Facts about the Ear and Eye
100
Light pass through this part which is surrounded by the iris
What is the Pupil?
100
This type of processing is guided by higher level mental processes based off of our experiences and expectations.
What is Top-Down processing?
100
The absolute minimum stimulation needed to detect a particular stimulus.
What is an absolute threshold?
100
a coiled, bony, that fluid-filled tube in the inner ear through which sound waves trigger nerve impulses.
What is a Cochlea?
100
Incoming vibrations cause the Cochlea Membrane
What is refer as the oval window?
200
Focuses incoming light rays into an image on the retina
What is lens?
200
This process helps us organize and interpret sensory information, which enables us to recognize meaningful objects and events
What is Perception?
200
This theory of predictions tells us how we detect a faint stimulus amid background noise.
What is the Signal Detection Theory?
200
The chamber between the eardrum and cochlea containing 3 tiny bones (hammer, anvil, and stirrup.
What is the middle ear?
200
What is known as a small Shaped tube?
What is Inner Ear?
300
A colored muscle that adjusts light intake
What is Iris?
300
This process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment.
What is Sensation?
300
Literally meaning “below threshold”, this means to be below one’s threshold for conscious awareness.
What is the meaning of subliminal?
300
The innermost part of the ear, containing the cochlea
What is the inner ear?
300
What transmit the eardrum vibrations?
What is Middle Ear?
400
Images are projected onto this?
What is retina?
400
Our diminishing sensitivity to an unchanging stimulus
What is sensory adaptation?
400
The minimum difference between two different stimuli required for detection 50% of the time, this also called the just noticeable difference.
What is the Difference Threshold?
400
The number of complete wavelengths that pass a joint in a given time
What is frequency?
400
What send s Neural Messages via the thalamus?
What is Auditory Cortex?
500
(worth 1,000 points)
The light passes through the cornea, pupil, and lens. The curvature and thickness of the lens change to bring either nearby or distant objects into focus on the retina...
What area consists of all 3 of these parts?
What is the Eye?
500
This type of processing begins with the sensory receptors and works its way up to the brains integration of sensory information.
What is Bottom-up processing?
500
This law says that to be perceived as different, two stimuli must differ by a constant minimum percentage.
What is Weber’s Law?
500
A tone’s experienced highness or lowness
What is pitch?
500
(worth 1,000 points)
The optic nerve connects to the brains visual cortex via the ____________
What is thalamus?
