Hearing
This part of the ear changes vibrations into nerve signals
Cochlea
Taste and smell are known as these types of senses
chemical senses
The group of senses including touch and balance
somesthesis
How does vision begin?
Light enters the eye
Any physical energy (light waves, sound waves, chemical molecules, pressure) that activates sensory receptors
Stimuli
These tiny cells inside the cochlea detect sound vibrations
hair cells
The sense of smell is also called this
olfaction
This system controls balance
Vestibular system
What does the pupil do?
controls how much light enters the eye
images that exploit the brain’s shortcuts, cognitive biases, and sensory processing limitations
optical illusions
Hearing loss caused by damage to the auditory nerve or cochlea
sensorineural deafness
DAILY DOUBLE: Receptors for taste are located here
taste buds
Pain mainly serves this purpose
protection/warning of danger
What does the lens do?
Focuses the light
“Can I detect it at all?” Threshold
Absolute
Hearing loss caused by problems in the outer or middle ear.
conduction deafness
Food tastes bland when this sense is blocked
Smell
Known as a "sixth sense"...think about athletics
balance
DAILY DOUBLE: What nerve is connected to the eye?
Optic nerve
“Can I tell it changed?” Threshold
Difference
This nerve carries sound information to the brain.
auditory nerve
Why do restaurants and food companies focus heavily on smell? Think about the % of flavor smell accounts for.
Smell accounts for 70-90% of flavor.
This sense helps you know body position without looking
kinesthesis
What is it called when the brain combines images from both eyes to create one image and allow depth perception. (Thumbs up)
Binocular fusion
The stronger the stimulus, the bigger the change needed to notice a difference.
