This area of study examines the disruption of attachment bonds, distinguishing between deprivation (loss of an existing bond) and privation (failure to form any bond). Central to this is Bowlby’s Maternal Deprivation Hypothesis (1951) and the subsequent challenge provided by Rutter’s research into institutionalisation, specifically the English and Romanian Adoptee (ERA) study. Candidates must assess the short-term effects (separation anxiety, PDD model) and long-term consequences (affectionless psychopathy, disinhibited attachment, intellectual underfunctioning). Crucially, the scope includes the debate on reversibility and the shift from a 'critical period' to a 'sensitive period' in developmental psychology.
