Analysis of laterality and hand efficiency in a group of children aged from 5 to 10

Abstract

This study was aimed to compare left-arm and right-arm efficiency both in left-handed and right-handed children. Differences beteween non-dominant hands of left-handed and right-handed and coincidence between preferent arm and that of better performance were evaluated. The investigation was carried out on children aged 5 to 10 years. Maximal differences between dominant and non-dominant arm were detected for frquency in the efficiency test. Performance of the dominant arm in frequency, reaction time, force and manipulation, was better for right-handed that for left-handed. KEY WORDS: Laterality, Efficiency, Left-handed, Right-handed
