Final answer:
Babies who avoid contact after parent-child separation display an avoidant attachment. Such attachment arises from caregivers being inattentive to the child's needs, a concept identified by Ainsworth's Strange Situation procedure.
Step-by-step explanation:
Babies who avoid contact with their parents after separation or who ignore parent's efforts to interact with them have a(n) avoidant attachment. This attachment style is noted by a lack of responsiveness to the parent, a lack of concern when the parent leaves the room, and when the parent returns, such children are slow to show a positive reaction, treating the parent similarly to a stranger. The primary caregiver in such cases is often insensitive or inattentive to the child's needs, according to research by Mary Ainsworth and her colleagues. These various attachment styles, including secure attachment, resistant attachment, and others, were identified through the Strange Situation procedure, which illustrates how infants bond differently with caregivers and how such bonds affect their behavior.
