Long-term Effects of Early Attachment
Your attachment style from infancy doesn't just disappear - it creates an internal working model that influences relationships throughout your entire life. Hazan and Shaver's newspaper study of 620 adults found fascinating connections between childhood attachment and romantic relationships.
Securely attached individuals tend to have longer-lasting romantic relationships and show better social competence in childhood friendships. They're more popular, empathetic, and less aggressive than their insecurely attached peers. However, it's worth noting that attachment styles can change - they're not set in stone forever.
Cultural variations exist too - research by Van Ijzendoorn and Kroonenberg found that Britain has the highest percentage of secure attachment, whilst China shows the lowest. Germany has high avoidant rates, and Israel shows high resistant attachment patterns.
Remember: This research shows correlation, not causation - poor parenting might cause relationship difficulties, but other factors could be involved too.
Maternal Deprivation and Institutionalisation
Bowlby's maternal deprivation hypothesis argued that separation from the primary caregiver during the first 30 months causes inevitable psychological damage. His famous 44 thieves study found that 12 out of 14 'affectionless psychopaths' had experienced prolonged separation from their mothers.
Effects of institutionalisation are particularly severe - babies in institutions receive less individual attention, leading to developmental delays and higher rates of disinhibited behaviour. However, individual differences matter enormously - some children recover better than others when moved to more nurturing environments.
The research has real-world applications though. Bowlby's work revolutionised hospital care, ensuring parents can now visit their children regularly. Rutter's later research refined our understanding, showing that it's the quality of care that matters most, not just separation from the biological mother.
