever be, fat boy.
Trivia: When Mary and Norman go into Mother's room, before Mary turns on the light look at the shadow on the wall on the right. It is a silhouette of Alfred Hitchcock, the director of the original "Psycho" (1960). (00:24:10)

Chosen answer: The murderer is Emma Spool, Norman's biological mother. She was killing people because she didn't want anybody harming Norman.
Emma was not Norman's biological mother. She was the sister of Norma (and Norman's aunt) and jealous that Mr. Bates chose Norma over her and thought Norman should have been the son she and Mr. Bates were suppose to have. Later, while still mentally ill, she believed Norman was her son and told Norman this.

Emma Spool was, in fact, Norman's biological mother. It was revealed at the end of the movie that she is his real mother and Norma Bates is her sister who adopted Norman and raised him While Emma was institutionalized.

Again, that was just Emma being delusional and/or lying. Tracy Venable tells Norman the truth in Psycho III. Emma was never his mother.

I never knew Emma Spool was Norman's biological mother. In fact, I never heard of Emma Spool. Thanks.
