| Abstract: | Accuracy of imitation of nonsense words was examined in first- and second-grade children (65–99 months of age) as a function of prior reception training. Two experiments were conducted, involving within-subject comparisons. In the first, one group of words was trained as labels for nonsense objects, a second received noncontingent feedback yoked to the labeling words, a third was presented an equal number of times to control for exposure, and a fourth group was not included in the training phase. Testing involved accuracy of imitation of all four groups of words. Both the feedback and exposure words were imitated less accurately than the labeling words, but more accurately than the nonexposure controls. The second experiment examined the length of the label-object association, using an overtraining procedure. Words which came under the discriminative control of objects for greater numbers of trials were imitated more accurately than those meeting only a minimum discrimination criterion. |
