從認知語言學的角度來看，網絡四字格新詞的形成机制中充滿了中國式的認知方式。本文以認知語言學爲理論基礎，分析了中國網絡四字格新詞形成中的認知机制，在充分解釋的基礎上探尋了背后的當代中國的社會心理背景。 首先，隱喩指向經驗生活到槪念的認知途徑，網絡四字格新詞的形成過程體現出當代中國人對經驗社會的固有成見。網絡四字成語的産生，或反映了現代中國人對公共机構的公信力普遍缺乏信任；或反映了現代中國人挑戰傳統思維方式追求個性解放的認知變化。網絡四字格新詞旣有傳統漢語認知心理的繼承，又體現了現代中國人因社會轉型而引發的調侃、嘲弄地對待客觀世界的心態。 其次，類比指向從一個舊槪念到一個新槪念的認知途徑，體現在網絡四字格新詞之間的形式相似之上。某些網絡四字格新詞體現出的縮寫特征，不僅符合古人創造四字成語時追求生動簡潔的心理特征，而且反映出網絡時代交流求快的心理特点，滿足了網絡時代求新求異的需求。
