AP PSYCHOLOGY

Detailed explanation-1: -Left hemisphere dominance for language has been consistently confirmed in clinical and experimental settings and constitutes one of the main axioms of neurology and neuroscience.

Detailed explanation-2: -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.

Detailed explanation-3: -Recent studies have shown that in around 97% of people, language is represented in the left hemisphere. However, in about 19% of left-handed people, the areas responsible for language are in the right hemisphere and as many as 68% of them have some language abilities in both the left and the right hemispheres.

Detailed explanation-4: -There are several areas of the brain that play a critical role in speech and language. Broca’s area, located in the left hemisphere, is associated with speech production and articulation.

Detailed explanation-5: -Abstract. In most people the left hemisphere of the brain is dominant for language. Because of the increased incidence of atypical right-hemispheric language in left-handed neurological patients, a systematic association between handedness and dominance has long been suspected.
