A one-year old child is being left with a new babysitter for the first time, and the result is a strange situation. If the child is securely attached to his/her primary caregivers, then: 1.) How will the child behave when the caregiver leaves

The child will engage himself in free exploration to the surrounding, and also be happy upon the caregiver's return

Explanation:

According to the theories of John Bowlby (1988), a child is securely-attached if she is confident of her caregiver’s support. The attachment figure serves as a "secure base" from which the child can confidently explore the world.

The securely-attached child explores the room freely when his mother is present. He may be distressed when his mother leaves, and he explores less when she is absent. But he is happy when she returns.

If he cries, he approaches his mother and holds her tightly. He is comforted by being held, and, once comforted, he is soon ready to resume his independent exploration of the world. His mother is responsive to his needs. As a result, he knows he can depend on her when he is under stress (Ainsworth et al 1978)

Secure attachment is also associated with

keeping track of the caregiver during exploration,approaching or touching the caregiver when anxious or distressed;finding comfort in proximity and contact

And, in the long-term, kids with secure attachments seem to have many advantages - emotional, social, medical, and cognitive.
