Two studies involving stereotypic hand gazing revealed that: (1) a dramatically increased therapy program substantially reduced a 35.4 month-old boy's hand gazing and augmented his toy manipulation skills; and (2) both glasses and toys effectively reduced hand gazing by two visually impaired 30.3 and 17.9 month-old children.
