It is widely known that language functions in our brains are lateralized to the left hemisphere and spatial recognition functions are lateralized to the right hemisphere. It is also known that handedness is closely related to the lateralization of brain functions. However, at what point in the brain‘s development the lateralization of brain functions takesplace is still disputed. This study sought to find differences in linguistic and spatial abilities between left-handed and right-handed children, and provide objective data on the relationship between the handedness and the brain lateralization. 19 left-handed children and 20 right-handed children aged 5 were chosen through questionnaire for this study and the K-WPPSI simple intelligence test was used to check the homogeneity of two groups. The results showed that the differences inlinguistic and spatial ability between left and right-handed children were not statistically significant.
