Absolute threshold: a candle flame seen at 50km on a dark clear night, the tick of a clock 20 feet away, a drop of perfume in a six-room. 5ml of sugar in 7. 5l of water. house: a wing of a fly on your cheek, dropped. 1cm: as stimulus intensity increases, subjects" probability of responding to stimuli gradually increases. However, they won"t be able to detect the difference between a 900-gram weight and a 910-gram weight: as stimuli increases in magnitude, the jnd becomes larger. There would now be a difference in the lighting after being in complete darkness. Turns the switch again, and second bulb lights. The light is doubled, but it"s not twice as bright. Turns third bulb on, difference is barely noticeable.
