Lateral preferences among indian school children.
In the first study, 718 children from India, aged 4 to 11 years, were observed for their hand preference for ten common unimanual activities. The prevalence of left-handedness was found to be only 3.2 percent, i.e. one-third of that (9.6%) observed in a French study using a similar procedure. The degree (weak to strong) but not the direction of hand preference was found to be related to the children's age, with stronger preference among older children. The factor structure of handedness items was similar in France and India. In the second study, 400 schoolchildren from India, aged 6 to 18 years, were examined for handedness, footedness, eyedness, use of hand in space, and absolute and relative hand skill assessed by a peg-moving task and a dot-filling task. Prevalence of left-handedness was 4.2%. A sex difference was observed for handedness, footedness, use of hand in space. and relative hand skill, with higher proportions of right preferences and higher degree of lateralization (i.e., relative between hands asymmetry) in females. The degree of hand skill asymmetry increased with age. These results are discussed in relation to findings from previous studies in other countries using similar procedures.
