Speech lateralization and handedness

WebAround 90% of humans prefer their right hand for unimanual actions and are left- hemisphere dominant for language functions; a pattern far from negligible. The phenomena of handedness and cerebral lateralization for language are presented along with the different theories that attempt to explain the presence of these functional asymmetries. WebFeb 19, 2024 · Studies have linked handedness with differences observed in language lateralization. More precisely, right-handed individuals are characterized by left hemisphere control of language, while left-handers have shown right hemisphere dominance in language or bilateral speech representation.
