The recent ChatGPT has changed our view of language generation.The present study reexamines the language generation and performance of ChatGPT based on the language generation theory of ECL(embodied cognitive linguistics),for the purpose of furthering the integration of linguistic research and artificial intelligence.Firstly,the present study reviews the three phases of the language generation technology of ChatGPT and its linguistic implications.Secondly,the present study holds that the daily language is the result of reality and cognition based on the language generation theory of ECL,specifically from reality to cognition and then to language.Thirdly,by examining the three phases of ChatGPT's language generation,the present study deems that its language generation follows a"language to language"pattern with little indirect involvement of cognition.Thus,though ChatGPT is empowered with great language generation ability,performance errors are bound to appear,such as falsity,confusion as well as nonsense.Finally,the present study considers the key to overcoming these performance errors is for ChatGPT to realize embodied cognition.
