Basic Principles
When you get used to a constant stimulus (ex. A beeping noise that starts off as annoying but then you don't mind it)
What is Sensory Adaptation?
Tightly-wound structure within the inner ear, whose fluids, when vibrated by the ossicles, are jostled, which causes ripples in the basilar membrane.
What is the Cochlea?
Color we experience (length of wave).
What is Hue?
The clear outer part of the eye's focusing system located at the front of the eye.
What is the Cornea?
There is an area of missing information in our field of vision known as the..?
What is the Blind Spot?
Information processing guided by higher mental processes; Perceptions are constructed based on experiences and expectations.
What is Top-Down Processing?
Monitors body's position and movement (semicircular canals in ear help keep balance)
What is the Vestibular Sense?
Distance from the peak of one light/sound wave to the next.
What is Wavelength?
A clear part of the eye behind the iris that helps to focus light, or an image, on the retina.
What is the Lens?
The largest sensory nerve of the eye. It carries impulses for sight from the retina to the brain.
What is the Optic Nerve?
Analysis in which sensory information is received and it travels to the brain.
What is Bottom-Up Processing?
A tone's experienced highness or lowness; depends on frequency.
What is Pitch?
Process by which the lens changes shape to focus near or far objects on the retina.
What is Accommodation?
The light-sensitive tissue at the back of the eye. It converts light into electrical impulses that are sent to the brain through the optic nerve.
What is the Retina?
A type of Receptor Cell which helps with color and daylight vision. It does not respond well to dim light, and is concentrated in the center of the Retina. It provides sharper and more detailed vision. (5-6.4 Million)
What are Cones?
Process by which sensory receptors and the nervous system receive & represent stimulus energies from the environment.
What is Sensation?
Number of complete wavelengths that pass a point in a given time.
What is Frequency?
Amount of energy in a light or sound wave which we perceive as brightness or loudness (heigh of wave)
What is Intensity?
The opening at the center of the iris. The iris adjusts the size of it and controls the amount of light that can enter the eye.
What is the Pupil?
A type of Receptor Cell which helps with peripheral and night vision (black & white vision). It does not respond well to bright light, and is more dense outside the Fovea. It provides better vision in low light. (100-125 Million)
What are Rods?
Process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events.
What is Perception?
States that the spinal cord contains a "gate" that blocks or allows pain signals to pass on to the brain; the gate is opened up by activity of pain signals traveling up small nerve fibers and is closed by activity in large fibers or by information coming from the brain.
What is the Gate-Control Theory?
Conversion of energy from one form to another.
What is Transduction?
The colored part of the eye made of muscle that constricts or dilates based on the amount of light entering the eye.
What is the Iris?
Located in the retina, responsible for sharp central vision.
What is the Fovea?
