A measurement technique designed by Ainsworth to assess the quality of an infant’s attachment to a caregiver. Infants (12 months or older) and their caregivers are brought to a room (the strange situation) where the child experiences a series of eight 3-minute episodes, each one introducing changes in the social situation, some of which are likely to be stressful, such as an episode when the mother leaves the baby with a stranger. The infant’s willingness to explore the toys and his reactions to his mother and the strangers are observed.
