Document Summary

The process by which our sensory receptors and rest of sensory nervous system receive info from the world and then transmit it throughout the rest of the nervous system. A process by which the brain then interprets the sensory information to make sense of the world. Interested in the study of the relationship between how big a sensation had to be and the perceptual sensation that rises from that. Magnitude of actual physical energy, and how much we actually think there is. Created subdiscipline of measurements and ways of creating this. How much stimulation is needed for you to know the stimulus is present. Eg. enter a room that is dark and turn on tiny light on dimmer, how much would you have to crank the light for the observer to detect the light. The amount of times you see a light - the absolute threshold.
