Dyscalculia-Math Challenged

[SimonTam]

Yes, most of the papers listed do mention children and arithmetic. This is probably due to the fact that higher forms of math have a foundation in the basic mathematical functions used in arithmetic. Also, learning disabilities are usually easier to determine and clarify in children. Most adults, who may have a learning disability but were never diagnosed with it, usually will develop compensatory behaviour that may affect experiments trying to quantify a disability.

Dyscalculia is a term referring to a wide range of life-long learning disabilities involving math. There is no single form of math disability, and difficulties vary from person to person and affect people differently in school and throughout life.
