In the present study, performance on a range of mathematical reasoning and number processing tasks was assessed across two syndrome groups for which numerical ability is under-researched: Fragile X syndrome and Down syndrome. Given the paucity of current research, it was unknown whether all aspects of arithmetic and number processing would be globally affected across groups or whether there would be syndrome specific proficiencies and deficiencies. Statistical analysis revealed that males with fragile X syndrome performed significantly worse on all tasks even when performance was compared to typically developing children of a similar developmental level. However, when performance was compared to children with Down syndrome differing profiles emerged, with greater weaknesses by the fragile X syndrome males on specific tasks requiring mental arithmetic and basic numeracy skills. The importance of using syndrome specific information in the assessment of math disabilities and the design of early educational interventions are discussed.
