“…More specifically, analysis of how student skill interacts with word regularity provides insight into the cognitive processes that underlie upper-primary students' performance on spelling-to-dictation tasks. There is considerable evidence from research with adult writers that spelling processes and their motor execution interact in single word production (Bertram, Tønnessen, Strömqvist, Hyönä, & Niemi, 2015;Delattre, Bonin, & Barry, 2006;Kandel & Perret, 2015;Lambert, Kandel, Fayol, & Espéret, 2007;Roux, McKeeff, Grosjacques, Afonso, & Kandel, 2013;Scaltritti, Arfé, Torrance, & Peressotti, 2016). Delattre et al, for example, found that in French (a deep orthography), both word frequency and orthographic regularity affected onset latency (time from stimulus presentation to output-onset, measured as onset of first pen stroke) and output duration (time from onset to word end, controlling for word length).…”
