Attachment theory is a psychological framework that focuses on the bond formed between infants and their primary caregivers, usually their parents. This theory suggests that the quality of this early relationship has a significant impact on the child's emotional development and future relationships. Attachment research explores how attachment patterns are formed, their effects on emotional regulation and social behavior, and how they can be influenced by various factors such as parenting styles, traumatic experiences, and genetics. Researchers also study how individuals' attachment styles influence their relationships in adulthood and how they can be modified through therapy or interventions.
