Errorless Establishment of a Match-to-Sample Form Discrimination in Preschool Children. I. A Modification of Animal Laboratory Procedures for Children, II. A Comparison of Errorless and Trial-and-Error Discrimination. Progress Report.
LeBlanc, Judith M.
A sequence of studies compared two types of discrimination formation: errorless learning and trial-and-error procedures. The subjects were three boys and five girls from a university preschool. The children performed the experimental tasks at a typical match-to-sample apparatus with one sample window above and four match (response) windows below. Each of the children performed eight tasks, each involving a fifty-two slide presentation in eight different sessions. The errorless and trial-and-error tasks were alternated. The task slides were pictures of geometric figures that were rotated at different angles from the sample orientation of 0 degrees. Results revealed that the design of the tasks was insufficient for the purposes of the experiment. No errorless learning occurred, because criterion discrimination was too difficult. Subsequent experimentation with adults indicated that the tasks were too similar to permit the desired comparisons. (MH)
