5Production SystemsIn William Bechtel & George Graham (eds.), A Companion to Cognitive Science, Blackwell. 2017.“Fiiirre!” If someone were to shout that while you were in the midst of reading this essay, you would, like most people, stop reading and look around the room for the source of the shout, or the fire itself. You would also consider whether the likelihood of a fire was sufficiently high to cause you to take appropriate action – for example, locate a fire extinguisher, call the fire department, or leave the room. Of course, you have not been sitting around waiting for someone to yell “Fire!” You w…Read more

34Dual Space Search During Scientific ReasoningCognitive Science 12 (1): 1-48. 1988.The purpose of the two studies reported here was to develop an integrated model of the scientific reasoning process. Subjects were placed in a simulated scientific discovery context by first teaching them how to use an electronic device and then asking them to discover how a hitherto unencountered function worked. To do this task, subjects had to formulate hypotheses based on their prior knowledge, conduct experiments, and evaluate the results of their experiments. In the first study, using 20 a…Read more

35Solving Inductive Reasoning Problems in Mathematics: Not‐so‐Trivial PursuitCognitive Science 24 (2): 249-298. 2000.This study investigated the cognitive processes involved in inductive reasoning. Sixteen undergraduates solved quadratic function–finding problems and provided concurrent verbal protocols. Three fundamental areas of inductive activity were identified: Data Gathering, Pattern Finding, and Hypothesis Generation. These activities are evident in three different strategies that they used to successfully find functions. In all three strategies, Pattern Finding played a critical role not previously ide…Read more
