Whether you have a secure or anxious style of attachment has a big impact on your life (see, attachment styles). Secure individuals have more successful relationships, better health outcomes, and are more likely to be happy. Anxious individuals have a more difficult time controlling their emotions, reacting to problems constructively, and maintaining their relationships.
New research shows just how problematic an anxious style of attachment can be. People were placed in a room with chocolate chip cookies and then asked to read a story about a secure or anxious relationship. People ate considerably more cookies after reading about the anxious relationship.
Hundreds of thousands of studies have been done on attachment styles. We now know that just thinking about being in an anxious relationship leads to increased snacking.
