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 decision to avoid engaging emotional connections, rather than an inability to do so, typically for personal, social, or other reasons. In this sense it can allow people to maintain boundaries, psychic integrity and avoid undesired impact by or upon others, related to emotional demands.
