Generally, internalization is the long-term process of consolidating and embedding one’s own beliefs, attitudes, and values, when it comes to moral behavior. The accomplishment of this may involve the deliberate use of psychoanalytical or behavioral methods.
When changing moral behavior, one is said to be "internalized" when a new set of beliefs, attitudes, and values replaces or habituates the desired behavior. For example, such internalization might take place following religious conversion.
