Language functions such as grammar, vocabulary and literal meaning are typically lateralized to the left hemisphere, especially in right-handed individuals. [7] 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. [8]
As suggested by Kimura (1975, 1982), left hemisphere speech lateralization might be based upon a preference for movement sequences as demonstrated by American Sign Language (ASL) studies. Since ASL requires intricate hand movements for language communication , it was proposed that skilled hand motions and speech require sequences of action over ...
The left hemisphere is associated with language and calculations, while the right hemisphere is more closely associated with visual-spatial recognition and facial recognition. This lateralization of brain function results in some specialized regions being only present in a certain hemisphere or being dominant in one hemisphere versus the other ...

Language areas are represented unilaterally in the human brain. [3] In around 95% of right-handers, these brain areas are often located on the left hemisphere, however the proportion reduces in left handers down to around 70%. [2] Therefore 7 in every 100 individuals is right-hemisphered for language and left-hand dominant. [4]
The development of dyslexia has been explicitly highlighted in those who have a specific cerebral lateralisation pattern, which have shown difficulties in language processing. Typically, the left hemisphere of the brain is dominant in language processing; however, individuals with dyslexia may have an underdeveloped or functionally impaired ...
In both types of languages, they are affected by damage to the left hemisphere of the brain rather than the right -usually dealing with the arts. There are obvious patterns for utilizing and processing language. In sign language, Broca’s area is activated while processing sign language employs Wernicke’s area similar to that of spoken language.
Verbal memory is a term used in cognitive psychology which refers to memory of words and other abstractions involving language. A variety of tests is used to test verbal memory, including learning lists or pairs of words, or recalling a story after it has been told.
