Kamawar, D. & Olson, D. R. (2010). Children’s understanding of referentially opaque contexts: The role of metarepresentational and metalinguistic knowledge. Journal of Cognition and Development, 10, 285-305.
We investigated whether children’s ability to deal with referentially opaque contexts could be predicted by both metarepresentational ability (false-belief understanding) and metalinguistic awareness (the ability to compare and evaluate statements containing referring expressions). Five- to seven-year-olds completed opacity, false-belief, metalinguistic awareness, digit-span and vocabulary measures. Hierarchical regressions indicated that even after the variability from age, vocabulary and digit span was taken into account, metarepresentational ability and metalinguistic awareness still significantly and independently explained some variability in referential opacity performance. These results are taken as support for the view that both metarepresentational ability and metalinguistic awareness are necessary in order to deal with referentially opaque contexts.
