Abstract
Embodied cognition suggests that complex cognitive traits can only arise
when agents have a body situated in the world. The aspects of embodiment and
situatedness are being discussed here from the perspective of linear systems theory.
This perspective treats bodies as dynamic, temporally variable entities, which can be
extended (or curtailed) at their boundaries. We show how acting agents can, for
example, actively extend their body for some time by incorporating predictably
behaving parts of the world and how this affects the transfer functions. We suggest
that primates have mastered this to a large degree increasingly splitting their world
into predictable and unpredictable entities. We argue that temporary body extension
may have been instrumental in paving the route for the development higher cognitive
complexity as it is reliably widening the cause-effect horizon about the actions of the
agent. A first robot experiment is sketched to support these ideas.
We continue discussing the concept of Object-Action Complexes (OACs) introduced
by the European PACO-PLUS consortium to emphasize the notion that for a cognitive
agent objects and actions are inseparably intertwined. In another robot experiment we
devise a semi-supervised procedure using the OAC-concept to demonstrate how an
agent can acquire knowledge about its world. Here the notion of predicting changes
fundamentally underlies the implemented procedure and we try to show how this
concept can be used to improve the robot’s inner model and behaviour.
Hence, in this article we have tried to show how predictability can be used to augment
the agent’s body and to acquire knowledge about the external world, possibly leading
to more advanced cognitive traits.
