A cross-cultural study of cognitive development.

This Monograph summarizes a comparative study of recall memory among children from two Guatemalan towns and one American city. The age interval of greatest improvement in serial recall of pictures, words and orientations of dolls varied across settings by as much as 4-6 years, but performance improved with age in all communities. It was suggested that the activation of varied strategies to aid recall memory emerged in all children during the preadolescent years, but environmental factors, as yet unspecified, determined both the slope of the growth function and its asymptotic level.
