Document Summary

Sensation: stimulus and detection process, stimuli to touch to organ to nerve to brain and back.

Difference threshold is the difference between the individual stimuli the change in high and low sensitivities. We(cid:271)er"s law: magnitude of stimuli is proportional to the comparison of stimuli.

The active process of perception: bottom up: interpreting sensory information and assembling it, raw feeling to meaning.
