Final answer:
In the Strange Situation experiment, infants who stay calm when their mother leaves, accept the stranger, and avoid their mother when she returns, display anxious-avoidant attachment, signifying a detachment due to a caregiver who was not responsive to their needs. Hence, option B is correct.
Step-by-step explanation:
In the Strange Situation experiment, infants who remain calm when their mother leaves, accept the presence of a stranger and ignore or avoid their mother upon her return display signs of anxious-avoidant attachment. This behavior is characterized by the infant showing minimal interest or response to the caregiver's absence or return, treating them with a similar detachment as they would a stranger.
An infant with an anxious-avoidant attachment style may have experienced a caregiver who was regularly insensitive and inattentive to their needs, leading the infant to adopt a self-reliant approach and avoid seeking comfort from the caregiver.
In contrast, children with a secure attachment are upset by the caregiver's departure but are happy to see them upon return, using them as a secure base from which to explore their environment. Those with an anxious-resistant attachment show clinginess and difficulty being comforted upon reunion.
Disorganized attachment is characterized by erratic or odd behaviors upon caregiver reunion, often seen in children who have experienced abuse or extreme inconsistency in caregiving.
