Laterality research also explains cerebral dominance that gets reflected through peripheral measures such as preference for usage of hand, foot, eye, ear, and face. For example, the prevalence of left-handedness in India is reportedly as low as 3.2% (recent findings have reported 6.78% left-handers in the population). As far as foot preference is concerned, majority of the humans use the right foot for mobilization and the left foot for postural stability. Researchers have even reported difference in the preferential usage of these peripheral indices between normal and clinical population. For instance, the right hemisphere dominance in the autistic individuals gets reflected in their superiority at spatial tasks and face recognition. Healthy children show left ear preference for music and right ear preference for verbal stimuli whereas autistic children show left ear preference for both the types of stimuli.
