The variables number of experimenters and type of context in children's performance in conservation task: the problem of standardization of clinical method in classical testing

Angela Donato Oliva Maria Lúcia Seidl de Moura About the authors

This study tested the influence of the variables number of experimenters (one or two) and type of context (with game or with no-game) in children's performance in conservation task. Ninety six 5-7 years old children from a Rio de Janeiro's school were randomly distributed between 4 conditions and tested individually on a task involving conservation of discontinuous quantity. The conditions were: game context and one experimenter, game context and two experimenters, two experimenters and no-game context, and classical context (one experimenter and no-game). The results were analyzed by the Logistic Regression and offered clear evidence of the increasing frequency of correct responses in the groups with game context with 1 or 2 experimenters, and in the no-game context with 2 experimenters, but no interaction was observed. Possible problems with the procedures regularly employed in piagetian researches are discussed.
