To explore how linguistic processes relate to brain mechanisms which integrate action and perception, we have developed a new kind of semantic representation, SemRep, and a system called Template Construction Grammar (TCG) in which constructions compete and cooperate to cover the SemRep to produce a description of a visual scene. The modeling is complemented by studying time-locked data on eye movements and verbal output as subjects describe visual scenes. The results support (1) the presence of a critical threshold for readout of assembled constructions which distinguishes a fragmentary description style from the style that favors grammatically correct and complete utterances
