Overview
Jerome L. Singer (February 6, 1924 – December 14, 2019) was an American psychologist whose work helped establish the scientific study of daydreaming and imaginative thought within cognitive and clinical psychology. A long‑time faculty member at Yale School of Medicine, Singer combined experimental methods and clinical observation to explore how spontaneous mental activity affects emotion, creativity and daily functioning.
Research focus and contributions
Singer investigated the content, frequency and psychological role of spontaneous thoughts often called daydreams. He emphasized that inner experience ranges from brief mind wandering to vivid, constructive imagining, and he sought reliable ways to describe and measure those experiences. His research helped shift popular views of daydreaming from trivial or pathological to a topic with adaptive and maladaptive aspects worthy of scientific study.
Methods, themes and examples
Across laboratory studies and questionnaire work, Singer examined how daydreaming relates to mood, problem solving, creativity and personality. He advocated using self‑report instruments and behavioral tasks to capture individual differences in imaginative involvement. Practical examples of his interests include how imagined scenarios facilitate planning or how recurrent negative fantasies relate to distress.
Career and biography
Singer was born in New York City and completed his education at the University of Pennsylvania before joining the faculty at Yale School of Medicine, where he became Professor Emeritus of Psychology. He served as a mentor to students and contributed to the broader development of psychological science during a long academic career.
Honors, legacy and influence
Recognized as a fellow of major scientific organizations, Singer was elected to the American Psychological Association, the American Association for the Advancement of Science and the New York Academy of Sciences. Popular accounts sometimes call him "the father of daydreaming" for his role in legitimizing research on spontaneous mental imagery; readers can follow further summaries of his work on pages about daydreaming research. He died in New Haven at age 95.
