Subclaims¶

q2 i? Lesion mapping of individuals with dysgraphia localized orthographic long-term memory deficits to either the left posterior inferior frontal region or left ventral temporal cortex. → Rapp 2016

q2 · i? · associational · r?

Voxel-based lesion-mapping analysis of 27 stroke survivors with dysgraphia, identified on behavioral profiles alone as having deficits affecting only orthographic long-term or working memory, plus 6 with both. The article reports "orthographic long-term memory deficits centered in either the left posterior inferior frontal region or left ventral temporal cortex." No effect size is printed.

"with orthographic long-term memory deficits centered in either the left posterior inferior frontal region or left ventral temporal cortex"

Discussion¶

Related Claims¶

• Orthographic working memory deficits in dysgraphia arise primarily from lesions of the left parietal cortex centered on the intraparietal sulcus
• Behavioral profiles alone can identify dysgraphia cases with deficits selectively affecting orthographic long-term memory or working memory
• Distinct neural substrates selectively support orthographic long-term memory and orthographic working memory in spelling — a broader claim this one bears on
• Lesion evidence links written-language processes to language, working memory, and other cognitive skills — related
