etardnow Posted October 30, 2013 Report Share Posted October 30, 2013 A picture from my psychology textbook, "In this computer-generated copy of the Twenty-third Psalm, each line of the typeface changes imperceptibly. How many lines are required for you to experience a just noticeable difference?" The difference threshold (or the just noticeable difference [jnd]) is the minimum difference a person can detect between any two stimuli half the time. That difference threshold increases with the size of the stimulus. Thus, if you add 1 ounce to a 10-ounce weight, you will detect the difference; add 1 ounce to a 100-ounce weight and you probably will not. I dont know why im uploading it lol.

etardnow Posted October 30, 2013 Author Report Share Posted October 30, 2013 Another interesting theory i have while reading. The wavelength of light is artificially altered by our brain due to its slow reaction in perceiving its stimulus. i dont know how this works but i dont think its a coincidence that purple(cosmic purple), the color of hppd, is at the one end of our visible spectrum.
