Question

Quizplus · Accepted Answer

Research has shown that left-handers are more likely than right-handers to have a more equal distribution of language processing between the two hemispheres of the brain. This means that left-handers may not necessarily process speech primarily in their left hemisphere, unlike most right-handers. A, B, and D are incorrect as research has not shown any significant gender differences in left-handedness, the size of the corpus callosum is dependent on several factors and not strongly related to handedness, and there is no conclusive evidence that left-handers are generally less competent in mathematics.
