This paper reviews the literature on handedness in infants and reaching behavior in neonates and speculates on evolutionary reasons for the development of handedness. Modern studies have reliably detected handedness from the second half of the first year of life. One study found a preference for the right hand in unimanual tasks at 6.7 months.…

About 42 percent of the tested students were identified with the Monahan/DeYoung…
