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? Individuals with dysgraphia were identified, on the basis of behavioral profiles alone, as having deficits affecting only orthographic long-term memory or only orthographic working memory, with others affected in both. → Rapp 2016

Rapp, Brenda; Purcell, Jeremy; Hillis, Argye; Capasso, Rita; Miceli, Gabriele. (2016). Neural bases of orthographic long-term memory and working memory in dysgraphia. BRAIN. https://doi.org/10.1093/brain/awv348
q2 · i? · associational · r1
Participant-classification component of the lesion-mapping study: 27 stroke survivors with dysgraphia were identified via behavioral profiles alone as having deficits affecting only one process, plus 6 with deficits affecting both sets of processes. The article prints these counts but no effect sizes.
"27 individuals with dysgraphia subsequent to stroke who were identified, on the basis of behavioral profiles alone, as suffering from deficits only affecting either orthographic long-term or working memory, as well as 6 other individuals with deficits affecting both sets of processes"
Discussion¶
Related Claims¶
- Orthographic long-term memory deficits in dysgraphia are centered in the left posterior inferior frontal region or left ventral temporal cortex
- Orthographic working memory deficits in dysgraphia arise primarily from lesions of the left parietal cortex centered on the intraparietal sulcus
- Distinct neural substrates selectively support orthographic long-term memory and orthographic working memory in spelling — related
- Lesion evidence links written-language processes to language, working memory, and other cognitive skills — related
