She was honored with the APA Award for Distinguished Scientific Contributions to Psychology in 2008 for having "greatly expanded scientific knowledge about cognition and its development in domains as varied as language, spatial cognition, quantitative thought, and memory."

Biography Huttenlocher (née Burns) was born in Buffalo, New York. She received her B.A. at the University of Buffalo in 1953, married her husband Peter Huttenlocher in 1954, and had three children.
