Final answer:
The correct attachment style pairings are: a. Secure attachment for children thrilled when reunited with a caregiver, Disorganized attachment for children showing confused and erratic responses, and Avoidant attachment for those who don't care when reunited with a caregiver.
Step-by-step explanation:
The correct option : a
In secure attachment, children exhibit distress when separated from caregivers and are thrilled when reunited, demonstrating they prefer their caregiver over strangers and using them as a secure base for exploration. Children with disorganized attachment show a confused, erratic response upon the return of their caregiver, often acting in unconventional or odd ways that may indicate a disrupted ability to regulate emotions due to negative experiences like abuse.
Avoidant attachment is characterized by children showing indifference to a caregiver's presence or absence, and they do not seek comfort from them upon reunion, which can reflect past insensitive caregiving experiences. These attachment behaviors are identifiable using the Ainsworth Strange Situation procedure, and they influence the way children relate to their caregivers and their surroundings.
