Document Summary
Language is universal (every human society has a language except in extreme circumstances) and it is actually difficult to suppress language. Left hemisphere is not specialized for language at birth. Language shifts to left hemisphere with maturation. Left hemisphere is specialized for language right from birth. Erp (event related potentials which involves electrical activity through the brain) Fmri looks at blood flow throughout brain when language task are performed. Molfese presented syllables, words and nonspeech sounds to infants under ten months, children 4-11 and adults and recorded electrophysiological activity. Results the proportion of left dominance was the same in each age group. Right side was most active with non speech sounds. Speech stimuli are presented to two ears at the same time and then are asked to report what they heard. Information in right ear is processed by left hemisphere (contralateral pathways)
