跨認知評估的共同變異可預測失語症的語言結局：初步研究

// Shared Variance Across Cognitive Assessments Predicts Language Outcomes in Aphasia: A Preliminary Study

17名慢性失語症與21名對照，分析出6項成分，顯示測驗間冗餘｜視覺空間處理速度與聽覺定向注意（注意力方向）預測較輕失語與更佳句子理解；視覺持續注意強則與失語更嚴重相關｜載荷最高的單一任務可預測句子理解但非失語嚴重度，建議精簡評估以利復健鎖定

// The study examined whether common cognitive tests share variance and whether the resulting components predict aphasia severity and sentence comprehension. Seventeen adults with chronic aphasia and 21 controls completed multiple attention and cognitive batteries; principal component analysis and regressions identified six components and related them to language outcomes. Subtests tended to cluster by battery (indicating redundancy); visuospatial processing speed and auditory orienting attention predicted milder aphasia and more efficient sentence comprehension, while greater visual-sustained attention was linked to more severe aphasia. Single tasks with the highest loadings predicted sentence comprehension but not aphasia severity, suggesting assessments can be streamlined to reduce redundancy and better target rehabilitation.
