Document Summary
The process by which we receive, transform, transform, and process stimuli from the outside world to create sensory experiences of vision, touch, hearing, taste, smell, and so on. Smallest amount of stimulus we react to (50% of the time) Stimuli detected less than 50 percent of the time are considered below the absolute threshold. Stimuli that can be detected more o en are above the threshold. The minimal difference in the magnitude of energy needed for people to to detect a difference between two stimuli. The principle that the amount of change in a stimulus needed to detect a difference is given by a constant ratio or fraction, called a constant, of the original stimulus. Weber"s constant for noticing a difference in weights is about 1/50. The difference you can notice unless the weight were increased or reduced by 1/50*100g. Exposure to a constant stimulus can lead us to become habituated, or accustomed, to it.
