“…They also added that requiring verbal processing in the task as opposed to arithmetic processing (e.g., operation span task) can better distinguish between skilled and less skilled readers. Waters and Caplan's (1996) scoring system was later adopted by a few studies (e.g., Leeser, 2007;Shin, Dronjic, & Park, 2019). However, a more common system is the one that includes a storage task and a processing task without taking reaction times into account (e.g., Chun & Payne, 2004;Joh, 2015;Kozan, Erçetin, & Richardson, 2015;Osamu, 2006), and quite a number of studies still used the original method that relies only on the storage component (e.g., Bailer, 2011;Chun & Payne, 2004;Shibasaki, Tokimoto, Ono, Inuoe, & Tamaoka, 2015).…”
