Document Summary
a: method of constant stimuli, method of estimation, method of limit, method of adjustment. Method of constant stimuli where you have stimuli such as light with different intensity at fixed value. Randomly present the stimuli to the participant in repetitive manner by keep coming back to same intensity and asked them if they see it or not every time it"s shown. Through this data, for each level of intensity, could calculate probability of that person to yes, from which derive a curve with low intensity with low probability & high intensity with high probability. retina (back of eye) first stage of vision processing. 5 ways of light can work: absorbed, diffracted, reflected, transmitted, or refracted: Absorbed: energy (e. g. light) is taken up by some substance and not transmitted at all: e. g. room w/ dust room (light in) will be reduced in brightness as opposed to when it 1st enter that room, e. g.
