Bowlby and Ainsworth's attachment theory has had a big impact on modern psychology in several ways:

1. Understanding Attachment Styles:

   • Ainsworth found three main attachment styles in kids.
     • The first one, secure, is seen in about 66% of children.
     • The second, anxious, is found in about 20%.
     • The last one, avoidant, appears in about 14%.

2. Impact on Child Care Practices:

   • Research shows that when kids have secure attachments, they are better at managing their feelings and getting along with others.
   • About 70% of kids who are securely attached have fewer behavior problems as they grow up.

3. Foundation for Later Research:

   • Bowlby and Ainsworth’s work has helped create attachment-based therapies.
   • Today, about 40% of therapy options in psychology use these ideas.

This theory helps us understand how strong emotional connections with caregivers shape children’s lives.
