sensing XOR robot supervene on a linearly
separable space of neural ac7va7ons? (StM:208) Logical Rela7ons • AND (A and B) • OR (A, B, or both A and B) • XOR (exclusive or; A or B, but NOT both) Truth Table Representa7on A F F T T B F T F T Change the representa7on •

structuring informa7on • Suppor7ng extended cogni7on • Hypothesis of cogni7ve impar7ality • Hypothesis of motor deference – XOR is not a linearly separable func7on – and because the mental states supervene on the brain
body system, not the neural ac7va7ons alone. • To unravel the workings of these embodied, embedded, and some7mes extended minds requires an unusual mix of neuroscience, computa7onal, dynamic and informa7on
