Digit comparison is strongly related to individual differences in children's arithmetic ability. Why this is the case, however, remains unclear to date. Therefore, we investigated the relative contribution of three possible cognitive mechanisms in first and second graders' digit comparison performance: digit identification, digit--number word…

Research was done to investigate the interfunctional relationships between a child's ability to order a set of objects and the development of language descriptives used to describe differing aspects of a group of objects which had been ordered. Results show that mean age of concrete operation acquisition is 7.1 years. (Author/JB)

These four studies in a series deal with good and poor readers' utilization of selected cues in paired-associate learning. Specific cues considered were color, order of presentation, and verbal mediators. Answers to two basic questions were sought: (1) Do the selected cues have a facilitative effect upon children's paired-associate learning? (2)…

The purposes of this study were to: (1) determine the influence of a series of experiences involving the equivalence relation "same length as" and the asymmetric transitive relations "longer than" and "shorter than" on the ability of first and second grade children to classify and seriate objects on the basis of length; (2) investigate the…
