Albert F. Smith is a cognitive psychologist in the Psychology Department at Cleveland State University (Cleveland, Ohio). . Subsequently, much of his research has involved collaborating with nutritionists, dietitians, and epidemiologists to enrich the methodology of dietary validation studies; to investigate factors that contribute systematically to errors in dietary reporting; to understand the circumstances under which those factors contribute to reporting error; and to devise ways to improve dietary reporting accuracy.
