PSY 110 Exam 3 (Illinois State University)
Questions With Correct Answers
sensation - CORRECT ANSWER✔✔-the process through which the
| | | | | | | |
senses pick up visual, auditory, and other sensory stimuli and transmit
| | | | | | | | | | |
them to the brain
| | |
perception - CORRECT ANSWER✔✔-the process by which the brain
| | | | | | | | |
actively organizes and interprets sensory information
| | | | |
absolute threshold - CORRECT ANSWER✔✔-the minimum amount of
| | | | | | | |
sensory stimulation that can be detected 50% of the time
| | | | | | | | |
difference threshold - CORRECT ANSWER✔✔-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 ANSWER✔✔-the tough, transparent layer that covers
| | | | | | | |
the front of the eye and bends light rays inward through the pupil
| | | | | | | | | | | | |
,lens - CORRECT ANSWER✔✔-the transparent disk-shaped structure
| | | | | | |
behind the iris and the pupil that changes shape as it focuses on objects
| | | | | | | | | | | | | |
at varying distances
| |
retina - CORRECT ANSWER✔✔-the layer of tissue that is located on the
| | | | | | | | | | | |
inner surface of the eyeball and contains the sensory receptors for
| | | | | | | | | | |
vision
fovea - CORRECT ANSWER✔✔-a small area at the center of the retina
| | | | | | | | | | | |
that provides the clearest and sharpest vision because it has the largest
| | | | | | | | | | | |
concentration of cones | |
optic nerve - CORRECT ANSWER✔✔-the nerve that carries visual
| | | | | | | | |
information from each retina to both sides of the brain | | | | | | | | |
blind spot - CORRECT ANSWER✔✔-the point in each retina where there
| | | | | | | | | | |
are no rods or cones because the cable of ganglion cells is extending
| | | | | | | | | | | | |
through the retinal wall | | |
iris - CORRECT ANSWER✔✔-the colored part of the eye that controls
| | | | | | | | | | |
the pupil |
pupil - CORRECT ANSWER✔✔-small opening that omits light
| | | | | | |
, Rods - CORRECT ANSWER✔✔-The light-sensitive receptor cells in the
| | | | | | | | |
retina that look like slender cylinders and allow the eye to respond to as
| | | | | | | | | | | | | |
few as five photons of light
| | | | |
Cones - CORRECT ANSWER✔✔-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 ANSWER✔✔-where the two optic nerves come
| | | | | | | | | |
together and where some of their nerve fibers cross to the other side of
| | | | | | | | | | | | | |
the brain
|
myopia - CORRECT ANSWER✔✔-far items are blurred (near-sighted)
| | | | | | |
hyperopia - CORRECT ANSWER✔✔-near items are blurred (far-sighted)
| | | | | | |
each cone is sensitive to different colors, blue, green, or red - CORRECT
| | | | | | | | | | | | |
ANSWER✔✔-color sensitivity |
1. hue - specific color perceived
| | | | | |
2. brightness - intensity of the light energy that is perceived and
| | | | | | | | | | | |
corresponds with the amplitude | | | |
3. saturation - purity of a color - CORRECT ANSWER✔✔-What are the
| | | | | | | | | | | |
three properties of light
| | |
