“…Overall, pronunciation is better predicted by the application of onset and rime sized correspondences than by the application of grapheme-phoneme correspondences (Vousden, 2008), but many more onset-rime units are required to achieve accurate pronunciation (Solity & Vousden, 2009;Vousden, 2008), thereby increasing the complexity of the solution to be adopted by the cognitive system, an issue that has received little consideration. For example, Solity and Vousden (2009) showed that the amount of monosyllabic adult text that could be accurately decoded by applying 64 grapheme-phoneme correspondences would require the application of 63 onset and 471 rime correspondences. Following the literature that found a developmental progression from large to small unit phonological awareness, and a number of studies that suggested training children about onset and rime could be beneficial for reading acquisition (Goswami, 1986;Wise, Olson, & Treiman, 1990), there emerged a large literature comparing different methods of instruction based on different unit sizes, from whole words (e.g., I. S. Brown & Felton, 1990) and rimes (e.g., Greaney, Tunmer, & Chapman, 1997), to graphemes (e.g., Stuart, 1999).…”
