What was the procedure of Bowlby's 44 thieves study?
44 criminal teenagers accused of stealing, interviewed for signs of AP, family interviewed (prolonged separations?). Control group of non-criminal emotionally disturbed teenagers - how often maternal deprivation occurred in those who weren't thieves
5 of 9
What did Bowlby find in his thieves study?
14 of the 44 thieves APs, 12 of them experienced prolonged separation. Only 5 of remaining 30 experienced separations. Control group - 2 out of 44 had experienced long separations. So prolonged early separation caused AP

Why might the evidence for Bowlby's 44 thieves study be poor?
Drew on a no. of sources of evidence, e.g. war orphans - traumatised and poor after-care, could be the causes of later development difficulties. 44 thieves major design flaws - Bowlby biased as carried out assessments for AP and interviews himself
7 of 9
What counter-evidence is there for the theory of maternal deprivation?
Hilda Lewis partially replicated 44 thieves study, 500 young people. History of early prolonged separations didn't predict criminality - other factors may affect outcome
8 of 9
Why is the critical period that Bowlby suggests more of a sensitive period?
Damage isn't inevitable - some cases have had good outcomes if good aftercare, e.g. Koluchova - twin boys from Czechoslovakia, locked in cupboard from 18 months to 7 years, then looked after by two loving adults and recovered fully
