Attachment Theory is a psychological framework that explains how early relationships with caregivers shape an individual's emotional and social development. Developed by John Bowlby, it suggests that children form attachments to their primary caregivers, which influence their future relationships and emotional well-being. Secure, anxious, and avoidant attachment styles emerge based on the caregiver's responsiveness and availability. The theory emphasizes the importance of a stable and nurturing environment during childhood. Secure attachments lead to healthier relationships in adulthood, while insecure attachments can result in difficulties in emotional regulation and interpersonal connections. Understanding these patterns can help in addressing mental health issues and improving relationships.
