strange situation experiment carried out by mary and measures reactions to reunions and separation to caregivers
the strange situation was devised in the 1970s and was a standardised procedure to observe attachment security
applies to infants between the age of nine and eighteen months
Ainsworth and Bell (1970) conducted a controlled observation recording the reactions of a child and mother (caregiver), who were introduced to a strange room with toys.
100middle classamerican infants and their families participated
The room was set up with a clear 9 x 9-foot floor space divided into 16 squares for recording location and movement.
The child is observed playing for 20 minutes while caregivers and strangers enter and leave the room, recreating the flow of the familiar and unfamiliar presence in most children’s lives.
Ainsworth & Bell observed from the other side of a one-way mirror, so the children did not know they were being observed.
marked behavuours every 15 seconds
The observers noted the behavior displayed during 15-second intervals and scored the behavior for intensity on a scale of 1 to 7.
observations were in 5 groups:
proximity and contact seeking
contact maintaining
avoidance of promixity and contact
resistance to contact and comfort
search behaviour
obervers rated behaviours every 15 seconds on a scale to 7
they were generally securely attached meaning they displayed certain characteristics:
confidently explore environments when their caregiver is present
experience moderate distress when left without their caregiver
show moderate stranger anxiety
seek comfort and are easily soothed by their caregiver
