Peer reviewedSweller, John; Levine, Marvin – Journal of Experimental Psychology: Learning, Memory, and Cognition, 1982
The operation of means-ends analysis (MEA) involves attempts at reducing differences between problem states and the goal state. It was paradoxically found that the more problem solvers knew of the goal state, the less they learned of the problem structure during the solution process. (PN)

Peer reviewedGriggs, Richard A.; Newstead, Stephen E. – Journal of Experimental Psychology: Learning, Memory, and Cognition, 1982
Four experiments were conducted to determine the source of difficulty of Wason's THOG problem. The THOG problem permits examination of the way people tackle a novel hypothetico-deductive problem. The results are interpreted as demonstrating the importance of problem presentation in problem solving. (Author/PN)
