the activation of the sense organs by a source of physical energy; EX: sensing a bright light, sound, or pinch

The sorting out, interpretation, analysis, and integration of stimulus involving the sense organs and brain (brain kicks in); EX: feeling the heat of a hot pepper

Energy that produces a response; EX: bright light causes you to squint

The minimum stimulation level an organism needs to sense a stimulus

a phenomenon in which the body adjusts to external stimuli over time, becoming less sensitive or responsive to that particular stimulus

belief that some people have knowledge of information that is not gained through the senses

the clear tissue in front of your eye, helps to protect your eye and filters out some UV light

a clear disk behind the iris, that bends light and focuses it for the retina to help see images clearly

the spot in the retina where the optic nerve connects, there are no light-sensitive cells, so this part of the retina cannot see

mental transfer of information from one person to another

medium (communicate with the dead) or finding lost people

predicting future events

gut feeling/feeling that something has happened

How well you can see what your not staring at

microscopic structures in the eye that help you see in the dark

Eyes Adapting to bright light

Eyes adapting to dark environment

Naturally occurring chemicals in the body that are secreted into the environment. These secretions produce a reaction in other members of the same species

a memory is triggered when one of the senses is stimulated. That memory is so memorable because it was surprising, unexpected, and/or unusual (songs, scent)
