Mary Ainsworth is known best for her elaboration work of John Bowlby and his attachment theory. She developed a procedure for the observation and assessing the quality of attachment in relationships between the child and a caregiver. The procedure was called the ‘Strange Situation’. In the experiment the child was observed playing for twenty minutes. Meanwhile the caregivers and strangers enter and leave the room. This recreated the flow of the familiar and unfamiliar persons in the lives of most children Despite her procedure, it has been criticized as the the twenty minutes time-frame for the procedure was too short and too many variables could come into play.
