“Divergent thinking: Imaginative thinking, characterized by the generation of multiple possible solutions to a problem, often associated with creativity. The concept was introduced in 1946 by the US psychologist J(oy) P(aul) Guilford (1897-1987) and is one of the five different types of mental operations in Guilford’s cube.”
