​​As you might be aware, fluency-based instruction and Precision Teaching evolved from more than a decade of incredibly productive, groundbreaking laboratory research by Ogden R. Lindsley. Lindsley brought Skinner's behavior science into the laboratory study of human
behavior, with a commitment to Skinner's measure, rate of response or (as Lindsley preferred to call it) behavior frequency.

This page contains a nearly complete archive of Lindsley's publications and unpublished reports, including those from before to his transition from Harvard Medical School and the Behavior Research Lab at the Metropolitan State Hospital to the University of Kansas. We've assembled these documents here because many of those who practice fluency-based instruction and performance improvement have not had the opportunity to study Lindsley's earlier work, much of which is currently difficult to access.

We also decided to put his publications and presentations related to Precision Teaching here, because the list is so extensive. Rather than combining his work with those who came afterward, we decided to give Ogden a page of his own.

Many of these documents came originally from B.H. Barrett's extensive collection of research papers (Barrett completed a postdoctoral fellowship with Lindsley and Skinner before building her own human behavior laboratory), as well as from my own archive. More recent additions came from Lindsley's collection of publications and reports at Behavior Reseach Company, thanks to the generosity of Nancy Hughes, his long-time life partner.
