Recent studies have looked at which areas of the human brain play a role in attachment.

Around 70-80% of people experience no significant changes in attachment styles over time.

Changes in attachment are often associated with negative life events, as described below.

That somewhere in his attachment to Jacob there'd been sexual feeling?

These areas of the brain were involved in both romantic and parental attachment.

"She's at Duke right now, giving a paper on the role of fantasy in romantic attachment."

She could not flatter herself with any idea of blindness in his attachment to her.

However, a categorical model is not necessarily the best representation of individual difference in attachment.

These findings have opened the door to future studies clarifying how different areas of the brain function in attachment.

Changes in attachment for one relationship did not affect the perception of support in other relationships.
