sensation - CORRECT ANSWERS ✔✔the process
through which the senses pick up visual, auditory, and
other sensory stimuli and transmit them to the brain
perception - CORRECT ANSWERS ✔✔the process by
which the brain actively organizes and interprets sensory
information
absolute threshold - CORRECT ANSWERS ✔✔the
minimum amount of sensory stimulation that can be
detected 50% of the time
difference threshold - CORRECT ANSWERS ✔✔a
measure of the smallest increase or decrease in a
physical stimulus that is required to produce a difference
in sensation that is noticeable 50% of the time
cornea - CORRECT ANSWERS ✔✔the tough,
transparent layer that covers the front of the eye and

light
Cones - CORRECT ANSWERS ✔✔The light-sensitive
receptor cells in the retina that enable humans to see
color and fine detail in adequate light but do not function
in very dim light
optic chiasm - CORRECT ANSWERS ✔✔where the two
optic nerves come together and where some of their
nerve fibers cross to the other side of the brain
myopia - CORRECT ANSWERS ✔✔far items are
blurred (near-sighted)
