Continuous maternal care is essential for healthy psychological development
Disruption or breaking of this attachment can result in serious damage to the child's social, intellectual and emotional development
Consequences are permanent and irreversible
Consequences of this disruption
Affectionless psychopathy (inability to show affection)
Low IQ
Delinquency
Acknowledged 'ifs'
Separation will only have this effect if it happens before the age of about 2 1/2 years
Infants need a continuous and intimate with a mother or a permanent substitute mother figure to ensure continuing normal mental health - must provide emotional care
Bowlby's 44 juvenile thieves - procedure
Interviewed for signs of affectionless psychopathy
Families also interviewed in order to establish whether the 'thieves' had prolonged early separation from their mothers
Control group of non-criminal but emotionally disturbed children also studied to see how often maternal deprivation occurred in 'non-thieves'
Bowlby's 44 thieves - findings
14 of the 44 identified as having affectionless psychopathy, none in the control group
86% / 12 out of the 14 had experienced prolonged separation (for at least 6 months) in their first five years of life
This kind of separation only experienced by 2 in the control group
Goldfarb study
Followed up 30 orphaned children until they were 12
Half fostered before 4 months, other half remained in orphanage
IQ tested when they were 12
Fostered children had average IQ of 96, remained in orphanage had average IQ of 68
Maternal deprivation during the critical period - mental retardation but the fostered children had an acceptable mother substitute figure so IQ returned to normal
Eval - issues with the studies
Goldfarb - children growing up in orphanage deprived of more than just maternal care e.g. proper education, food. Evidence is only correlational, any other factor could've led to low IQ later in life, can't establish cause and effect
Bowlby - conducted the interviews and assessments himself, knew what he expected to find - investigator bias, biased results
Eval - real world application
Impact on post-war child-rearing and how children are looked after in hospitals
Before, hospital visits were strongly discouraged
Bowlby, Robertson and Robertson carried out series of films showing distressed children during hospital stay
Policy change - introduced parent beds and family wings to allow parents to stay close to their children
Eval - deprivation or privation
Rutter claimed Bowlby had muddled deprivation and privation
Severe long term effects are more likely to be the result of privation (having never formed an attachment)
Should've identified whether the children he studied were simply deprived of emotional care in early childhood of whether they had not formed early attachments
Then could whether the consequences were different
Eval - psychically deterministic
Assumes that if a child experiences early prolonged separation in critical period, this will lead to development of affectionless psychopathy
Many young people around the world go on to develop 'normally'
Could be as a result of choosing to behave differently, young people have free will and resilience
Early childhood experiences do not always lead to negative consequences
