What does Bowlby’s theory of maternal deprivation focus on?
The idea that continuous emotional (maternal) care from a mother (or mother-substitute) is necessary for normal emotional and intellectual development
What is the difference between ‘separation’ and ‘deprivation’?
Separation = the child not being in the presence of the primary attachment figure
Deprivation = losing emotional care as a result of the separation
How does separation turn into deprivation?
Brief separation, especially when the child is with a substitute caregiver who can provide emotional care, are not significant for development but extended separation can lead to deprivation, which can cause harm
Describe the critical period
Bowlby saw that the first two and a half years as a critical period for psychological development
If a child was separated from their mother in the absence of suitable care and so deprived of her emotional care for an extended duration during this critical time, Bowlby believed psychological damage was inevitable
Bowlby believed the risk continued up until the age of 5
What are the 2 ways maternal deprivation effects development?
Intellectual development and emotional development
How does maternal deprivation affect intellectual development?
If a child is deprived of maternal care for too long during the critical period they would experience delayed intellectual development and abnormally low IQ
This has been demonstrated in studies of adoption
Goldfarb (1947) found lower IQ in children who had remained in institutions as opposed to those who were fostered (in a higher standard of emotional care)
How does maternal deprivation affect emotional development?
Bowlby identified affectionless psychopathy as the inability to experience guilt or strong emotion towards others
This prevents a person developing fulfilling relationships and is associated with criminalilty
Affectionless psychopaths cannot appreciate the feelings of victims and so lack remorse for their actions
What did Bowlby’s research ‘44 thieves’ look at?
The link between affectionless psychopathy and maternal deprivation
Describe Bowlby’s 44 thieves procedure
44 criminal teenagers all accused of stealing
‘Thieves’ were interviewed for signs of affectionless psychopathy (lack of affection, guilt and empathy)
Families were interviewed to establish whether the ‘thieves’ had prolonged separation from their mothers
Sample was compared to a control group of 44 non-criminal but emotionally disturbed young people
What were the findings of Bowlby’s 44 thieves study?
14 of the 44 thieves could be described as affectionless psychopaths
12 of these had prolonged separation from their mothers in the first 2 years of life
Only 5 of the remaining 30 ‘thieves’ had experienced separations
Bowlby concluded that prolonged early separation/ deprivation caused affectionless psychopathy
Give a strength of maternal deprivation
Animal studies - Levy et al showed that separating baby rats from their mothers for as little as a day has permanent effect on their social development
(Limitation) - however, can animal studies be generalised to human behaviour?
Give 2 limitations of maternal deprivation?
How many thieves out of the “44 thieves” can be described as affectionless psychopaths?
14
How many thieves out of the 14 that were described as affectionless psychopaths had prolonged separation from their mothers in the first 2 years of their life?
12
How many out of the remaining 30 thieves had experienced separation?
5
