Click for Joy! Foreword and Introduction

It was Karen Pryor who popularized the term and the practice of clicker training. Her 1985 book, Don't Shoot the Dog, captured the public's interest, and its appearance inadvertently led to a widespread assumption that clicker training was new. In fact, as Pryor herself explained in the introduction to her book, clicker training is based on the science and technology of operant conditioning and has been used since the 1940s.
