“…Typically, the acquisition of spelling-to-sound knowledge is measured using nonword reading performance because decoding nonwords must be done by the application of spelling-to-sound rules. Early comparisons of monolingual studies reveal that while children who learn consistent orthographies perform at between 80% and 89% on nonword reading tasks, where percent correct is determined according to whether the regular or most dominant pronunciation of the graphemes in the nonword is produced (Cossu, Gugliotta, & Marshall, 1995;Porpodas, Pantelis, & Hantziou, 1990;Sprenger-Charolles, Siegel, & Bonnet, 1998), English children lag behind at 45% (Frith, Wimmer, & Landerl, 1998). Cross-linguistic studies, where tighter control over items and subjects can be exerted, show similar results, with English children performing at between 12% and 51% correct, compared with children that learn more consistent non-English orthographies performing typically above 90% correct (Ellis & Hooper, 2001;Frith et al, 1998;Goswami, Gombert, & de Barrera, 1998;Seymour et al, 2003).…”
