Final answer:
A child who is not securely attached may demonstrate avoidant attachment, which is characterized by unresponsiveness to the parent and a lack of concern for their presence or absence.
Step-by-step explanation:
A child who is not securely attached may demonstrate avoidant attachment. This means that the child is unresponsive to the parent, does not use the parent as a secure base, and does not care if the parent leaves. The child may react to the parent the same way they react to a stranger. When the parent does return, the child may be slow to show a positive reaction. This behavior is not representative of a child who is securely attached.
