+ Tested a range of variables 

+ Culture was varied across conditions so comparisons could be made

- Cultural conditions were not manipulated so we cannot conclude that culture caused the observed differences

- Moral judgements were based on the way that the children reacted to stories, may not reflect everyday moral judgements

Valifity and reliability

+ Procedures were simple and easy to standardise, increasing reliability

+ Results could be checked by someone else…
