Abstract : Interests in the fields of induction and problem solving are combined in a program called the Aptitude Test Taker, which forms a conceptualization from worked examples of an inductive reasoning task and organizes a computer program to perform the task. The development of the Aptitude Test Taker was influenced both by computer models of human performance and artificial intelligence research. The evolution of the Aptitude Test Taker was guided by detailed human performance data. The Aptitude Test Taker is a knowledgeable conceptualizer using feature extraction to induct a performance strategy. Unlike earlier attempts at developing a performance strategy from worked examples of the task, the Aptitude Test Taker uses a parsimonious set of examples rather than requiring examples of every situation that will be encountered. The performance of the Aptitude Test Taker, on tasks within its capability, parallels human performance and exceeds the performance of the other computer programs that can deal with one or more of the tasks. Other programs that solve similar reasoning tasks do not induct a performance strategy from examples. (Author)
