The Act in Context 
The Canonical Papers of Steven C. Hayes

The Canonical Papers of Steven C. Hayes is a compilation of his most pivotal articles written from 1982-2012. Through these selected papers, Hayes again revisits the theoretical struggles between behavioral and cognitive-behavior theories, taking us from the 1980s into present day, discussing the breakthroughs and follies. Using this as a focus point, he discusses the tradition of behavior analysis and its difficulties in addressing human language and cognition. Moving forward into the 90s, he chronicles the changes in a behavioral approach that emerge from a contextual perspective on human cognition, and lays out the foundation for a contextual behavioral science approach that he argues is more likely to lead to an understanding of human action and an alleviation of human suffering. Although the articles have previously been published, they have been edited and compiled ensure this branch of research is clear to the modern audience. The compilation was chosen by Dr. Hayes to enhance his vision for a functional contextual approach to complex human behavior.
