Example Question #1 : Somatosensation, Receptors, And Processing

In early infancy, movement is almost entirely considered to be which of the following?

Possible Answers:

Autonomic

Exploratory

Reflexive

All of these

Functional

Correct answer:

Reflexive

Explanation:

When we are infants, our movements are almost exclusively reflexive—healthy babies demonstrate the same general response to a specific type of stimuli. While most of these movements are technically functional (i.e. the rooting reflex serves the function of aiding in child in being able to eat), not all serve a specific purpose.

On the other hand, "autonomic" does not apply to movement, but rather to unconscious actions that keep our bodies in homeostasis, like our breathing. Very young infants have not yet developed the nervous system capabilities that allow for exploratory movements.
