Children's reaction times to verbal and nonverbal tachistoscopic stimuli exposed to the left and right visual hemifields.

Tachistoscopic tests of the left and right visual hemifields to identify three-letter words and simple geometric figures were administered to 64 children (32 boys, 32 girls) in the age group 7 to 8 yr. and in their second year of school. The results show no significant differences in visual perceptual threshold between the two hemifields for either of the two tests (three-letter words and simple geometric figures). The authors interpret the results as confirming a lesser and not definitely determined lateralization in children.
