Handedness and writing performance

The present study investigated possible differences in left- and right-handers' writing performance. An equal number of left- and right-handed Greek children (N = 182) ages 7 to 12 years were examined using the Greek adaptation of Luria-Nebraska's neuropsychological battery in spontaneous writing, copying, and writing to dictation. Analysis showed a significant effect of age in writing performance and writing speed, while handedness was not significantly related to writing performance or writing speed. However, the incidence of right-handers was slightly higher among proficient writers, whereas the left-handers were clearly overrepresented among poor writers. The results are discussed on the grounds of neuropathological as well as hormonal-developmental theories of handedness.
