- Developmental Psychology
- Attachment Theory
Background:
- Childhood maltreatment is a known risk factor for insecure attachment.
- Empirical evidence on the strength and direction of this relationship is mixed.
Purpose of the Study:
- To estimate the overall associations between childhood maltreatment and adult attachment.

Theory of Romantic Attachment in Adulthood
Attachment is a long-standing connection or bond with others. While Attachment Theory was conceived in developmental psychology to describe infant-caregiver bonding, it's been extended into adulthood to include romantic relationships.
Attachment
Attachment is vital for infant development, as warm social interactions support growth and well-being. In a classic 1958 study by Harry Harlow, the significance of warmth and comfort in forming attachments was examined. Harlow separated newborn monkeys from their mothers and provided two artificial "mothers": one made of cold wire and the other covered in soft cloth. Despite the wire mother offering food, the infant monkeys preferred the comfort of the cloth mother, demonstrating that physical...
Hazan and Shaver's Attachment Styles
Attachment theory, developed initially to explain infant–caregiver bonds, has been extended to illuminate patterns of intimacy in adult romantic relationships. Psychologists Cindy Hazan and Phillip Shaver proposed that the attachment styles observed in infancy form a framework for how individuals approach emotional closeness and conflict in adulthood. These attachment styles—secure, avoidant, and anxious—are linked to enduring patterns of behavior and emotional regulation in adult relationships.
Attachment Styles
Jeffrey Simpson's attachment theory suggests that early caregiver relationships shape lasting patterns of behavior and emotional regulation, known as attachment styles. These patterns are organized along two key dimensions: self-esteem and interpersonal trust. The intersection of these dimensions produces four primary attachment styles that typically persist throughout life and significantly influence how individuals form and maintain relationships.Secure Attachment StyleIndividuals with a...
Relationship with Parents: Attachment
Parent-child interactions lay the foundation for how we understand relationships throughout life. These interactions are not uniform across families; instead, they are shaped by a range of environmental, emotional, and behavioral factors unique to each caregiver-child dynamic. Social psychologists study these early relationships to understand how patterns formed in infancy influence social functioning and interpersonal behavior in adulthood.Attachment Theory and Early Relational ModelsJohn...
Relationship with Other Adult Family Members and Siblings
Other adult family members and siblings play a crucial role in shaping children’s social and emotional development. While parents or primary caregivers are often the central figures in early attachment and socialization, other adults in a child’s life, such as grandparents, aunts, and uncles, can significantly influence developmental outcomes. These influences depend on each adult’s personality and may help compensate when a primary caregiver is emotionally distant or inconsistent. For...
