Institutional_And_Transformative_Socialisation_Process encompasses intensive socialisation mechanisms that involve systematic transformation of individual identity, often within institutional contexts or through significant life transitions. These processes typically involve more dramatic changes in identity and social position compared to routine socialisation experiences. Resocialisation involves comprehensive transformation of values, norms, and behaviours when individuals enter new social environments with fundamentally different expectations. Degradation ceremonies represent ritualised processes designed to strip away existing identities as part of institutional control mechanisms. Adoption creates new family relationships and identities through legal and social recognition. Self-fulfilling prophecy demonstrates how social expectations can shape individual outcomes and identity formation through dynamic interaction between beliefs and behaviour. These processes highlight the power of social institutions and significant life events to fundamentally reshape individual identity and social relationships, often involving elements of both social control and personal transformation that extend beyond routine socialisation experiences.
