Explanation:

There can be many approaches to psychotherapy and studying psychology in general. For example, cognitive and behavioral perspective. Here, Dr Abbot is focusing on the behavior of individuals according to their environment. They can develop normal or abnormal behavior according to the conditioning provided to them.
