 As early as 3 to 4 months of age, infants show the beginning requisites of joint attention, by looking in the general direction as adults; however, they are not consistently able to find the shared point of reference.At 10 months, this accuracy improves, and infants are also more discerning in their response to joint attention.For example, at this age, a 10-month-old will not look in the same direction as an adult if that adult's eyes are closed, a mistake that younger children make.
