Mary Ainsworth was a psychologist born in 1913 who studied maternal-infant attachment. She worked with John Bowlby at the Tavistock Clinic in England where she began researching attachments between mothers and infants. Ainsworth is most known for her "Strange Situation" experiment which observed how children reacted to their mother briefly leaving an unfamiliar room. Based on her research, she identified three main attachment styles in children: secure, anxious-avoidant, and anxious-resistant.

3. Attachment Theory
Mary Ainsworth “attachment theory” was based of the
behavior children exhibited when the caregiver does not
provide the necessary care or is absent. The absence
from the caregiver makes the child insecure.
Furthermore, the lack of a stable mother or caregiver
causes the child to experiences emotional effects.
Ainsworth believed that the attachment between the
caregiver formed a secure base for children to explore.
In addition to, caregivers being sensitive to children
signals of need and patterns. Forming these
securements now makes for a successful adulthood.
This lead to her procedure called “The Strange Situation
Experiment”. This experiment supported her theory by
testing the amount of stress children displayed when a
stranger was near. This lead to researches identifying
four different attachment children have based on their
securement with their caregiver.
