Abstract

Memorizing the Qur’an is one of the working memory activities as several factors influence the activity of memorizing the Qur’an. However, some argue that memorizing the Qur’an would rather be influenced by the efforts made to maintain perseverance, attention, and mood than the level of individual intelligence. The purpose of this study was to examine the predictive role of the variables in working memory among the Qur’an memorizer, who is called hafidz. This study involved 169 participants from two different universities that hold Tahfidz Qur’an between the age of 17 and 25 were selected from. The participants were asked to fill out four questionnaires (Mood, Emotional Reactivity, Effortful Control, and Working Memory) and paper-and-pencil based IQ test. Based on multiple regression analysis performed, this study found that effortful control was the most significant predictor to working memory, attention and executive within working memory. Effortful attention likewise predicted working memory, attention and execution within working memory. In addition, this study showed that, except emotional reactivity, the other independent variables were the predictors of working memory or its dimensions.

Keywords: Effortful control, IQ, Mood, Emotional reactivity, Working memory, Level of intelligence.
