Charlie's therapist is using a technique known as CBT Cognitive Behavioral Therapy.
Explanation:
Cognitive Behavioral tecnique is often used to treat phobias, among other emotional or psychological afections. This tecnique is based on how negative emotionds and thoughts can be shaped into possitive ones, and so this can help deal with phobias or ansiety.
What Charlie's therapyst is doing is helping him relate his fear of hights with something nice and relaxing, that is how according to this tecnique people can overcome his fears by changing the idea of hights as a bad thing.
This tecnique works under the premise that behvior can be shifted with cognitive influence, this theory helps change thoughts that influence fear.
This involves viewing the individual as a holistic being rather than a diagnosis or parts to be fixed. This involves looking broadly into the individuals lifestyle, emotional status, environmental factors, age, ethnicity, health history etc. rather than just focusing on the illness, injury or disease.
