“…Studies that examine 2D to 3D transfer of learning over long retention intervals will provide us with important practical and educational information about learning across these different media platforms during toddlerhood. At the same time, these findings provide us with new theoretical information, garnered from highly controlled manipulations, about the developmental course of transfer of learning (DeLoache, Simcock & Marzolf, 2004; Durkin & Blades, 2009; Keates, Graham, Ganea, under review) and the development of representational flexibility (Hayne, 2006). Taking Barnett and Ceci’s (2002) taxonomy of transfer framework into consideration, the present study of transfer of learning from 2D sources allows for specific manipulation of modality (from 2D to 3D), social (media model v experimenter), and temporal context (immediate v. delay).…”
