Question

Quizplus · Accepted Answer

Handedness is strongest for complex skills requiring extensive training. Research suggests that handedness is more strongly determined by environmental factors, such as practice and training, rather than genetic factors. Thus, individuals are more likely to develop a strong preference for one hand when they engage in activities that require extensive training, such as playing a musical instrument or participating in sports.

Answer: None of the statements are accurate
 A, C, and D are all inaccurate statements regarding handedness. While there may be slight genetic influences on handedness, it is not a clear bias towards left-handedness. Left-handedness does not occur less frequently among people with mental illness, and there is no clear association between handedness and prenatal or birth difficulties.
