Previous replication studies have met with discrepant results in their attempts to evaluate Piaget and Inhelder's study of chance and probability concepts in children. Consequently, 56 subjects (aged 5-4 to 17-11) were tested on 2 cognitive tasks taken from the authors' original work. Specific objections to Piaget and Inhelder's experimental and analytic procedures are overcome here by utilizing a scoring procedure which elicits item-type data from relatively standardized interviews. The results of this replication study indicate considerable agreement with Piaget and Inhelder's description of stage-related verbal features while failing to confirm their description of stage-related nonverbal features. Evidence from this study is related to the concept of "stage" in cognitive-developmental theory, and the procedures used here are evaluated vis-`a-vis developmental issues.
