Attachment의 반대개념인 줄 알았는데, 아니네..
그것도 2가지 sense나 있다. ㅋ
wiki에서 퍼온 설명...
Emotional detachment, in psychology, can mean two different things. In the first meaning, it refers to an "inability to connect" with others emotionally, as well as a means of dealing with anxiety by preventing certain situations that trigger it; it is often described as "emotional numbing" or dissociation, depersonalization or in its chronic form depersonalization disorder. In the second sense, it is a type of "mental assertiveness" that allows people to maintain their boundaries and psychic integrity when faced with the emotional demands of another person or group of persons. These senses are within the framework of psychology and academia, not those of everyone else in the world.
Second sense: mental assertiveness
Emotional detachment in the second sense above is a positive and deliberate mental attitude which avoids engaging the emotions of others. It is often applied to relatives and associates of people who are in some way emotionally overly demanding. A simple example might be a person who trains himself to ignore the "pleading" food requests of a dieting spouse. A more widespread example could be the indifference parents develop towards their children's begging. It is not to be confused with being wilfully cold or unpleasant, because it is a positive mental attitude. Of course, the decision as to whether emotional detachment in any given set of circumstances is considered to be a positive or negative mental attitude is a subjective one, and therefore a decision on which different people may not agree.
This detachment does not mean avoiding the feeling of empathy; it is actually more of an awareness of empathetic feelings that allows the person space needed to rationally choose whether or not to be overwhelmed or manipulated by such feelings.
