Margaret Ann Boden OBE FBA (born 26 November 1936) is a Research Professor of Cognitive Science in the Department of Informatics at the University of Sussex, where her work embraces the fields of artificial intelligence, psychology, philosophy, and cognitive and computer science.
Joy Paul Guilford (07 March 1897 to 26 November 1987) was an American psychologist best remembered for his psychometric study of human intelligence, including the distinction between convergent and divergent production.
Developing the views of L.L. Thurstone, Guilford rejected Charles Spearman’s view that intelligence could be characterized in a single numerical parameter. He proposed that three dimensions were necessary for accurate description: operations, content, and products. A Review of General Psychology survey, published in 2002, ranked Guilford as the 27th most cited psychologist of the 20th century.
