In Mahler's theory, the symbiotic phase refers to the infant's absolute dependence on which caregiver?

• A. Father
• B. Sibling
• C. Grandparent
• D. Mother

Answer: (D)

In Mahler's theory, the symbiotic phase is when the infant experiences a merging with the primary caregiver and relies entirely on that person for needs and comfort. The infant has no clear sense of self separate from the caregiver, so there is absolute dependence on the caregiver, who is typically the mother. This caregiver provides the essential reassurance, feeding, warmth, and soothing that the infant cannot yet obtain independently. Other people, like fathers, siblings, or grandparents, may contribute to care but do not serve as the infant’s primary object in this stage, so they don’t represent the same absolute dependence.
