Albert Stanley Bregman FRSC (September 15, 1936 – May 18, 2023) was a Canadian academic and researcher in experimental psychology, cognitive science, and Gestalt psychology, primarily in the perceptual organization of sound.

Bregman was known for having defined and conceptually organized the field of auditory scene analysis (ASA) in his 1990 book, Auditory Scene Analysis: the perceptual Organization of Sound (MIT Press). His ideas about ASA have provided a new framework for research in the auditory systems of both humans and non-human animals, for behavioral and neurological studies of speech perception, for music theory, hearing aids, audio technology, and the separation of speech from other sounds by computers (CASA). In acknowledgement of these contributions, he was called "the father of auditory scene analysis".

Until his death, Bregman held a post-retirement appointment at the rank of emeritus professor in the Department of Psychology at McGill University. Arriving at McGill in 1965, he became the first professor there to teach cognitive psychology. He also taught courses on Computer and Man, Research methods in experimental psychology, Learning Theory, Auditory Perception, Psychological Theory, and honors research seminars.

Many of Bregman's McGill undergraduate students have gone on to make significant contributions to intellectual life. These include Steven Pinker, Adam Gopnik, Paul Bloom, Stevan Harnad, Alfonso Caramazza, Marcel Just, Stephen McAdams, Bruce Walker, Susan Pinker, Alexander I. Rudnicky, and Alison Gopnik. His graduate students have included, among others, Gary L. Dannenbring, Valter Ciocca, Howard Steiger, Martine Turgeon, Poppy A.C. Crum, Michael Mills (Communications), James K. Wright (Music), and Francesco Tordini (Electrical Engineering). Postdoctoral fellows in his laboratory have included Richard Parncutt, Sheila Williams, and Brian Roberts. Prior to his official retirement, Daniel J. Levitin was hired as an assistant professor as his replacement, and they co-operated a laboratory together for several years, with Levitin eventually taking over and expanding the Bregman laboratory to the Levitin Laboratory for Music Cognition and Expertise.

Bregman was born to a Jewish family in Toronto, Ontario, Canada on September 15, 1936. His father was an office manager and his mother, a home-maker. He had one sister, who lives in Jerusalem, Israel. His wife is a retired history professor and active artist. He had three stepdaughters and two stepsons.

Bregman died on May 18, 2023, at the age of 86.

Bregman received a Bachelor of Arts degree from University College of the University of Toronto, with a concentration in Philosophy (ethics), in 1957. He received a master's degree in psychology, also from the University of Toronto, in 1959, after which he worked as a research assistant for two summers for Endel Tulving, studying how subjective organization affected the process of memorization. In 1963, he received a PhD degree from Yale University, where he had gone, in 1959, to study the formation of concepts with Carl I. Hovland. However, after Hovland died in 1961, he did his dissertation research on human memory, supervised by Fred D. Sheffield.

From 1962 to 1965, he was a research fellow at the Center for Cognitive Studies established by George A. Miller and Jerome S. Bruner at Harvard University, where he continued to study memory. There, he and Donald A. Norman set up one of the earliest computer systems for controlling psychological experiments, based on a PDP-4 computer. He also taught two courses in the Harvard Psychology Department. One was the laboratory section of a course in experimental psychology, taught by Richard Herrnstein; the other was a graduate seminar in learning theory.
