q3 i? On the addition choice task, second graders with MLD made at least 2.5 times more counting errors than peers, and MLD children committed more errors than any other group. → Geary 2012

q3 · i? · associational · r2

Multilevel analysis of counting errors on the choice addition task in second through fourth grade. The study reports the printed contrast for second grade and notes across-grade improvements in counting accuracy and fewer retrieval errors for children with MLD.

"Second graders with MLD made at least 2.5 times more counting errors, whether using their fingers or not, as children in the other groups (|t|s > 2.25, ps<.05); the children in the latter groups did not differ (|t|s < 1)."

Discussion¶

Related Claims¶

• Counting-string intrusion errors are as common in LA-Severe Fact Retrieval children as in children with MLD, but decline across grades only for the MLD group — related
• After controlling for domain-general abilities and reading, MLD children show deficits on all mathematical cognition tasks while LA-Severe children show a specific counting-string intrusion deficit — related
• Children with mathematical learning disabilities use finger counting more often and switch to memory-based strategies later than typically developing peers — related
