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? The VWFA region of interest exhibited greater activation as a function of rate, but there was neither an effect of group nor a group x rate interaction. → Christodoulou JA 2014

q3 · i? · causal · r1
An a priori 10 mm sphere ROI at canonical VWFA coordinates was examined across rates and groups. The ROI showed greater activation as a function of rate (p<.0001) with no group effect and no group x rate interaction (p = .41).
"the putative visual word form area (VWFA; left fusiform gyrus) region of interest exhibited greater activation as a function of rate ( p,.0001), but there was neither an effect of group nor a group x rate interaction ( p = .41)"
Discussion¶
Related Claims¶
- 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 DD show greater brain activation than TD children in parietal, occipito-temporal and prefrontal regions during both addition and subtraction — related
- In-scanner sentence judgment accuracy declines with faster word presentation rates, and dyslexic readers' accuracy declines disproportionately across rates — related
- Group differences in activation are more extensive when behavioral performance is equated across groups, indicating they are not a consequence of worse performance — related
