Bowlby's Theory of Maternal Deprivation

Cards (6)

  • separation vs deprivation
    • separation - the child is not in the presence of the primary caregiver, brief separations, particularly when the child is with a substitute caregiver, don't have a significant impact on development
    • deprivation - the child loses an element of the primary attachment figure's emotional care/love, this then becomes an issue for development
    • extended separations can lead to deprivation, which causes harm
  • Bowlby's maternal deprivation hypothesis
    • the crucial time for a child's psychological development is 30 months
    • if a child is deprived from their mother during this time, it can lead to serious psychological harm
  • 44 thieves - procedure
    • Bowlby selected a sample of cases from the many children he had worked with at his clinic in London
    • he identified 44 thieves (14 of which were classed as psychopaths) and 44 non-thieves for comparison
    • he recorded the number who had experienced frequent sepearations from their mother before aged 2
  • 44 thieves - findings
    • 86% of affectionless thieves experienced frequent separations before age 2, compared with 17% of other theives and 4% of controls
  • 44 theives - conclusions
    • maternal deprivation is linked to criminality and perhaps to emotionless psychopathy
  • evaluation
    • generalisable as it supports his maternal deprivation theory
    • could hinder his results as it is his own research supporting his own theory so it may be bias as he may have interpreted his results differently (researcher bias) - lacks internal validity
    • Levy et al supported this as he found that when baby rats were separated from their mothers for even just a day, this had a permanent impact on the social development - supporting Bowlby (external validity)
    • Bowlby's study had a positive impact on how people thought about childrearing post war - Robertson filmed a two year old girl during her 9 day stay in a hospital and found that she was frequently distressed and begging for her mother - high external validity
