Abstract
Background and Aim: Memory is the integral part of the learning process. There is strong correlation between academic achievements and components of short-term and working memory. The aim of the present study was to investigate the evolution of digit span memory in primary school-aged children. Materials and Methods: This comparative, cross-sectional study was conducted on 180 students from six grades of primary schools (30 students from each grade, 90 female and 90 male) selected by available sampling. They were evaluated by forward and backward digit span task. Two way ANOVA was used for data analysis. Results: There was significant difference between Forward and Backward Digit span scores across children in different grades of primary school (p<0.05). No meaningful relationship was found between gender and memory scores. Conclusion: The short term and working memory performances improve with age in primary school children, suggesting functional maturation of underlying cognitive processes and brain areas. Key Words: short term memory, working memory, student, Digit span.
