Living organisms are under permanent pressure to take decisions with an impact on their success. Such decisions require information, which can be formulated in the precise sense of Shannon information. Since information processing is costly for organisms, this creates an adaptive pressure for cognition to be as informationally parsimonious as possible. Combining information theory with the theory of reinforcement learning for modeling tasks, we present a number of quantitative analyses how the cognitive burden of an agent deriving from a task can be relieved by the environment and, more specifically, its embodiment, i.e. how the agent "controller" is linked to the environment, via perception (in principle, but not further considered here) and action (this paper's main focus). The methodology presented offers a path towards a formal and quantitative treatment of Paul's and Pfeifer's concept of morphological computation in particular and their envisaged larger picture of offloading of computation onto the environment dynamics in general. In particular, it offers additional evidence for the central importance of the embodiment for the success of cognition.
