Who is more expressive during child-robot interaction: Pakistani or Dutch children?

In this study we have tried to determine if the cultural background of children has an influence on how they interact with robots. Children of different age groups and cultures played a card guessing game with a robot (iCat). By using perception tests to evaluate the children's emotional response it was revealed that children from South Asia (Pakistani) were much more expressive than European children (Dutch) and younger children were more expressive than the older ones in the context of child robot interaction.
