Two main types of dissociation can be considered in order to articulate action and abstraction. Vision for action and vision for perception are often described as dissociated systems at both anatomical and functional levels. Within this framework, abstraction should be specific to perceptual representation, whereas the action system would simply analyse the objective metric of space. By contrast, one may focus on dissociations within the action system. In this case, one will accept that action may involve abstract representations, at least during movement preparation. But a specific visuomotor level of processing can be described that appears to comply with the spatial properties of the relationship between the actor and the environment. This system would be specialized for fast movement guidance towards pre-defined goals. Such an automatic piloting system would thus be free of abstraction.
