On January 4, 2016, the B. F. Skinner Foundation launched a new project – Skinner’s Quote of the Day. Quotes from B. F. Skinner’s works, selected by renowned scientists, appear daily Monday-Friday in order, starting with Chapter 1 of each book and running all the way through the last chapter. We started with the Science and Human Behavior (January-December 2916), followed by About Behaviorism (January-November 2017), Contingencies of Reinforcement (January-October 2018), Recent Issues (October 2018-May 2019), Reflections on Behaviorism and Society (May 2019-February 2020), and now moving on to Upon Further Reflection (from February 10 2020).

You can leave your comments here (registered users only), or join the discussion on our open Facebook forum. Please keep your comments brief and directly related to the quote.

Contingencies of Reinforcement. Chapter 7: The Phylogeny and Ontogeny of Behavior. Quote 15

"If, through evolutionary selection, a given response becomes easier and easier to condition as an operant, then some phylogenic behavior may have had an ontogenic origin." (pp. 203-204)   Subscribe…
