The idea that the continual presence of care from a mother or caregiver is essential for normal psychological development for babies and toddlers.
Emotionally and intellectually.
Separation in early childhood = serious consequences.
Separation:
The child isn’t in the presence of the primary attachment figure e.g the mother passed away.
Deprivation:
When the mother is there but could be depressed. The child isn’t receiving anything from them.
E.g getting no love in return. Deprived of emotional care.
The Critical Period:
Bowlby saw the first two and a half years of life as the critical period for psychological development.
If a child is separated from their mother in the absence of a suitable substitute care and so deprived of her emotional care for an extended duration during this period Then Bowlby believed that psychological damage was inevitable.
Continuing risk up to the age of 5.
Effects On Development:
Intellectual development
If children were deprived of maternal care for too long during the critical period they would experience delayed intellectual development, characterised by abnormally low IQ.
Demonstarted in studies adoption. Goldfarb found lower IQ in children who had remained in institutions as opposed to those who were fostered and thus had a higher standard of emotional care.
Effects On Development:
Emotional development
Affects children in their emotional development.
Bowlby identified affectionless psychopathology as the inability to experience guilt or strong emotion towards others. This prevents a person developing fulfilling relationships and is associated with criminality.
Affectionless psychopaths cannot appreciate the feelings of victims and so lack remorse for their actions.
