If we wish to advance modelling practices beyond its current state of play, we need to reconsider the very foundation models are based on. Models should be useful and easy to grasp for the human mind. This instrumental character of models implies that model quality must be ultimately grounded in our innate predispositions for acting. I have proposed that such faculties can be comprehended as activity modalities: objectivation, contextualization, spatialization, temporalization, stabilization, and transition (Taxén, 2009). The activity modalities can be seen as the brain’s way of integrating sensations arriving in various sensory modalities into a coordinated and purposeful action percept.
