The answer is secure attachment.
This type of attachment is typically associated with inconsistent or erratic caregiving, often linked to trauma or severe stress in the caregiver's life. Interactional synchrony, which involves a harmonious and responsive interaction between caregiver and child, is unlikely to produce this attachment style.
Avoidant attachment usually develops when caregivers are emotionally unavailable or unresponsive to the child's needs. Interactional synchrony, which involves being attuned and responsive, would not typically lead to avoidant attachment.
Secure attachment is characterized by a strong, healthy bond between caregiver and child, where the child feels safe and understood. Interactional synchrony, where the caregiver is responsive and in tune with the child's signals, fosters this type of attachment.
Ambivalent attachment often arises from inconsistent caregiving, where the caregiver's responses are unpredictable. While interactional synchrony involves consistent and responsive communication, it is not typically associated with ambivalent attachment.
