Abstract
Two students with autism were trained to make coin combinations corresponding to printed prices with a three digit number. In initial training, a constructed-response matching-to-sample task was used . On each trial, students were presented with a printed price and a choice pool containing 1-yen coins, 10-yen coins, and 100-yen coins, and were required to select coins from the choice pool in response to the presented price. Under these training conditions, however, neither student reached criterion performance. Analysis of error patterns suggested that learners failed to acquire reliable discrimination competence to distinguish between the three kinds of coins conditional upon each digit in the printed prices. Next, the standard matching-to-sample procedure with coin-combinations as samples and printed prices as comparison stimuli was introduced. After this training, students were able to construct coin combinations corresponding to printed prices. Results are discussed in terms of training procedures for students with autism for responding to compound stimuli.
