“…Historically, dyslexia was thought to be a visual processing disorder ("word blindness"; Orton, 1937). A deficit in phonological processing is the current dominant theory in developmental and educational research (Bishop, Snowling, & Blakemore, 2007;Shaywitz, 1998;Vellutino, Fletcher, Snowling, & Scanlon, 2004) though rapid-naming (visual recognition of words at speed), which was originally proposed as a causal factor by Denckla & Rudel (1976) is still routinely tested in diagnosis (Grant, 2009;McLoughlin & Doyle, 2013;McLoughlin & Leather, 2013) and therefore in practice, the double-deficit hypothesis (Wolf & Bowers, 1999 -meaning both difficulties in rapid naming and the accurate decoding of sounds) is still used to define and determine individual cases. Further to phonological deficit theory, neuropsychological researchers have highlighted the phonological short-term component of 'working memory' (our capcity to hold information in our attention long enough to manipulate it, as the primary neural mechanism leading to phonological processing difficulties, which in turn result in delayed literacy acquisition (Jeffries & Everatt, 2004;Smith-Spark, Fisk, Fawcett, & Nicolson, 2003;Swanson & Siegel, 2001;Torgesen, 2001).…”
