Bowlby's theory of maternal deprivation

  • Maternal deprivation refers to the separation between a caregiver and a child

  • The consequences of maternal deprivation can be emotional and intellectual

  • The theory of maternal deprivation was proposed by Bowlby (1953) stating that "mother-love in infancy and childhood is as important for mental health as are vitamins and proteins for physical health"

  • It is now understood that there are long-term effects of prolonged separation from a primary caregiver

    • This is primarily due to the absence of emotional care

Bowlby's 44 thieves study

  • As part of his research, Bowlby (1944) conducted the '44 Thieves' study

  • Procedure

    • Bowlby studied 88 children from the Child Guidance Clinic, London, who were emotionally maladjusted

      • Half of the children, 44, were accused of stealing (thieves)

      • The other 44 made up the control group

    • All thieves were interviewed for signs of being affectionless psychopaths

    • Bowlby suggested that this characteristic enabled the children to be thieves

    • Families were also interviewed by Bowlby to establish whether the thieves had had prolonged periods of separation from their caregiver(s)

      • Separations were due to continual or repeated stays in hospital or foster homes with few visits from their family

    • The thieves' data was compared to that of the control group

  • Findings

    • Bowlby categorised 14 of the 44 thieves as affectionless psychopaths, of these 12 (86%) had experienced prolonged periods of separation from their caregivers in the first two years of their lives

    • Five (17%) of the remaining thieves had experienced prolonged separation

    • 40% of the thieves group had experienced early separation from their caregivers

    • Of the control group, only two had experienced prolonged separation

    • Bowlby concluded that prolonged and early separation from caregivers is linked to affectionless psychopathy

Bowlby's 44 Thieves findings

Separation and deprivation

  • Separation is not the same as deprivation

    • Separation is when the child is not in the presence of their primary attachment figure

    • Deprivation refers to a lack of emotional care (this can happen when a caregiver is present)

  • Separations from caregivers do not have a significant effect on child development as long as during the separation the infant has a substitute caregiver who can offer nurture, comfort and emotional care

    • Physical care: food, warmth and safety are not enough

  • Extended separations can lead to deprivation which can cause emotional and developmental harm

The critical period

  • Bowlby proposed that the first two years of a child's life are a critical period in emotional and psychological development

  • Prolonged or frequent separation from the primary caregiver during this critical period and experiencing deprivation of emotional care may lead to psychological damage

    • For the separation and deprivation to have negative effects, it means that no other substitute caregiver meets the emotional needs of the infant

  • Bowlby suggested that the risk of psychological damage continued until the age of five years old

Consequences on development

  • Bowlby suggested that maternal deprivation would lead to consequences on intellectual and emotional development

  • Intellectual development:

    • Bowlby believed that prolonged separation and deprivation would lead to delays in intellectual development, shown by an extremely low IQ

    • Goldfarb (1974) studied children from orphanages and found that children who were not adopted had lower IQs than those who were either fostered or adopted

  • Emotional development:

    • Bowlby characterised those who had delayed or limited emotional development as affectionless psychopaths

      • Affectionless psychopaths lack emotion or affection toward others and lack remorse for their actions

    • The consequences of emotional development issues are difficulties in developing normal relationships and are associated with criminality

Evaluation

Strengths

  • Bowlby's study changed how people thought about rearing and caring for children

    • The research conducted by Bowlby had a positive impact on how children were treated during separation from their parents, particularly during hospital stays

    • Bowlby's research led to a social change in how children were cared for in hospital

    • This means that there are real-world applications to Bowlby's research as it highlighted the importance of maternal care

  • Studies show support for Bowlby's findings on maternal deprivation

    • Research into women who had experienced separation from their mothers for at least a year found that 25% experienced depression or an anxiety disorder, compared with 15% of a control group (no separation)

    • The results also showed that the intensity of mental health issues was far greater in those who had experienced separation before the age of six years

    • This supports Bowlby's idea of a critical period and the idea that maternal separation has long-lasting consequences

Limitations

  • The evidence for 44 thieves study is flawed

    • Bowlby conducted the interviews with the children and the families himself

    • This could lead to bias in the findings as he may expect certain children to be affectionless psychopaths

    • Today this conclusion would be deemed unethical

    • These factors mean that the study is distorted by investigator effects

  • Bowlby may have confused deprivation with privation

    • Deprivation occurs when an attachment that has already been formed has been broken (the infant is deprived of the attachment or emotional care they once had)

    • Privation is the absence of something desired or needed

    • Rutter (1981) observed that the association of affectionless psychopathy is more likely a result of privation, rather than deprivation

      • The children of the 44 thieves study had disrupted early lives and may never have formed attachments in the first place

      • This suggests that Bowlby may have placed too much cause on the effects of deprivation on children's development

Examiner Tips and Tricks

Remember there is a difference between evidence being correlational and causational. Although there may be a link between maternal deprivation and affectionless psychopathy, it does not indicate that maternal deprivation causes affectionless psychopathy. Correlation does not equal causation!
