Bowlby's maternal deprivation theory (introduction)
Bowlby's theory of maternal deprivation emphasises the importance of a continuous relationship between a child and their primary caregiver for healthy emotional and psychological development
Being separated from a mother in early childhood has serious consequences (maternal deprivation)
Separation vs. deprivation (AO1)
there is an essential difference between separation and deprivation.
separation simply means the primary attachment figure is not present around the child
this only becomes a problem if the child becomes deprived of emotional care, and if it is regular, it can be very harmful
What is the critical period for psychological development?
the first two and a half years of life
What are the effects of deprivation on development?
intellectual development - Bowlby believed that if children were deprived of maternal care for too long during the critical period, they would experience delayed intellectual development / low IQ
emotional development - Bowlby identified affectionless psychopathy as the inability to experience guilt or strong emotion towards others, preventing them from developing relationships
Bowlby's 44 Thieves Study (AO1)
Bowlby studied 44 criminal teenagers accused of stealing
all 'thieves' were interviewed for signs of affectionless psychopathy
their families were also interviewed to establish whether the 'thieves' had prolonged early separation from their mothers in the first two and a half years of their life
the sample was compared to a control group of 44 non-criminal but emotionally disturbed teenagers
they found that 14 were described as affectionless psychopaths, and 12 of them had experienced prolonged separation
One limitation (AO3)
theory of maternal deprivation is based on poor-quality evidence
Bowlby's 44 thieves study is flawed because it was Bowlby himself who carried out the interviews for affectionless psychopathy
this left him open to bias because he knew in advance which teenagers he expected to show signs of psychopathy
therefore, this means that we can't generalise his findings to the wider population as it is based on highly flawed evidence
