Abstract
This study was designed to determine whether the acquisition of second-orde r conditional discriminations becomes more rapid across new discriminations . Three normal grade-school children served as subjects. In general, perfor mances improved across sets of second-order discriminations. Moreover, ther e was little disruption of performance when the second-order stimuli were c hanged from discrete forms to being compounded with the sample stimuli. Err ors increased markedly when the second-order conditional discrimination shi fted from one in which one second-order conditional stimulus indicated that the original contingencies were reversed to a condition in which one secon d-order conditional stimulus indicated that the subject should select the s ame comparison stimulus regardless of which sample form was present. Errors prior to mastery decreased, however, across problems of the new type-thus reproducing the learning-set outcome with new stimuli.
