This is an updated edition of a volume first published in 1977 examining the state of Learning Theory at that time, and examining basic questions about whether operant and Pavlovian conditioning could be isolated either procedurally or in their real life effects. The book examines the inevitable interactions that occur between operant and Pavlovian conditioning across a variety of paradigms. The original volume stemmed from a conference organized by myself and Harry Hurwitz at the University of Guelph in Ontario Canada in 1975. There were 14 participants, 10 of whom presented papers which appear here as chapters. These chapters offer a glimpse into the state of Learning theory nearly 50 years ago.
The highlight of any conference such as this, stems from the interactions between participants. Typically, these moments, as inspired as they may be, are lost to history. In this case, they were recorded, transcribed and included as part of the text that follows each chapter. These animated discussions offered an ideal integration of the topics covered in the 10 chapters, as well as a deeper look at some of the contributors. As of this writing, five of the original 10 authors have died. I was gratified when Routledge Publishing contacted me in 2021 to notify me of their intention to update and republish the original edit.
