Answer:
Psychodynamic
Explanation:
The psychodynamic approach to psychopathology postulates that the mental disorders are caused due to the repression of thoughts from the experiences of the person's past. The repression causes the person to have a panic attack. Sigmund Freud was a key figure in the development of this approach.
The statement here says that mental disorders are caused as the result of unresolved unconscious conflicts of the past.
Hence, Dr. Noonan believes in the psychodynamic approach to psychopathology.
