The document discusses Ainsworth's identification of three main types of attachment: secure attachment, insecure-avoidant attachment, and insecure-resistant attachment. It then provides a case study describing the behaviors of two brothers, Rob and Sam, and asks the reader to identify the type of attachment each boy demonstrates. Rob is identified as having an insecure-resistant attachment as he cried and seemed scared around strangers, while Sam displayed a secure attachment by happily greeting his mother and being comfortable with other adults. The document evaluates the strengths of Ainsworth's Strange Situation experiment in reliably identifying attachment types, and also notes limitations, such as additional types of attachment identified by others and concerns about its cultural specificity.
