This is the email I sent my professor. I would like to research the topic of night owls and morning people. If it’s true that night owls are more prone to mental disorders. Possibly the existence of different brain structures due to their chronotypes. Also from a biological perspective why some species sleep at night and some are awake throughout the night. I will look at at least one of these three assessment tests that are used in this area and look into the validity of these test(s). The Horne and Ostberg morningness–eveningness questionnaire, Pittsburgh Sleep Quality Index,and Epworth Sleepiness Scale. Also I need to some articles that talk about the surveys and main topic which should not be a problem because they should be part of the references in the paper
