Ambidexterity is defined as the ability to use both hands equally well, an unusual skill in the normal population. The term mixed dominance has been used to describe a confusion or delay in the development of hand dominance in persons with disabilities. When does hand dominance emerge in normal development?

According to Dr. Arnold Gesell, the developmental progression in the first year begins with use of one hand, then the other, then alternating hands, and then using both hands together, first symmetrically (about 4 months), then one assisting the other (about 1 year). Tasks requiring each hand to perform different skilled movements develop during the preschool years and beyond. A majority of children show a preference by age 3 and most by school age, but Dr. Gesell wrote that hand dominance doesn't become well integrated in some normal children until eight or nine years of age (Gesell & Ames, 1947). It is also true that some adults demonstrate skillful ambidexterity, especially in sports. What affects hand dominance more: genetic or environmental factors?
