Sensation and Perception Principles
To perceive together; two senses are sensed at the same time.
What is synesthesia?
This part of the eye is the ring of muscle that causes the pupil to change size.
What is the iris?
These are vibrations of molecules that travel through the air.
What are sound waves?
The process of chemical molecules being breathed in through the nose.
What is smell?
Objects that are darker may seem like they are farther away than objects that are lit.
What is light and shadow?
The transformation of stimulus energy to electrochemical energy of neural impulses.
What is transduction?
These specialized photoreceptors that work well in low light conditions.
What are rods?
This device converts sound into electrical signals that stimulate the auditory nerve.
What is a cochlear implant?
A condition 7/10 amputees have where they can still experience sensation where their amputated limb was.
What is Phantom Limb Syndrome?
What is parapsychology?
Centering one's attention on certain important elements of one's environment while other things blend into the background.
What is selective attention?
The Young Helmholtz Trichromatic Theory states that these three colors are responsible for the perception of color.
What are red, green, and blue?
Theory stating that one hears pitch based on how fast one's hair cells vibrate.
What is Frequency Theory?
What is the vestibular sense?
While moving, objects closer to one appear to zoom past one while objects farther away move slowly.
What is relative motion?
The principle in which, to be perceived as different, two stimuli have to differ by a constant minimum percentage (bigger stimuli require larger differences to be noticed).
What is Weber's Law?
Visible light falls between 400 and ___ nanometers.
What is 700?
This is the name of the outermost visible part of the ear that protrudes from one's head.
What is the pinna?
Spinal nerves acting as gates to let pain travel through the body and reach the brain.
What is the Gate Control Theory of Pain?
When objects overlap, the one that is partially covered seems to be farther away.
What is interposition?
Amazon, FedEx, and Beats are all examples of this perception principle.
What is subliminal sensation/persuasion?
After light hits the photoreceptors in the eye, chemical reactions activate these cells.
What are bipolar cells?
This effect is an illusion that takes place when vision and hearing interact with each other.
What is the McGurk Effect?
What is umami?
Being able to look at the world in three dimensions and being able to judge the distance of objects.
What is depth perception?
