A mathematical theory of perception-in-action has been devised and investigated in many forms of controlled movement, and has been described in many different species of organism using the General Tau Theory. According to this theory, "tau information", or time-to-goal information is the fundamental percept in perception.
A fourth theory of perception in opposition to naive realism, enactivism, attempts to find a middle path between direct realist and indirect realist theories, positing that cognition is a process of dynamic interplay between an organism's sensory-motor capabilities and the environment it brings forth.
