“…However, it is unclear whether this is the effect of age or of literacy, because literate children are typically older than preliterate ones (Karmiloff-Smith, Grant, Sims, Jones, & Cuckle, 1996). A recurrent finding in adults is that illiterate adults have more difficulty than literate adults segmenting utterances into word units, supporting the suggestion that literacy plays a role independent of that of age in the development of lexical segmentation (Gombert, 1994; Kurvers, 2015; Kurvers & Uri, 2006; Kurvers et al, 2009; Veldhuis & Kurvers, 2012). However, there are many challenges involved in comparing literate and illiterate adults and in assessing language processing in illiterate populations, which make it hard to isolate the effect of literacy on lexical segmentation.…”
