“…It also shows that, despite significant 8 delays in learning and transfer of information from picture books, children from a pictorially sparse culture begin to treat pictures referentially, as a source of information about the world, by the end of their 3rd year of life. There have been a variety of proposals regarding the particular types of experiences that may be necessary for the early development of pictorial understanding during infancy, ranging from early exposure to two-dimensional images (e.g., Bovet & Vauclair, 2000;DeLoache et al, 1979;Deregowski, 1989), independent exploration of pictures (e.g., DeLoache, 1991;DeLoache et al, 1998;Fletcher & Sabo, 2006;Murphy, 1978), cultural experiences with other people using pictures and other symbols to communicate information about the world (e.g., Callaghan et al, 2011;Callaghan & Rankin, 2002;DeLoache & Burns, 1994;Gelman et al, 2005), or some combination of these factors. Future cross-cultural research examining the specific skills involved in the development of referential understanding of pictures and the type of experiences that affect these skills could reveal important information about mechanisms underlying symbolic development.…”
