The process by which people concentrate on particular skill areas to compensate for losses in other areas is called selective optimization. It is a common occurrence in people where they tend to focus more on what they know they are good at and continue improving that area.
Psychology is a study of human behavior and mind, both conscious and unconscious. This study may be enriched by the knowledge of cultural differences because the differences allow us to better understand the behavior and the way others think. We will not then be easy to judge other people by the way they are.
