Daniel, You ask a good question at the end of your comments. I have read a lot of different studies about research conducted on reflective thought and how it impacts our problem solving as well as critical thinking. As a long time researcher in cognitive processing I have learned that we know very little about how the brain functions. I am amazed at how a brain can be traumatically injured and then through healing, medical support, therapy and personal effort reform pathways that enable the person to function again. (I work with TBI patients in another part of my life.). Gary Gary Meers, Ed.D.
