-aim = to see how infants behave under different conditions (mild stress). Wanted to assess their attachment style.
-procedures = lab setting, controlled observation, child & mother observed interacting with different scenarios (7) - done using a one way mirror. The behaviours observed were: exploration, proximity seeking, stranger anxiety, separation anxiety and reunion behaviour.
-controlled setting. Can see cause & effect - increased internal validity. HOWEVER, decreased ecological validity so cannot be applied to real-life attachment.
-application. Parents can look for specific behaviours their children do. HOWEVER, this is socially sensitive as parents could think they did something wrong. People are not protected from psychological harm.
Weakness(es):
-cultural bias. Research was developed in Britain and conducted on American ppts = individualistic cultures, collectivist cultures not included. Decreases the generalisability.
-mothers were from different educational and professional backgrounds.
-attachment may change based on culture because of factors like how much the mother works.
Simonelli et al - AO3:
Strength(s):
-supports the strange situation as findings are similar.
Weakness(es):
-cultural bias as only Italian babies were used.
Jin et al (2012):
-compared attachment types in Korea and other countries.
-used 87 infants using the same procedure as the strange situation.
-found that in Korea the percentage of secure and insecure resistant attachment are similar to those of the strange situation. Only one infant was insecure avoidant.
-found that Korean mothers approached their infant faster on reunion than those in the strange situation
-maternal sensitivity is linked to attachment.
Jin et al - AO3:
Strength(s):
-supports the strange situation
- is valid and reliable.
Weakness(es):
-the infants could not give informed consent.
cultural variations - AO3:
Strength(s):
-indigenous researchers. Researchers from the same background as participants so they understand the behaviours presented. Increases the validity.
Weakness(es):
-imposed etic - same research design is being used in different cultures despite the cultures being different. Findings into attachment cannot be generalised to other cultures.
-confounding variables - different cultures have different methodologies and characteristics. Research into attachment lacks population validity because of this and therefore cannot be applied across cultures.
