After leaving this position, she spent time researching mother-child interactions in Uganda.

After returning to the U.S., Ainsworth took a position at John Hopkins University.

She divorced in 1960 and underwent therapy that contributed to her interest inpsychoanalytic theory.

In addition to Ainsworth’s three styles, other researchers identified a fourth style known as disorganized-insecure attachment.

While these styles change with time and experience, researchers believe that childhood attachment styles influence adult romantic attachments.

Adults with a secure romantic attachment style tend to have lasting relationships and believe love is enduring.

Those with aninsecure romantic attachment stylebelieve that love is more temporary.
