Abstract The present study investigated age-related differences in strategy use in the context of a numerosity judgment task. Eighty-two participants (37 adults, 20 sixth graders and 25 third graders) had to provide numerosity judgments of grids containing from 1 to 49 coloured squares. The choice/no-choice method was used to obtain unbiased estimates of the performance characteristics of strategies. Results showed that: (a) at all ages, the most common strategy was to add the number of… Expand
