PSY312H5 Lecture Notes - Lecture 5: Optic Chiasm, Inner Ear, Photosensitivity
Document Summary
Feb 24th lecture + postings (not tested on supplementary readings) Vison: a particular wavelength hits your retina and stimulates a very specific response. Perception: how do we know that we perceive a colour the same way, we"ve learned to interpret colours the same way. Cats have a keen sense of movement. If they couldn"t see for longer than three months after birth they would be blind. If you aren"t exposed to light at birth, you won"t perceive light (your brain won"t develop a perception, but you will have a working retina) Pathways never develop into allowing you to perceive things: this is the principal of transduction. This period seems to be the first several months: light is electromagnetic radiation, you can only detect a narrow band of radiation. Other types you are not likely to detect. You can detect electricity (wet your finger and stick it in a socket)
