Final answer:
The item 'resilient' is not an attachment style; the recognized styles are secure, avoidant, insecure, and disorganized. 'Resilient' is not associated with the types of attachment described by Ainsworth in her studies of infant-caregiver relationships.
Step-by-step explanation:
The item that is NOT an attachment style is B. resilient. Attachment styles refer to patterns of attachment a child develops towards their parents or caregivers, which were first described by psychologist Mary Ainsworth. The recognized attachment styles include secure, avoidant, insecure, and disorganized attachment. 'Resilient' is not a category used to describe an attachment style.
Attachment Styles Explanation
A child who uses the parent as a base from which to explore their world is displaying a secure attachment style. In this form of attachment, the child feels comforted by the presence of their caregiver and will seek them out in times of stress. Secure attachment is considered the healthiest form, as the caregivers are responsive to the child's needs. On the other side, with avoidant attachment, a child may seem indifferent to the presence of a caregiver and does not seek much comfort or contact from them, often due to the caregiver's insensitivity or inattentiveness.
