Mary Ainsworth produced a method to assess the strength and quality of an attachment.
The aim of her study was to observe attachment security. This was done through measuring 5 key attachment behaviours.
The methodology used consisted of a room with controlled conditions. The room also display a two-way mirror through which psychologists could observe the infant's behaviours alongside the camera's recording observation to allow for greater thematic analysis and later peer review.
The five behaviours measured consisted of proximity seeking (infants with good attachments will seek proximity to their caregiver), reunion behaviours (following a short separation with their caregiver) exploration and secure base behaviours (as infants with good attachments will freely explore and view their caregiver as a comfort) stranger anxiety (anxiety displayed when a stranger approaches)and seperatio anxiety (when their caregiver leaves).
The procedure consisted of 7 episodes, lasting 3 minutes each. To begin with the infant and caregiver entered the room.
First episode
1. Infant is encouraged to explore room
2. Measuring exploration + secure base behaviours and proximity seeking
