Abstract : Subjects' performance on tests of immediate and delayed retention was measured following instruction by two versions of an autoinstructional program: one verion employed vanishing (the successive reduction of stimulus support) and the other did not. Classes of 4th-, 5th-, and 6thgrade students served as Ss. No significant difference between the performance of Ss who hd used the vanishing and the nonvanishing versions of the program was found on the immediate test. On the test taken two weeks after iniial training, however, the Ss who had used the vanishing version of the program were found to have retained signifcantly more than Ss who had used the nonvanishing version. The results are interpreted in terms of the effects of context varibles upon retention. (Author)
