Results indicate that scale values can be approximated satisfactorily through item-examinee sampling. Defining one observation as the response made by one examinee to one item, the similarity between the estimated scale values and normative scale values increased generally with increases in the number of observations acquired by the sampling plan.…

The results of this study of 24 9- and 10-year-old normal children indicated that by 9 years of age, children spontaneously adopt both ear and temporal recall strategies under the same conditions as do adults. The children readily switch from one recall strategy to the other as a function of the rate input of the material. (WY)
