摘要：AbstractThis empirical study reports on the issue of L1 lexicalization. Participants were 74 juniors at the Islamic Azad University, Roudehen Branch. The investigation pursued (i) the pedagogical impact of the provided treatments (ii) the psycholinguistic importance of the issue of L1 lexicalization. The results of the independentt-test indicated a significant difference between the two groups dealing with both sets of words. The pairedt-test analysis demonstrated a significant difference between the gain scores in favour of lexicalized items in the interventionist group. However, no significant difference was found with respect to the gain scores in the non-interventionist group.
