The Learning Viewpoint assumes that abnormal behavior is due to a persons past experiences which they have subsequently learned to associate with a particular emotion.
Experiences we have during our childhood can cause us to become drawn to, or repelled from, similar situations in adulthood. For example, a person who was locked in a dark room when they were younger, could have a fear the dark as an adult.
The learning viewpoint is most useful for dealing with disorders such as phobias which commonly have been acquired through past traumatic experiences. Fortunately, many phobias can be successfully treated using various methods and NLP techniques.
