For example, a critical aspect of understanding an explanation is to integrate the concepts and propositions in the explanation with existing knowledge.

The effect of prior experience on bias in time predictions on two different types of laboratory task was examined in two studies. Experiment 1 revealed that prior experience of performing a substantial part of the same task led to greater time prediction accuracy. However, contrary to the weight of previous research, there was little evidence of the temporal underestimation indicative of the pl...

The ability to respond eeectively and eeciently to crisis is an important objective in many problem-solving domains. In this paper, we identify three central elements of crisis: threat, urgency, and uncertainty. We deene the space of competent problem solvers for crisis response through a task analysis (Newell and Si-mon, 1972). Speciically, we bound the space of problem solvers by determining ...
