Effects of textual enhancement on English as a foreign language learners' anaphor resolution performance and reading comprehension in Taiwan

Successful anaphor comprehension in reading is related to the explicitness of the antecedent–anaphor relation. It mirrors one of the purposes of textual enhancement (TE), which is that it raises learners' awareness of linguistic forms by enhancing the salience of input. Therefore, learners notice the enhanced form and discover the rule or relationship after they have become relatively explicit. This study investigates the effects of TE on second language learners' anaphor resolution performance and reading comprehension, to reveal the interaction among learners' comprehension, anaphor performance and noticing. Sixty EFL learners in Taiwan were divided into the control and TE groups. Participants' posttest responses were compared with respect to their anaphor resolution performance and their reading comprehension degree. The results showed that the TE group had better anaphor resolution performance, and participants' form processing did not impede their reading comprehension. These findings are discussed with both theoretical and pedagogical implications.
