D) begin paying attention to something or someone else.

Tronick's mutual-regulation model suggests that if Emmett's mother fails to pick him up after he signals, he will likely try another way of getting her attention, like crying. This is because mutual regulation involves a back-and-forth interaction between the infant and caregiver, with each partner influencing the other's behavior. Emmett is unlikely to become passive and withdrawn or pay attention to something or someone else, as these are not strategies that would likely result in his needs being met. While he may continue to smile initially, it is unlikely to be the only strategy he employs to try to get his mother's attention.
