World Leading Expert-Performance Specialist, Bestselling Author
K. Anders Ericsson (born 1947) is a Swedish psychologist and Conradi Eminent Scholar and Professor of Psychology at Florida State University who is internationally recognized as a researcher in the psychological nature of expertise and human performance.
Currently, Ericsson studies expert performance in domains such as medicine, music, chess, and sports, focusing exclusively on extended deliberate practice (e.g., high concentration practice beyond one's comfort zone) as a means of how expert performers acquire their superior performance. Critically, Ericsson's program of research serves as a direct complement to other research that addresses cognitive ability, personality, interests, and other factors that help researchers understand and predict deliberate practice and expert performance.
In the domain of deliberate practice, Ericsson published an edited a book with Jacqui Smith Toward a General Theory of Expertise in 1991. His international bestseller “Peak - How all of us can achieve extraordinary results” was released in 2017 and translated into dozens of languages. Ericsson is also the co-editor of The Cambridge Handbook of Expertise and Expert Performance, a volume released in 2006. He is also Fellow of the American Psychological Association. Globally, Anders Ericsson is known as the inventor of the 10,000 hour rule.
