Quizplus · Accepted Answer

In the first habits and primary circular reactions substage (which occurs between 1-4 months), infants begin to coordinate sensation and movement more intentionally. They also start to repeat actions that have favorable outcomes. Josh's sucking behavior is an example of a primary circular reaction, where he is repeating a pleasurable action (sucking) on his own body.
