Document Summary

Task today connects the physical and psychological word: psychophysics. Want to have an underlying reason to measure something. Duality between the soul and the body. Made a clear distinction between the world and the mental representation of the world. The world is not how we see it, nobody sees color the same way. Stimulus in the world ( distal), in the body (proximal) The perception we have is all about the proximal ( grid illusion) We change the perception of the stimulus. Fechner beliefs that the physical and the mental are functionally dependent relations. Physics says that two of the boxes are the same colour, the same luminants when we perceive. Can you tell the difference between things. If everything below you can hear, everything above you can ( e. g. ) When you get data like ( slide a. t) you go to 50 and that is the absolute threshold when they add chemical to get coffee hot even though its cold)
