Preface
No full textOn Friday 24th May 2013, William T. Powers, the founder of perceptual control theory (PCT), sadly passed away. This book is dedicated to him. I owe him a debt of gratitude. Without his scientific discoveries - my work, my world, and my life, would not make quite as much sense as they do today. Many of my colleagues have had a similar loss. And because Bill continued to be so generous with his time, patient in the face of persistent questions, and crystal clear in his reasoning, the loss was that much greater for all of us. There will no doubt be a story of Bill Powers' incredible life as an engineer, inventor, scientist, mentor, friend, father, brother, and son, but this book is not that book. This is the book that he wanted written by the many people with whom he had shared his vision. Each of them had gone on to share, test, or use his ideas in very different ways, in diverse academic fields, all with Bill's support and of course, feedback. I must particularly thank Alice Powers McElhone, Bill's sister, who through her business, Benchmark Publications, ensured the continued publication of Behavior: The Control of Perception, Bill's first book, as well as the publication of his subsequent works, Making Sense of Behavior and Living Control Systems I, II, and III. From 2013 to 2018, Alice nearly brought the publication of this final book in the Living Control Systems series to completion. We are extremely grateful to Elsevier for taking her good work to the finish line in time for her to witness the fruit of her labors
Ten vital elements of perceptual control theory, tracing the pathway from implicit influence to scientific advance.
No full textThe central tenet of Perceptual Control Theory (PCT) is that ‘behavior is the control of perception’. From this tenet, a series of further elements are utiized to provide the necessary conceptual and mathematical detail for building and testing functional models of the behavior of humans, animals and purposeful machines. This chapter traces the elements of PCT, and their empirical scrutiny and critique, across multiple scientific disciplines to converge on a contemporary evaluation of the scientific status of PCT as an interdisciplinary theory of behavior. The chapter concludes with key recommendations for future research and the development of the theory
The belief that being high is a natural part of your personality predicts an increase in manic symptoms over time in bipolar disorder
No full textBackground: several psychological models of bipolar disorder propose that certain types of appraisals can lead to increases in manic symptoms.Aims: We tested whether the belief that being ‘high’ is a natural part of one’s personality correlates with manic symptoms four months later when controlling for manic symptoms at baseline. Method: a prospective four-month follow-up design using self-report measures. Forty people with a diagnosis of bipolar disorder completed a measure of manic symptoms, a measure of appraisals associated with bipolar disorder, and a single-item measure, “To what extent do you feel like being ‘high’ is a natural part of your personality”, at baseline and follow up.Results: the single-item measure showed modest stability over time and construct validity in its correlation with a standardised measure of appraisals in bipolar disorder. As predicted, the single-item measure correlated with manic symptoms at follow up when controlling for manic symptoms at baseline.Conclusions: the belief that being ‘high’ is a natural part of one’s personality is a potential predictor of manic symptoms. Further research needs to study the potential mediating mechanisms such as activating behaviours, and control for indicators of the bipolar endophenotype
Method of Levels Therapy
No full textMethod of Levels (MOL) is a psychological therapy based on perceptual control theory. MOL involves the therapist asking curious questions to help the client talk freely and openly about a problem to explore their own solutions. MOL helps a client to shift and sustain attention on the source of conflict between important life goals. MOL has unique features that make it particularly flexible, accessible and efficient. It is transdiagnostic and can be applied unchanged across a range of presenting problems and psychiatric diagnoses. Clients are in control of MOL. They can schedule appointments to suit them or their institution (e.g. schools, wards, prisons), they can choose their own problem to focus on for each session, and they can continue the intervention until they perceive that they no longer need it. We explain the theory and practice of MOL, its history, and its current empirical status

Warren G. Harding letter to Adolphe Danziger, February 21, 1921
No full textIn this letter dated February 21, 1921, President-elect Warren G. Harding writes to Adolphe Danziger, a Jewish scholar, lawyer and author, to thank him for the poem he wrote honoring Harding titled "Within the Storm."
This letter is part of the Warren G. Harding Papers (MSS 345). This collection includes correspondence, business records, and other materials documenting Harding’s business career as owner and editor-in-chief of The Daily Marion Star, as well as the various stages of his political career. A significant portion of the collection, and what’s available on Ohio Memory, highlights his 1920 presidential campaign, spanning just before publicly announcing his candidacy to handily defeating Ohio Governor James M. Cox in the election. Correspondents include both Ohio and national businessmen, political figures, and ordinary citizens writing with questions, support, congratulatory notes, and campaign advice. Some of the most interesting insights into the tumultuous political climate in the U.S., the extreme factionalism within the Republican Party in Ohio, and Harding’s campaign strategies are described in letters between Harding and his campaign manager, Harry M. Daugherty. Some of the topics addressed include women’s suffrage, Prohibition, the League of Nations, African American representation and issues, and lingering peace negotiations following World War I
