Talking the Talk is Like Walking the Walk : A Computational

I describe an implemented computational model of verbal aspect that supports the proposition that the semantics of aspect is grounded in sensory-motor primitives. In this theory, aspectual expressions refer to schema-tized processes that recur in sensory-motor control (such as goal, periodicity, iteration, nal state, duration, and parameters such as force and eeort). This active model of aspect grounded in sensory-motor primitives is able to model cross-linguistic variation in aspectual expressions while avoiding some paradoxes and problems in model-theoretic and other traditional accounts.
