As one might expect from the founder of Precision Teaching, Ogden Lindsley was precise in creating the summaries of his presentations. Ogden took the opportunity to share his latest thinking on a topic in his presentations. However, because the presentation summaries have not been published, many people have missed the advantage of this knowledge. At the request of Rick Kubina, "JPTC" editor, I agreed to write my reaction to four of Og's presentations. These summaries cover presentations between May 1999 and October 2001. One summary discusses the connection between the Suzuki music teaching system and Precision Teaching, four summaries are related to autism, and the last summary addresses the role of Precision Teaching in decision making.
