The present study aimed to investigate the effects of three common techniques of input enhancement, namely, visual input enhancement, semantic input enhancement, and input flooding on female Iranian EFL learners' comprehension and production of lexical collocations. The participants were 80 learners, aged between 16 and 40, studying English in two private institutes in Karaj. To begin with, the participants were given an ECCE test of general language proficiency to determine their proficiency level. After taking a pretest, comprising 110 collocations items, the participants (in three experimental groups and one comparison group) received 10 reading passages over 10 sessions in which lexical collocations were presented in the above-mentioned conditions. At the end of the experimental period, the participants took two posttests of comprehension and production of collocations. Two One-way ANOVA procedures were used to analyze the obtained data, and the results showed no significant differences among the effects of the three input enhancement techniques on the comprehension and production of lexical collocations.
