結果

FDT與WCST-PE、WCST-NPE為正相關，與WCST-NCC為負相關。我以紅字表示，強調相關高於0.40的數值。

WCST-PE與FDT之alternating attention有中度相關(3次測量之相關係數>0.40)。依照之前文獻回顧結果，WCST-PE應為測驗cognitive flexibility之指標，但只有第3次之測量有顯著中度相關。

WCST-NPE與FDT之sustained attention有中度相關(3次測量之相關係數>0.44)。依照之前文獻回顧結果，WCST-NPE應為測驗ability of inhibition之指標，雖與ability of inhibition有中度相關，但只有第二次和第四次的測量之相關係數有超過0.45。
