The cognate advantage in bilingual children varies in strength across groups and individuals, in particular on receptive measures (e.g. picture-identification). This variation may be due to children's developing ability to benefit from cognates in such tasks, yet longitudinal studies of this phenomenon, especially with older children, are rare.…

Pictures were drawn to represent the different stages of distributive justice for a given dilemma and the DJS was scored by selecting the child's preferred stage via the picture comparisons for each…
