Lateralization for Writing and Handedess: A Study Using Functional Transcranial Doppler Ultrasonography

This study examined how handedness affects cerebral lateralization for written language. Using ultrasonography, left-handers (n=30) and right-handers (n=30) completed oral and written language tasks. Both groups showed left-hemispheric dominance, though there was insufficient evidence for a between-groups difference (BF₁₀=0.4), highlighting the complexity of different language modalities in relation to handedness.
