Abstract

Objective: The aim of this study was to investigate working memory function in ADHD and ADD children.
Methods: In this study, 25 subjects (ADD=12 / ADHD=13) were selected by SNAP4 Scales. ERPs were measured while subjects answered visual working memory task. T test and Umanvitni was used for analyzing the behavioral data and Repeated Measurement of Variance (RANOVA) was used to analyze the ERPs data.
Results: We didn’t find any significant differences between ADD and ADHD subjects in behavioral data (comisson, omission and reaction time) and P300 component.
Conclusion: The finding confirms previous researches that suggested, there weren’t any differences between ADD and ADHD children in cognitive processing. It seem working memory in ADD children performs as same as ADHD children.
