Visagraph II와 DEM검사의 상관성 분석

Purpose: To investigate whether DEM test were able to assess reading ability. Methods: For 246 elementary(4-6 grade) children, Visagraph II and DEM tests were performed and investigated whether horizontal, vertical, number of error and horizontal/Vertical (H/V ratio) of DEM tests were correlated with average fixation, regression, duration and reading rate of Visagraph II, respectively. Results: Fixation, duration and reading rate of Visagraph II were significantly correlated with adjusted vertical time, and regression were correlated with adjusted horizontal and vertical time. Conclusions: Adjusted horizontal time and H/V ratio which were important factors of DEM test were not correlated with reading rate of Visagraph II. Therefore DEM test need further research of validity for assessing reading ability.
