Tactual exploration by normal infants.
Abstract
The age of onset for tactual exploration of the fingers, body (torso), knee, foot and penis by the fingers was determined in 100 normal infants. Exploration of the mouth, face, head, ears, nose and eyes was also studied by daily observations in the first three days of life in a second sample of 12 normal newborns, and the age of onset was recorded. The data show that the ability of the normal infant to explore by touch the various parts of his body appears to have a definite age of onset and a definite sequence.
