Quizplus · Accepted Answer

Cultural factors can play a role in determining hand preference. For example, some cultures promote the use of the right hand for eating and the left hand for hygiene purposes. Heredity may also play a role, but it is not the sole determinant of hand preference. Hand preference can be observed in infants as young as a few months old, but it becomes more pronounced as children grow and develop.
