    "subtitle": null,
    "abstract": "Diagram-based problem solving is an activity in which subjects \nsolve problems that are specified in the form of diagrams. Since \nthe diagram contains critical information necessary for problem \nsolving, this is an activity that clearly requires reasoning with \nthe diagram. Recent research on diagrammatic reasoning has \nuncovered many interesting aspects of this process. One such \naspect that the authors have been exploring, by means of a set of \nverbal and gestural protocol analysis experiments, is the role of \nthe diagram in guiding the reasoning process. The trajectory of \nreasoning is revealed both by the intermediate hypotheses gen?erated, and by the shifts of focus induced from problem solving \nprotocols. In this paper w e focus on the protocols collected for \na particularly interesting problem, one whose solution is ar?rived at through a pair of contradictory inferences. W e derived \nthe reasoning trajectories of subjects by extracting the temporal \norder and spatial distribution of their intermediate hypotheses \nleading toward the final solution. These trajectories indicate \nthat the spatio-temporal order of hypotheses depend on more \nthan the device structure depicted in the diagram and inferred \ncausation of events from the diagram. W e propose that subjects \nemploy impUcit search strategies which together with their in?ternal goals to verify hypotheses and the need to replenish short \nterm memory influence their reasoning trajectories",
