Abstract
Hand is the well established and studied marker of brain lateralisation. 90% of world population is right handed while 10% is left handed. There individuals with dominant right or left hand differ in certain behavioural and habitual patterns which can be observed in terms of preferential use of eye, ear and foot. Hence in this study an attempt was made to determine the association between hand preference with the preference to eye, ear and foot. This study included 300 participants (150 right handed and 150 left handed). The handedness, footedness, eyedness and earedness were determined by Edinburg Handedness Inventory, Chapman Foot preference Inventory, Miles test and Lateral Preference Inventory respectively. It was found that hand preference was significantly associated with foot preference and eye preference but not with ear preference. In case of gender, significant association was observed only in case of foot preference.
Key words: Eye, ear, hand, foot, gender, association
