Some types of mild mental illnesses, such as anxiety, phobias, or panic, may be the result of a wrong learning process according to the principles of behavioral reflex in the behavioral school. It simply means that a person who is exposed to a frightening incident on a night's night, like a dog attack, may develop into a phobia of night, or darkness in general. It may develop further, if the injured person is afraid to leave his home, and no longer feel reassured only in his home, to the extent that he can not follow his work and his daily duties outside the home.
