主要有兩個論點敘述-執行控制功能(Executive Control Function, ECF)概念,如下:
A.ECF與較高層特定的認知功能有關,像是頓悟(insight)、意志(will)、抽象概念(abstraction)與判斷(judgement)等功能,這些功能大多仰賴額葉運作。此觀點指出因這些執行認知功能為習得技巧故可被直接測量,就如同記憶或語言功能一般。ECF損傷將導致這些能力喪失。
B.第二個論點強調執行功能的控制部分-執行功能負責控制複雜活動的實行。此觀點內涵主要有二:(1)ECF首先與非執行歷程交互作用。(2)只有當非執行歷程運作發生問題,ECF損傷才會明顯表現出來。此控制觀點雖不一定與強調高層認知能力的舊觀點相容,但它卻強調嶄新的觀點-額葉控制系統與其他歷程互動的動態關係。

What's the difference between EF and ECF?
回覆刪除Is ECF listed as a glossary?
They are referred as the same thing in this article. The paper discusses the EF impairments associated with the frontal leisions ,how executive function is assessed in clinical settings, and the linkage of executive function with functional outcome; also discusses challenges in designing treatments for executive dysfunction.
