Grush (2007; 2009) has proposed a detailed implementation of the disposition theory in terms of neural information processing. The proposal involves more mathematics than is appropriate here, and so a quick qualitative description will have to suffice (for more detail, see Grush 2007; 2009). The basic idea is that relevant cortical areas learn sets of basis functions which, to put it very roughly, encode equivalence classes of combinations of sensory and postural signals (for discussion, see Pouget et al. 2002). For example, many combinations of eye orientation and location of stimulation on the retina correspond to a visual stimulus that is directly in front of the head. Sorting such bodily postural information (not just eye orientation, but any postural information that affects sensation, which is most) and sensory condition pairs into useful equivalence classes is the first half of the job.
