The negative consequences of even single and short-term instances of exclusion have been widely documented across a variety of psychological and physical domains; including effects on emotions, cognition, behaviour, and health. Specifically, exclusion threatens a fundamental human need to belong that reflexively elicits negative emotions, impairs cognitive abilities, increases self-control failure, and aggression.
Mostly relevant to these negative outcomes, however, is how people respond to it. Individuals can cope with exclusion in functional ways, thus ultimately increasing their chances for social inclusion or in dysfunctional ways, promoting a vicious cycle of exclusion, maladaptive responses, further instances of exclusion, and social isolation.
