Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i? DD children matched controls on spatial symmetry and mental rotation accuracy but were slower on trail-making A and mental rotation. → Szucs Denes 2013
Evidence¶
Szucs Denes 2013¶
Szucs Denes, Devine Amy, Soltesz Fruzsina, Nobes Alison, Gabriel Florence. (2013). Developmental dyscalculia is related to visuo-spatial memory and inhibition impairment. Cortex, 49(10). https://doi.org/10.1016/j.cortex.2013.06.007
q3 · i? · associational · r2
In the case-control study, accuracy equaled between groups on the spatial symmetry and mental rotation tasks while solution times were longer in DD (mental rotation: DD 66.7 ± 4.4 sec vs Control 56.0 ± 3.5 sec; trail-making A: 58.3 ± 5.4 vs 41.3 ± 2.0 sec).
"The accurate performance on the symmetry and rotation tasks suggests that spatial skills were available to DD albeit at a slower speed than to controls."
