PSYB51H3 Chapter Notes - Chapter 5: Monochromacy, Dichromacy, White Lion
Document Summary
Instead we see colour as our physical stimulus with a particular nervous system. In other words, the colours must go with the object (e. g. that rose looks red) and does not change dramatically (e. g. rose should remain red under the sun or shadow) With the l-cone is maximally sensitive at about 565nm, the m-cone can still detect the wavelength as well: therefore, the cone photoreceptors" spectral sensitivities overlap each other. Photopic referring to light intensities that are bright can activate the cone receptors and able to saturate the rod receptors meaning that to drives the rod receptors to their maximum responses. Scotopic referring to light intensities that are bright enough to stimulate the rod receptors but too dim to stimulate the cone receptors. Step 2: colour discrimination: since we know that we can detect wavelengths between 400 and 700nm, how will you detect lights of 450, 550 and.
