title: Frequency judgment accuracy as a function of age and school achievement (learning disabled versus non-learning-disabled) patterns.
abstract: The accuracy of children's judgments of relative situational frequency was examined in two experiments. In Experiment 1 children with normal achievement in Grades 2 and 3 were compared with such children in Grades K and 5, as well as with three groups of low-achieving children in Grades 2 and 3. These latter groups consisted of children low in reading achievement, those low in math achievement, and those identified as learning disabled. Frequency judgment accuracy increased from kindergarten to Grades 2 and 3. No other comparisons yielded significant differences. Experiment 2 confirmed both the above age difference and the absence of any frequency judgment deficiency on the part of the low-achieving groups.
