抑制狀態調節存在句中否定概念的處理：腦電位證據

// Inhibitory states modulate the processing of negated concepts in existential sentences. Evidence from ERPs

本研究透過結合Go/NoGo任務與否定句的ERP實驗，探討抑制控制狀態對存在性否定處理的影響｜結果顯示先前的抑制狀態（NoGo試次）提升早期注意力（P2波增強）並改變語義處理（N400波減弱），且影響集中於抑制相關腦區｜此外，維持否定概念增強了回應前的準備性腦活動，支持神經抑制機制調節否定處理的RIN假說。

// This study tested if inhibitory control states affect processing of existential negation using an ERP paradigm combining a Go/NoGo task and negated or affirmative sentences. Results showed that prior inhibitory states (NoGo trials) increased early attention (enhanced P2) and altered semantic processing (reduced N400-like negativity) for negated concepts, localized to inhibitory brain regions. Additionally, maintaining negated concepts increased preparatory brain activity before responding. These findings support the RIN hypothesis that neural inhibition mechanisms modulate negation processing.
