This study investigated the effects of three vocabulary development strategies of keyword method, thematic clustering and developing morphological awareness on the Iranian EFL learners’ vocabulary repertoire. Adopting a quasi-experimental design, sixty high-intermediate to advanced Iranian EFL learners were randomly assigned to three experimental groups and partook six online sessions of vocabulary instruction during a week. Using a pre-test and three post-tests, the vocabulary repertoire of the subjects was quantified. The pre-test was administered a week before the commencement of the treatment sessions; the first post-test was administered immediately after each treatment; the second post-test was held 24 hours after each treatment and the third post-test was held one week after the end of the treatment sessions. Paribakht and Wesche (1993) model of measuring vocabulary enhancement was used to quantify the vocabulary repertoire of the subjects. Split-plot ANOVA test revealed that the subjects in the keyword group outperformed the subjects in the other two groups in all the three post-tests. Moreover, it was revealed that the thematic clustering group outperformed the developing morphological awareness group. The findings of this research may have pedagogical implications for English teachers, learners and material developers.

Robinson’s Cognition Hypothesis and Skehan’s Limited Attentional Capacity Model provide the major impetus for this study. The present article reports the findings of a between-subject factorial experimental research study which explored 1) the effects of increased cognitive task complexity, manipulated through the intentional reasoning demands and number of elements on the lexical and syntactic complexity, accuracy, and fluency (CAF) of EFL writers’ productions; and 2) the joint effects of cognitive task complexity factor and learners’ language learning aptitude (Low vs. High) on the written output. Firstly, we gave Carroll and Sapon’s Modern Language Aptitude Test (MLAT) to 226 participants and then did a random stratification of the low- and high- aptitude learners into three groups. The participants received letter writing tasks with different cognitive complexity levels (low, medium, and high). The findings indicated that increasing cognitive task complexity resulted in significantly higher lexical and syntactic complexity and lower fluency, whereas no significant effect was found on writing accuracy. Moreover, the statistical results revealed no significant interaction effect between task complexity factors and learners’ language aptitude. With regard to the first objective of the study, the findings supported the predictions of Cognition Hypothesis while it is not the case in relation to the second objective of the study.
