When a newborn infant is touched on the cheek the infant will turn its head toward the source os stimulation this behavior is known as?

I believe the answer is rooting

Rooting refers to the type of characteristic that automatically implanted in our brain ever since we brain. (such as how to cry, how to turn heads, how to sleep, etc) The infants would automatically turn their head toward source of stimuli in order to obtain nutrients that are necessary for their survival.
