Difficulty estimating quantity linked to math learning disability – 2
Narrator: This is NIH Health Matters. I’m Joe Balintfy. In a recent study researchers compared children's ability to estimate quantity with their level of mathematics achievement. Dr. Kathy Mann Koepke, a staff scientist at NIH, explains how researchers used a computer screen…
Koepke: … to quickly, very briefly for 200 milliseconds, flash colored dots of different sizes and colors, and groupings, to measure the participant's ability to number discriminate.
Narrator: She says children with math learning disability or dyscalculia had significantly higher Weber scores, suggesting that problems with the approximate number system underlie math difficulties for children with dyscalculia.
