Trends in Problem-Solving Research: Twelve Recently Described Tasks

Abstract
Descriptions of the 12 problem-solving tasks developed since the last review (Ray, 1955) of chis topic indicate that the newer tasks are more sophisticated in design and provide for better experimental control than those used prior to 1953. Validity, reliability, sensitivity, trainability, problem structure, and problem difficulty are discussed as criteria for the selection of tasks to be used in studies of skilled problem-solving performance.
