The Strange Situation is a laboratory procedure devised by Mary Ainsworth in the 1970s to observe attachment between a caregiver and child. In this procedure, the infant is exposed to a series of eight separation and reunion episodes to assess the quality of attachment. In the Strange Situation, the baby is observed in a room with the mother and a stranger, as these two social partners have different levels of familiarity to the child and can evoke different reactions from the child, which are relevant to understanding the child's attachment style. The presence of the mother and the stranger, as well as their interactions with the baby, allow the observer to evaluate the baby's behavior in different situations and provide insights into the quality of attachment.
