Evaluation

• Large sample size

  -meta analysis of 32 studies and over 2,000 infants.

  -More representative and reduces the effect of anonymous results so overall conclusions about inter and intra cultural variations increases generalisability.

  -However, limited samples from some cultures. Countries may have sub-cultures which sample doesn't include so not representative of whole culture.
• Standardised

  -accurately compare attachment behaviours across different cultures without extraneous variables.
• Ethnocentric

  -Study was done in America with American infants. Behavioural categories created through American culture so may not be correct wen comparing against other cultures.
• Low Internal validity of the strange situation

  -Research into cultural variation uses strange situation to classify infant attachment.

  -Strange situation measures infant temperament, familiarity with strangers, relationship to mother.
