Query: The Ultimate Step In Understanding Chronic Behavior

Dr. Gerwe has written a remarkable book. Her creative talent has transformed reseach and technical information into a highly readable and fascinating conception. The integration of psychological findings with stories and case histories is particularly well done. The consumer will readily understand the academic concepts and apply them to his/her personal life experience. This work reminds me of the transitional breakthrough of B.F. Skinner's "Walden Two" and "Beyond Freedom And Dignity". A must read for students of human behavior...and for those of us who just struggle to survive! Three Cheers!
