Actionism is committed to the idea that perception is active, but not in the sense that it requires that one move. What is required is that one understand the relevance of movement to action, and that one knows what would happen if one were to move. Perception is active, according to the actionist, in the same way that thought is active. We exercise our sensorimotor understanding when we see.So, Noë doesn't think that perception requires movement, but he does think that perceiving is an activity of exploring the environment. But, then, how does one explore an environment without moving?
(Noë, 2010, p. 247).
According to the sensorimotor or, as I shall call it, actionist approach, perceiving is an activity of exploring the environment making use of this kind of knowledge of the sensory effects of movement.
