According to Learning Theory, How Would Caregivers Respond to Infants

According to learning theory, how would caregivers respond to infants who appear disinterested in social interaction, smile little, and dislike physical contact?

A) Human caregivers have an innate need to protect the young and would provide equally good care to all infants regardless of how unrewarding the interactions might be.
B) Unsociable infants should receive little attention from their caregivers because interacting with unresponsive infants is not reinforcing.
C) Unsociable infants should receive a good deal of attention from their caregivers, because they are so undemanding.
D) Unsociable infants should receive high amounts of attention from their caregivers, because adult humans are driven to elicit reactions from even the most passive of infants.
