The Present study investigated how personality type, extrovert and introvert, responded to dialogic feedback targeting the simple past tense. Previous researches have not particularly investigated the relation between dialogic feedback and personality types in Iranian EFL context. To fill this gap, we selected above question in order to shed light on the contribution of extrovert and introvert personalities through dialogic addressing simple past tense. This study was conducted through quantitative method and the population of the present study was all intermediate and advanced EFL learners in a private institute of Babol. To classify learners based on personality traits (i.e., extroversion and introversion), Eysenck personality questionnaire (EPQ) was applied. 19 learners participated in this study including 14 extroverts and 5 introverts’ learners. The data collection was done through pre-test and post-test. In pre-test, learners had to narrate three different stories and they received dialogic feedback from their teacher whenever they had wrong past copulas production, based on Aljaafreh and lantolf regulatory scales from the most implicit one to the most explicit one by considering learners’ zone of proximal development (ZPD) according to sociocultural theory. However, in post-test, they had to retell the first story without receiving any dialogic feedback. Learners’ productions were transcribed after recording, and their performances were analyzed through obligatory occasion analysis (Brown 1973). The finding of this study show that introverts performed better than extroverts in post-test story telling.
