Bailey is an infant boy who is sitting in his car seat. he is waving his hands around and his thumb accidentally touches his cheek. he turns his head toward his thumb and he puts his thumb into his mouth. he begins to suck on it and finds that he likes it. he quickly learns to put his thumb into his mouth and suck on it whenever he wants to. what sensorimotor substage does this illustrate?
The answer is the Primary Circular Reactions. In this sub
stage, it comprises synchronizing sensation and new schemas. For instance,
a kid may suck his or her thumb by coincidence and then later deliberately reprise
the act. These actions are recurring for the reason that the infant discovers
them pleasing.
