Some forms of social influence produce public compliance - an outward change in
behaviour and expressed attitudes in response to a request from another person, or as a
consequence of persuasion or coercion. As compliance does not reflect internal change, it
usually persists only while behaviour is under surveillance. For example, children may obey
parental directives to keep their room tidy, but only if they know that their parents are
watching! An important prerequisite for coercive compulsion and compliance is that the
source of social influence is perceived by the target of influence to have power; power is the
basis of compliance (Moscovici, 1976).
