Ainsworth identified three different types of attachment.
Securely attached - These children are happy when the mother is present, distressed by her absence, went to her quickly when she returned and the stranger could provide little comfort.
Insecurely attached – there were two types of insecure attachment.
Anxious avoidant – avoided the mother, indifferent to her presence or absence, greatest distress when child alone, a stranger could comfort just as well as the mother.
Anxious resistant – Seemed unsure of the mother, more anxious about mothers presence, distress in her absence, would go to her quickly when she returned then struggled to get away, also resisted strangers.
