Document Summary

After effect: an after effect is caused by distribution coding. Distribution coding is the process of a group of neurons enacting on one single orientation. When you look at something black, you use less photopigment and have less action potentials. The cells that were seeing the white part were working hard, and the ones that were seeing the black part had less to recover from. Aftereffects:- tilt after effect (line orientation): have a person adapt to a specific line orientation (diagonal), then show them a different line orientation (vertical), and then they report seeing the opposite diagonal direction. People misperceive vertical lines. happens because when you adapt to the tilted lines you tire out receptors a lot, the vertical receptors not very much, and for the opposite tilt, not at all. Don"t have to figure anything because we just respond to the appropriate variance, then wont have any dimensional ambiguity, because you are not staying in one place.
