Lateral preferences for hand, foot and eye, and their lack of association with scholastic achievement, in 4143 Chinese

A questionnaire survey was conducted among Chinese students divided between a grade-school sample and a university sample. Social pressure for right-handed writing and eating was effective, but showed limited transfer influence on other activities. Details of the handedness distribution varied with particular item combinations, but the general features of the distribution showed the same characteristics found in Caucasian samples. Distributions of lateral preferences in foot and eye uses, as well as the inter-correlations among hand, foot and eye preferences, were also comparable with Western results. No difference was obtained between the grade-school sample and the university sample, indicating a lack of association between lateral preferences and intelligence in the non-clinical population.
