Mary Ainsworth is most famous for her theory of attachment. She begin her major study in 1970. Ainsworth came up with an assessment that explained how attachment might vary between children, called strange situation classification, SSC. Through her experiments using SSC she was able to find three distinct styles of attachment that included one of secure attachment and the other two insecure attachments; she then identified these attachments as: Secure, avoidant, and resistant. 70% of infants have secure attachment. When dealing with separation anxiety the infant will feel distressed when the mother leaves. When dealing with stranger anxiety the infant will be avoidant of strangers when alone but friendly when the mother is around. Lastly when dealing with reunion behavior the infant will positively and happily return to their mother. 15% of infants have resistance attachment. When dealing with separation anxiety the will show signs of intense distress when the mother is not around. When dealing with stranger anxiety the infant will avoid strangers and show fear towards them. Infants dealing with reunion behavior will approach mother but show resistance. And the 15% have avoidance attachment. Dealing with separation anxiety, the infant will show no sign of distress with the mother is not around. When dealing with stranger anxiety the infant will be okay with the stranger and plays normally with the stranger present. Finally when dealing with reunion behavior the infant will show little interest that the mother has returned. She suggested that the type of attachment a child will have depends on the behavior of the primary career. Her findings provided the first empirical evidence for the “Bowlby’s attachment theory.
