“…The effectiveness of reading as an important source of L2 vocabulary development has been questioned because a number of learner and text variables have been identified that aid, but more often impede, beginning L2 readers' word inferencing process. The four major factors that can have an impact on the outcome of inferencing are: (a) learners' knowledge about the linguistic properties of an unknown word (Bensoussan & Laufer, 1984;Haynes, 1993;Na & Nation, 1985), (b) context properties in which the unknown word appears (Bensoussan & Laufer, 1984;Haynes, 1993;Huckin & Bloch, 1993;Mondria & Wit-DeBoer, 1991), (c) the approach taken by the language learner to infer meaning (Chern, 1993;Lee & Wolf, 1997;Walker, 1983), and (d) cognitive processes that influence L2 readers' awareness of and attention to unfamiliar words (Coady, 1993(Coady, , 1997Ellis, 1994;Perry, 1993;Schmidt, 1995).…”
