Asociality
（重定向自Asocial personality）
Asociality refers to the lack of motivation to engage in social interaction, or a preference for solitary activities. Developmental psychologists use the synonyms nonsocial, unsocial, and social disinterest. Asociality is distinct from but not mutually exclusive to anti-social behaviour, in which the latter implies an active misanthropy or antagonism toward other people or the general social order. A degree of asociality is routinely observed in introverts, while extreme asociality is observed in people with a variety of clinical conditions.
