| Abstract: | Nevin provides a scientific role model, illustrating momentum in his own research and providing impetus through his effects on the scientific behavior of his students and his colleagues. I discuss his book in the context of a review of the history of the concept of extinction, I cite his introduction of signal‐detection analysis into behavior analysis as a contribution not covered in this book, I briefly consider applications, such as the potential extension to fluency procedures in education, and I critique his concept of momentum, relating it to other metaphors for maintained behavior such as the dynamics of sensory systems and robustness in biological accounts of the stability of phenotypes. |
