Bowlby’s theory of maternal deprivation. Effects of institutionalisation,…

The idea

Bowlby’s theory of maternal deprivation posits that continuous maternal care is essential for normal psychological development. Prolonged separation during the critical period (first 30 months) without a substitute caregiver causes irreversible intellectual (e.g., abnormally low IQ) and emotional damage, notably affectionless psychopathy. Institutionalisation refers to the effects of living in an orphanage or hospital where children lack a primary attachment figure. Rutter’s English and Romanian Adoptees (ERA) project studied orphans who experienced extreme institutionalisation. Findings revealed that children adopted after six months showed significant deficits, including disinhibited attachment (indiscriminate friendliness) and delayed intellectual development, highlighting the severe, long-term impacts of early deprivation.

What earns the marks

• Define maternal deprivation as the loss of emotional care normally provided by a primary caregiver during the critical period.
• Identify affectionless psychopathy (inability to experience guilt or strong emotion) as a key emotional consequence of maternal deprivation.
• Explain the effects of institutionalisation, specifically disinhibited attachment and physical or intellectual underdevelopment.
• Describe the findings of Rutter's ERA study, noting that recovery depends on the age of adoption (before or after six months).
• Evaluate Bowlby's theory using evidence, such as Lewis's replication of the 44 thieves study which found no link between early separation and later criminality.

Common mistakes and how to put them right

• Confusing maternal deprivation with privation.

  Put it right: Deprivation is the loss of an existing attachment, whereas privation is the failure to form any attachment at all.

• Stating that Rutter's ERA study investigated maternal deprivation.

  Put it right: Rutter actually studied institutionalisation, which involves privation rather than deprivation.

• Claiming that all institutionalised children suffer permanent damage.

  Put it right: Rutter found that children adopted before six months often caught up developmentally with their British counterparts.

Exam tips

• When evaluating Bowlby's theory, explicitly distinguish between deprivation and privation to demonstrate higher-level critical thinking.
• Use specific data from Rutter's ERA study, such as the critical six-month cut-off for adoption, to support points about recovery from institutionalisation.
• Link the concept of affectionless psychopathy directly to Bowlby's 44 thieves study when discussing the emotional consequences of maternal deprivation.
