Number of simple addition problems (out of 14 possible) correctly solved with direct retrieval of the answer (Panel A) or with use of the decomposition strategy (Panel B). Number of complex addition problems (out of 6 possible) solved with use of the decomposition strategy (Panel C), and the min counting procedure minus the number of counting errors (Panel D). For the latter, score is adjusted based on the number of problems solved with counting. The maximum score of 6 indicates that when the child used counting to problem solve, they always used the min procedure and never committed an error.
