A person who has a detachment from social relationships and a restricted range of emotional expression in interpersonal situations is considered a schizoid personality. This can be verified by four out of seven symptoms. These symptoms are: a loner-always chooses solitary activities, doesn't want or enjoy any close relationships-including family, has very little interest in having sexual experiences with another person, has no close friends except for immediate family, demonstrates emotional coldness and detachment, takes enjoyment in very few activities, and appears indifferent to what others think of him/her.
