Two modes of mental representation and problem solution in syllogistic reasoning.
In this paper, the theory of syllogistic reasoning proposed by Johnson-Laird (1983, 1986; Johnson-Laird & Bara, 1984; Johnson-Laird & Byrne, 1991) is shown to be inadequate and an alternative theory is put forward. Protocols of people attempting to solve syllogistic problems and explaining to another person how they reached their conclusions were obtained. Two main groups of subjects were identified. One group represented the relationship between classes in a spatial manner that was supplemented by a verbal representation. The other group used a primarily verbal representation. A detailed theory of the processes for both groups is given.
