Question

Quizplus · Accepted Answer

Research has shown that for right-handed individuals, language is primarily housed in the left hemisphere of the brain. Left-handed individuals may have more variation in their language lateralization, with some having language primarily in the right hemisphere or even having more bilateral language processing. Option A is not entirely accurate as while there is a slightly higher chance of left-handed individuals having left-handed children, the majority of their offspring will still be right-handed. Option C is incorrect as studies have shown that the brains of left-handers tend to be less strongly lateralized than those of right-handers. Option D is also inaccurate as research has shown that prenatal events, such as differences in hormone exposure, are believed to play a role in determining handedness.
