摘要:AbstractInverse-preference effects imply structures less favored by speakers are affected by structural priming. This study examines the role structural priming plays in the production of passive structures, a difficult and hence not favored structure among Iranian EFL learners. The 40 participants were placed in Experimental High-Proficiency, Experimental Mid-Proficiency, Control High-Proficiency, and Control Mid-Proficiency groups. Results of picture description sessions, analyzed by a two-way ANOVA showed that priming led to increased production of the target structure by experimental groups as compared with control groups. Furthermore, results indicated EFL level of proficiency made a significant difference in production of the target structure.
