Final answer:
The Strange Situation is designed to stimulate the attachment system in infants to study their attachment styles with caregivers through a series of separations and reunions. Therefore correct option is D
Step-by-step explanation:
The purpose of the Strange Situation as an experimental procedure is to stimulate the attachment system and observe it under controlled conditions. Developed by Mary Ainsworth, this structured observational research method helps in the evaluation of different attachment styles between an infant and their caregiver. During the procedure, infants experience a series of separations and reunions with their caregivers, which allows researchers to observe the infants' reactions and thereby classify their attachment style as secure, avoidant, resistant, or disorganized.
It is important to note that while Ainsworth's study is foundational in understanding attachment, there has been criticism over factors such as the influence of a child's temperament and the lack of accounting for cultural differences in attachment behaviors. Nonetheless, the Strange Situation remains a significant method in the study of early emotional bonds and their effect on later behavior and development.
