From this and other research, we now know that there are many lateralized functions. In general, the left hemisphere is specialized for processing language and producing speech, carrying out sequential processing of information, focusing attention, and inhibiting negative emotions.
What functions are lateralized to the right hemisphere?
Language functions such as grammar, vocabulary and literal meaning are typically lateralized to the left hemisphere, especially in right-handed individuals. While language production is left-lateralized in up to 90% of right-handers, it is more bilateral, or even right-lateralized, in approximately 50% of left-handers.
What is lateralization of hemisphere function?
Lateralization of the brain hemispheres refers to a functional dominance of one hemisphere over the other, in which one is more responsible or entirely responsible for control of a function in comparison to the other.
