“…Research, with varying degrees of confidence, has reported beneficial effects of ER on various aspects of L2 ability, such as gains in reading speed and reading comprehension (Bell, 2001;He, 2014, Mermestein, 2014Suk, 2017;Tanaka & Stapleton, 2007), silent reading rate (Taguchi, Takayasu-Maass, & Gorsuch 2004), vocabulary knowledge (Tiryaki & Tütüniş, 2012;Wang, 2013), reading comprehension and vocabulary knowledge (Chen, Chen, Chen & Wey, 2013), grammatical competence (Sheu, 2003), and general English language proficiency (Al'zubi, 2014;Elley & Mangubhai, 1983;Yamashita, 2008), and development of writing skill (Al-Mansour & Al-Shorman, 2014;Kirin, 2010;Mermelstein, 2015). The benefits of ER is not limited with linguistic aspects alone, it is also found to boost students' L2 reading motivation (Fujito & Noro, 2009;Guo, 2012), L2 reading attitude (Atay, 2004;Ro & Park, 2016;Salameh, 2017;Yamashita, 2013), L2 reading self-efficacy (Burrows, 2012;Lake, 2014;Raissi & Roustaei, 2013), learner autonomy (Channuan & Wasanasomsithi, 2012;Mede, Incecay, & V. Incecay, 2013) and to lower L2 reading anxiety (Ro, 2013).…”
