The Minnesota child-parent study found early continuity between early attachment and later emotional/social development.
Individuals classified as securely attached in infancy were less isolated, more popular and more empathetic.
Bullying
Bullying behaviour can be predicted by attachment type. Myron-Wilson and Smith (1998) assessed attachment type and bulling involvement using questionnaires in 196 children aged 7-11 from London.
- Secure were unlikely to be involved
- Insecure avoidant were most likely to be victims
- Insecure resistant were most likely to be bullies
