Bowlby's 44 thieves study supported his theory of maternal deprivation
Bowlby's 44 thieves study is a correlational study (limitation)
not a controlled experiment, as its not possible
causation can't be established
factors such as socio-economic status, family criminal history, or inherited mental health conditions could have influenced the likelihood of maternal deprivation in infancy and later offending by the children
Strength - Bowlby's work on attachment has social impacts
influencing publicpolicy and socialwelfare systems
e.g. hospitals altered policies for hospitalised children to allow for a consistent caregiver presence
Counterpoint - Bowlby's work on attachment impacts on economy
nurseries are more expensive
focus on maternity rather than paternity leave may have resulted in an increase in the gender pay gap
Limitation - criticisms of gender bias
focus on the mother as the primary caregiver potentially downplays the contribution fathers and other caregivers can make in a child's emotional development (alpha bias)
Schaffer et al. have found 87% of infants can form multiple strong attachments at 18 months
Other research indicates important roles for the father in early attachment such as encouraging risk taking, developing socialisation and the sensitive responsive role
