The Interplay of Iranian EFL Learners’ Tolerance of Ambiguity and their Reading Performance Encountering Unknown Vocabularies: Taking their L۲ Reading Anxiety into Account

The interplay of Iranian EFL learners’ tolerance of ambiguity and their performance encountering unknown vocabularies in reading comprehension while considering their L۲ reading anxiety was investigated in this study. A sample of ۷۰ intermediate-level EFL learners from a language institute in Shiraz, Iran participated in the study. The Second Language Tolerance of Ambiguity Scale (SLTAS) and the Foreign Language Reading Anxiety Scale (FLRAS) were used to measure participants’ ambiguity tolerance and L۲ reading anxiety, respectively. To assess students’ performance in dealing with new words in reading comprehension, two vocabulary tests and two reading tests were given to them. The data were analyzed by both SPSS and PLS ۴ software using Pearson correlation and structural equation modeling (SEM). The findings revealed significant relationships between ambiguity tolerance and reading comprehension performance encountering unknown vocabularies, between L۲ reading anxiety and reading comprehension performance encountering unknown vocabularies, and between ambiguity tolerance and L۲ reading anxiety. Additionally, L۲ reading anxiety was found to play a significant mediating role in the relationship between ambiguity tolerance of Iranian language learners and their performance in dealing with unknown vocabularies in reading comprehension. Moreover, the study provides evidence that reading anxiety does not play a moderating and significant role in the relationship between ambiguity tolerance of Iranian language learners and their performance in dealing with unknown vocabularies in reading comprehension. The study suggests that ambiguity tolerance and L۲ reading anxiety are important factors that influence Iranian EFL learners’ performance encountering unknown vocabularies in reading comprehension. This study highlights the importance of fostering ambiguity tolerance and reducing L۲ reading anxiety in both language teaching and learning. In addition, it provides insights for syllabus designers to develop effective reading comprehension curricula for EFL learners.
