摘要：The purpose of this study was to teach children fractiondecimalequivalence using the respondent-type training procedureand test for any emergent generalization. In the first experiment,subjects were respondently trained on the conditionaldiscriminations; A 1--.8 1, A2--.82, and tested 8 1-A 1, 82-A2.Subjects were then trained on the conditional discriminationsC1 --.81 , C2--.82 and tested 81-C1, 82-C2. Subjects weresubsequently tested for the emergence of the untrained relationsA-C and C-A. When subjects were presented with the Stimulus A 1they observed 1/4 and when subjects were presented with A2 theyobserved 214. When subjects were presented with 81 theyobserved a circle with the upper left quarter shaded and whensubjects were presented with 82 they observed a circle dividedinto four quarters with the upper half shaded. When subjects werepresented with C1 they observed 0.25 and when subjects werepresented with C2 they observed 0.50. Experiment 2 was identicalto Experiment 1 except that subjects were administered threegeneralization tests. In Generalization Test Number 1, the StimuliA 1, A2, C1 , and C2 served as samples and shapes not seen intraining but with the same shaded areas served as comparisonstimuli. Generalization Test No.2 was identical to the previous test,except that the comparison stimuli consisted of a shape not seenin training and the shaded area was altered. Generalization TestNo. 3 was identical to the previous two tests except that thecomparison stimuli were altered in that the number of shaded andunshaded areas was increased. Experiment 3 was identical toExperiment 2 except that an extra generalization test was addedto the experiment. This test was identical to Generalization TestNo. 3 of Experiment 2, except that the shaded areas werecontiguous with each other.In Experiment 1, subjects were successful on all equivalencetests. In Experiment 2, subjects were successful on all equivalencetests and 50% of subjects successfully completed the finalgeneralization tests. In Experiment 3, subjects were successful onall equivalence tests and on all generalization tests.
