Attachment theory is increasingly cited by developmental and clinical psychologists as a framework for understanding the impact of emotional ties on individuals throughout their lives. With her pioneer research into the nature of infant-caregiver attachments, Mary Ainsworth provided both the methodology and data for future investigations of how early experiences affect personality development. The laboratory procedure, "The Strange Situation," she devised is a widely used assessment device for gauging the nature of early attachments. This production includes biographical information about Mary Ainsworth, Bowlby's influence upon her work, and the influence ethologists Lorenz and Harlow had upon them both. Enchanting visuals from Ainsworth's observational study of mothers and babies in Uganda in 1955, telling footage of secure and insecure attachments in The Strange Situation, and a portion of the Adult Attachment Interview make this film a rich introduction to attachment theory and one of its most important researchers. DVD, 38 min. Closed-Captioned.
