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.
q2 i? In adults with DD, a significantly reduced Number Stroop effect during physical comparison indicates the numerical magnitude of digits produced less interference than in controls. → Liane Kaufmann 2020

q2 · i? · causal · r?
Review reports Rubinsten and Henik (2005) Number Stroop study: a "significantly reduced NSE was reported during physical comparison" in adults with DD, interpreted as reduced automatic activation of number magnitude. A similar reduced NSE occurs when TMS is applied over the right IPS in healthy participants.
"In adults with DD, a significantly reduced NSE was reported during physical comparison (Rubinsten & Henik, 2005) suggesting that the numerical magnitude of the digits led to less interference in adults with DD than in controls."
Discussion¶
Related Claims¶
- Adults with DD show deficient conceptual size processing with preserved physical size processing, supporting shared magnitude substrates — related
- Neuroimaging shows adults with DD exhibit stronger frontal activations during number semantics, reduced right parietal grey matter, and altered functional connectivity during non-symbolic magnitude comparison — related
- Children with developmental dyscalculia are more susceptible to task-irrelevant information than controls across five experiments — reports the opposite
- Non-symbolic magnitude processing shows mixed associations with inhibition measures — related
- Groups with reading difficulties perform significantly better than controls on the Stroop interference measure, and only math groups show set-shifting weakness — related
- Adults with DD show a smaller subitizing range and impaired enumeration of random sets across visual and tactile modalities — related
