The role of perceptually represented structure in analogical problem solving.

Current models of analogical reasoning assume that representations of source examples and target problems occur in an amodal format--that is, a representation whose construction and processing are independent of activity in the perceptual and motor cortices of the brain. We examined the possible use of kinesthetic information--perceptual structures associated with the sensation of space and force--in the representation of source examples and target problems. Participants who recreated a source story while acting out the key elements were more likely to access the story when later working on the target problem than were participants who only verbally recreated the story or who verbally recreated it as well as sketched it. We argue that enactment made kinesthetic and spatial features more salient in participants' source story representations and that this aided performance. These results suggest that current models of analogical reasoning might be improved by including perceptual information as part of their representational schemes.

Case differences in the problem solving strategies of medical students and physicians.

Using a broad range of written patient management problems, this study examined 1) the influences of three medical information-gathering processes (history-taking, physical examination, and diagnostic studies) on the formulation of the differential and principal diagnosis by 175 medical students and 2) the extent to which the information-gathering processes used by the students paralleled the emphasis that experienced clinicians placed on these same processes. Results suggested that in 11 of 14 cases, the students appeared to be relying on specific information-gathering strategies in the formulation of the differential diagnosis, and that there were both similarities and differences in the relative emphases that these processes received from students and physicians.
