| Weber's law | juat noticeable difference of a stimulus is a constant proportion of the original intensity of the stimulus |
| absolute threshold | the intensity of a stimulus that allows an organism to just barely detect it |
| blindsight | a condition brought on by damage to the visual cortex, in which people are unable to consciously report on visual stimuli but nevertheless are able to accurately answer questions about what they are seeing |
| difference threshold | the change in a stimulus that can just barely be detected by the organism |
| subliminal stimuli | stimuli that are below the absolute threshold and of which we are not conscious |
