It tended to support the interactive activation theory on speech production, and the results verified the assumption of the research.

This article is a brief summary of speech production抯 research tradition and the main research materials in recent years in western countries.

The time course of lexical processing in speech production was discussed with two picture-naming paradigm experiments.

, and further- more into 16 kinds of corresponding “ecological languages” such as “self-sun-shading” etc.

This paper,after sensibly analizing the ecological construction form from construction noumenon form puts up shape feature,space adjustment and four sensible conceptional forms and sixteen corresponding ecological languages.
