Ainsworth's strange situation (1970)- types of attachment

What types of experiment is this experiment?

a controlled observation

Episodes of strange situation: what happens before the episodes?

Caregiver and baby enter an unfamiliar playroom

Episodes of strange situation: episode one

Baby is encouraged to explore

• tests: exploration and secure base

Episodes of strange situation: episode two

a stranger comes in, talks to the caregiver and approaches the baby

• tests: stranger anxiety

Episodes of strange situation: episode three 

caregiver leaves the stranger and baby together

• tests: separation and stranger anxiety

Episodes of strange situation: episode four

caregiver returns and the stranger leaves

• tests: reunion behaviour and exploration/ secure base

Episodes of strange situation: episode five

caregiver leaves baby alone

• tests: separation anxiety

Episodes of strange situation: episode six

stranger returns

tests: stranger anxiety

Episodes of strange situation: episode seven

caregiver returns reuniting with the baby

tests: reunion behaviour

What behaviours are looked for to judge attachment?

• Proximity seeking

• Exploration and secure base behaviour

• Stranger anxiety

• Separation anxiety

• Response to reunion

Findings: What are the types of attachment?

• insecure- avoidant (type A)

• Secure attachment (type B

• Insecure- resistant (Type C)

What is Insecure- avoidant (Type A)?

willing to explore, had low stranger anxiety, were indifferent to anxiety and avoided contact when parent returned.

What is secure attachment (Type B)?

willing to explore, had high stranger anxiety, were easy to soothe and were enthusiastic at the return of their mother.

What is Insecure resistant (Type C)?

unwilling to explore, had high stranger anxiety, were distressed at separation but sought and rejected contact when parent returned.

What are the characteristics of the main attachment types with respect to the stranger situation findings?

What did Ainsworth conclude about the sensitivity of the mother?

• attachment differences depended upon the sensitivity of the mother (i.e. how well the mother could read her infant’s feelings and moods)

• sensitive mothers generally had infants who were securely attached

• less sensitive and less responsive mothers (i.e. those who ignored their infant or were impatient with them) had babies who were more likely to be insecurely attached a baby’s attachment does seem to be affected to some extent by the quality and sensitivity of the caregiver

Evaluation: good predictive validity

P – A strength is there is a predictive validity of attachment types in the Strange Situation.

E – Attachment type predicts later development. For example, secure babies typically have greater success at school and more lasting romantic relationships.

E – In contrast, insecure-resistant attachment is associated with the worst outcomes eg bullying (Kokkino) and adult mental health problems (Ward et al).

L – This means that there is evidence for the validity of the concept because it can explain future outcomes.

Evaluation: good reliability

P – A further strength is that the Strange Situation shows very good inter-rater reliability.

E – Different observers watching the same children generally agree on attachment type. Bick et al found 94% agreement in one team.

E – This may be because the Strange Situation takes place under controlled conditions and because the behavioural categories are easy to observe.

L – This means that we can be confident that the attachment type of an infant identified in the Strange Situation does not just depend on who is observing them hence its strong reliability

Evaluation: culture bound

P – A limitation is that the Strange Situation may be a culture-bound test.

E – The test might not have the same meaning in countries outside Western Europe and the USA.

E – Cultural differences in children’s experiences mean they respond differently. Also, caregivers from different cultures behave differently.

L – Takahashi notes that Japanese mothers are rarely separated from infants thus the infants show high levels of anxiety. This means that the Strange Situation may not be a valid test of attachment across a variety of cultures.
