Abigail B. Calkin began using the standard celeration chart (SCC) in precision teaching in 1967. In the 1970s, she committed herself to investigations in precision inner behavior as she continued her work in special education, administration, and school psychology. Her role as a military wife led her to chair the Family Support Group during her husband’s third deployment. She joined ABAI’s Behavior Analysis in Military and Veterans Issues SIG at its first meeting in the early 2000s, a SIG she now co-chairs. In addition to inner behavior, her areas of investigation include PTSD and suicide. In 2016-2017, she was part of a pilot project with the Air National Guard to investigate suicide. She also has tens articles and book chapters and is the author of the memoir, The Soul of My Soldier, a collection of poems, short stories and essays, some of which mention behavioral techniques in her effort to spread the principles of the SCC and behavior analysis with those outside the field.
