The Motor-Perceptual stage at three months for vocal development is the stage of babbling.
In terms of the vocal mechanism, the child is entering a stage called Babbling. This is a time of exploration of combinations of sounds which a baby can make. It is motor driven (reflexive); but it is perceived and correlated through the auditory modality (motor-perceptual)
Babbling, as we mentioned is an activity which is generated through genetic inheritance and is evidenced only in humans.
