Ainsworth's Strange Situation

Ainsworth et al devised an assessment technique called the strange situation in order to investigate how attachments might vary between children. She carried out an observational lab study and developed an experimental procedure to observe the variety of attachment forms exhibited between mothers and infants. Ainsworth’s ‘strange situation’ was conducted by observing the behaviour of the infant in a series of 3-minute episodes as follows 1.) Parent and infant alone in the room 2.) Stranger joins parent and infant 3.) Parent leaves infant and stranger 4.) Parent returns and stranger leaves 5.) Parent leaves; infant left alone and procedure carries on until child is distressed. Ainsworth identified attachment types in the strange situation and assorted the children’s behaviours into three categories 1.) Anxious-avoidant: ignores mother, comforted by stranger 2.) Secure: Happy in mothers presence, distressed when she leaves and 3.) Anxious-resistant: Resists stranger and mother. Main et al explored the relationship between mothers behaviours and type of attachment and found that mothers who themselves had satisfactory attachment experiences would have children who were securely attached. Ainsworth’s procedure has been replicated many times to see whether the classifications show good reliability over time and the category percentages are similar across all cultures. However, Ainsworth failed to show good test-retest reliability in her replications of the strange situation classification, other studies have found a fairly stable classification over time, certainly with secure children. Wartner et al found that 78% of children between the ages of 1 and 6 in Germany were classified in ainsworths categories – showing that the strange situation classification has consistent results between the type of attachment at infancy and relationships in later life, therefore we
