weaknesses of the cross cultural meta study
study was not globally representative
Africa, South America, and Eastern European socialist countries were not represented
- 18 out of the 32 studies were american - makes the results misleading
ethnocentric behavioural categories
- the original categories used worldwide were originally based on ainsworths observation of middle-class american infants
- so when researchers carry this study out on non americans, their data is being compared to american standards eg: being independant is highly valued in germany but is negatively viewed as 'avoidant' in usa
lack of standardised procedures throughout the diff studies
- possible that the way of categorising was diff in diff studies eg, subjective nature of defining distress levels
- the studies did not all conduct exactly the same procedures eg takahashi who removed the child alone stage from 90% of the studies which alters the findings and makes it unable to be compared
number of participants in the studies
- some studies had a very small sample size which brings reliability into question
