Final answer:
Children with secure attachment use their caregiver as a secure base, while children with avoidant attachment do not rely on their caregiver as a secure base. Children with ambivalent/resistant attachment display clingy behavior but reject their caregiver's attempts to interact, and children with disorganized attachment behave erratically.
Step-by-step explanation:
In the Strange Situation experiment, children with secure attachment use their caregiver as a secure base to explore their environment. They return to their caregiver for comfort and support, especially during times of stress. On the other hand, children with avoidant attachment do not rely on their caregiver as a secure base and do not show a positive reaction when the caregiver returns. Children with ambivalent/resistant attachment display clingy behavior but reject their caregiver's attempts to interact. Lastly, children with disorganized attachment behave erratically and can't regulate their emotions.
