Social Attachment Theory is a psychological concept that explains how humans form emotional bonds with others. This theory was first introduced by John Bowlby, a British psychologist, in the 1950s.

According to Bowlby’s theory, infants develop an attachment to their primary caregiver through repeated interactions and experiences. This attachment then affects their future relationships with others.

How does Social Attachment Theory work?

Infants are born with an innate need for attachment. They instinctively seek out people who can provide them with comfort and security.

As they grow and develop, they learn to differentiate between familiar and unfamiliar people. Infants will form an attachment with whoever provides them with the most consistent care and attention.

This attachment is crucial because it provides the infant with a secure base from which to explore the world around them. When the infant feels safe and secure in their attachment relationship, they are more likely to explore their environment, interact with others, and develop new skills.

The Four Types of Attachment Styles

Bowlby identified four different types of attachment styles: secure, avoidant, ambivalent/resistant, and disorganized/disoriented.

The Impact of Attachment on Adult Relationships

Attachment styles established in childhood can have a significant impact on adult relationships. Individuals who have a secure attachment style tend to form healthy, long-lasting relationships. On the other hand, individuals with an insecure attachment style may struggle with intimacy and emotional vulnerability.


Social Attachment Theory is an essential concept in understanding how humans form emotional bonds with others. Bowlby’s theory explains how the quality of the attachment relationship with a primary caregiver can affect an individual’s future relationships. By understanding the different attachment styles, we can better understand ourselves and our relationship patterns.
