Charles Ferster

Charles Bohris Ferster (1 November 1922 – 3 February 1981) was an American behavioral psychologist. A pioneer of applied behavior analysis, he developed errorless learning and was a colleague of B.F. Skinner's at Harvard University, co-authoring the book Schedules of Reinforcement.

Career Ferster received his bachelor's degree at Rutgers University in 1947 followed by his Master's in 1948 and Ph.D. in 1958 from Columbia University. He then worked as a colleague with B. F. Skinner at Harvard University, where they established the Journal of the Experimental Analysis of Behavior in 1958. While at Harvard, he devised errorless learning to train animals, and used other forms of what was then termed behavior modification for clients with depression and obesity. While serving as an assistant professor of psychology at Indiana University School of Medicine from 1957 to 1962, Ferster employed errorless learning to instruct young autistic children how to speak.

Ferster's research also influenced the work of other pioneers of behavioral research, such as Donald M. Baer and Sidney Bijou, who together founded the Journal of Applied Behavior Analysis at the University of Kansas. Another well-known researcher was Ivar Lovaas, who applied Ferster's procedures to autistic children at the University of California, Los Angeles (UCLA) and developed early intensive behavioral intervention (EIBI), or 8 hours per day of what he called, "discrete trial training" (DTT).

Early childhood and family life Ferster was born November 1, 1922, in Freehold, New Jersey, the second son of Julius Ferster (1894–1969) and Mollie Ferster née Madwin (1895–1966), both Jewish immigrants from Poland (The Russian Empire, 1910 and 1912, respectively).

He was married to Marilyn Ferster, with whom he had four children—Bill, Andrea, Sam and Warren. He later married Elyce Zenoff Ferster, a professor of law at George Washington University,

Ferster died of a heart attack on February 3, 1981, at the age of 58 in Washington, D.C.

Laboratory work

Application of the theory Linwood Project Individualized Instruction at Georgetown, American Universities The University Learning Center at American University: this represented a radical experiment in undergraduate, interdisciplinary education in which the principles of operant behavior were directly applied. The center itself—an open, free-flowing physical space on campus—was conceived of as the "chamber" in which instruction and learning occurred. The environment adhered in obvious ways to such cornerstone concepts as immediate positive reinforcement, successive approximation, schedules of reinforcement, discriminative stimuli and the like. Professors of Psychology, Physics, Anthropology, Psychiatry, Sociology, Philosophy, Mathematics staffed the Learning Center, as did many graduate students in these fields.
