The Developmental Eye Movement (DEM) test is a clinical oculomotor test of a visual-verbal format which has been normalized and whose reliability and validity have been shown elsewhere in an English speaking population. In this paper, the authors provide normative data for a Spanish speaking population from ages 6 to 11 years. Also, a comparison of results for both languages is provided. The DEM test appears to be highly efficient and not linguistically related for all subjects involved in the study. Results in that age bracket are clinically the same. For age 6 years, although results are not similar (Spanish subjects are significantly slower), the ratio is similar in both groups. The DEM test appears to be reliable; its results could be used in any population regardless of the language.
