“…However, some specific cognitive skills have been shown to be reliable in predicting reading fluency (i.e., speed of accurate response to oral reading tasks). These predictors include letter knowledge (e.g., Georgiou, Torppa et al, 2012;Leppänen et al, 2008;Torppa et al, 2007;, phonological awareness (Al Oitaba & Fuchs, 2002;Mathes et al, 2005;Torppa et al, 2007;), vocabulary (Al Oitaba & Fuchs, 2006), verbal memory (Al Oitaba & Fuchs, 2006, autoregressor of reading (Hammil, 2004;Torppa et al, 2013) and RAN (Al Oitaba & Fuchs, 2002;Georgiou, Parrila & Papadopoulos, 2008;Lepola et al, 2005;Mathes et al, 2005;Scheltinga et al, 2010;Torppa et al, 2013); however, these predictors may be different for children with typically developing reading fluency and for those at risk for reading difficulties . According to several results from studies on transparent orthographies, RAN has emerged as the most effective predictor of reading fluency (Aarnoutse et al, 2005;Georgiou, Parrila, & Papadopoulos, 2008;Scheltinga et al, 2010;Torppa et al, 2007;.…”
