Steven C. Hayes is Nevada foundation professor in the behavior analysis program at the University of Nevada, Reno.
An author of 44 books and nearly 600 scientific articles, his career has focused on an analysis of the nature of human language and cognition and the application of this to the understanding and alleviation of human suffering. He is the developer of Relational Frame Theory, an account of human higher cognition, and has guided its extension to Acceptance and Commitment Therapy (ACT), a popular evidence-based form of psychotherapy that uses mindfulness, acceptance and values-based methods.
Hayes has been president of Division 25 of the APA, the American Association of Applied and Preventive Psychology, the Association for Behavioral and Cognitive Therapy and the Association for Contextual Behavioral Science (ACBS), which is an 8,300 member international society that is organized around the approaches he helped create. He was the first secretary-treasurer of the Association for Psychological Science, which he helped form as chair of its initial organizing committee, and has served a five-year term on the National Advisory Council for Drug Abuse in the National Institutes of Health.
In 1992, he was listed by the Institute for Scientific Information as the 30th "highest impact" psychologist in the world. His work has been recognized by several awards including the Exemplary Contributions to Basic Behavioral Research and Its Applications from Division 25 of APA, the Impact of Science on Application award from the Society for the Advancement of Behavior Analysis, and the Lifetime Achievement Award from the Association for Behavioral and Cognitive Therapy. Google Scholar data ranks him among the top ~1,300 most cited scholars in all areas of study, living and dead (http://www.webometrics.info/en/node/58). His TEDx talks (bit.ly/StevesFirstTED and bit.ly/StevesSecondTED) have been viewed by nearly 200,000 people.
Hayes is interested in the application of contextualistic perspectives to conceptual, methodological and technological problems in psychology, both applied and basic. Stated another way, he is working to foster the development of contextual behavioral science. Also, Hayes studies professional organizational work, administration, teaching and supervision, clinical practice and other applied work and research.

- Steven Hayes Knowledge in a Nanosecond
- Integration of behavioral and biological science. He is interested in how to nest contextual behavioral psychology into modern evolution science.
- Philosophy of science. He has worked to develop functional contextualism as a viable philosophical system and to explore its implications for behavioral and biological sciences.
- Methodology and research strategy. He has focused on how to link functional contextual thinking to methodological and strategic issues such areas as time-series (single-case) designs, the role of theory, effectiveness research, treatment utility as a method of determining the value of assessment, and process research.
- Assessment: He has worked on new measures of experiential avoidance, values and cognitive fusion in various specific areas.
- Basic psychology: He has worked to develop and test a comprehensive, experimentally based functional contextual analysis of the nature of the human language and cognition: Relational Frame Theory (RFT)
- Psychopathology: Hayes has explored the role of experiential avoidance, cognitive fusion, loss of contact with the moment, lack of values clarify, rule-based psychological inflexibility and similar processes in the creation of human suffering.
- Clinical application: He has worked to develop and test a functional contextual approach to human problems, Acceptance and Commitment Therapy (ACT).
- Nonclinical applications: He has worked to apply RFT to such areas as education or social bias, and to create intervention technologies based on ACT for problems, such as stigma and prejudice.
Hayes' interests are not defined particularly by population or problem. He has done work in the past few years with anxiety, depression, psychosis, prejudice, burnout, stress, diabetes, weight control, sleeping, smoking, pain, and substance abuse, among other areas.
