Basics of Sensation | Vision | More Vision | Hearing | Other Senses |
---|---|---|---|---|
What is perception?
The process of making our sensations meaningful.
|
What are light waves?
The stimulus energy of vision.
|
What is the wave height (amplitude)?
This determines how bright a color appears.
|
What is the wavelength?
Determines the pitch of a sound.
|
What is the gate-control theory?
The dominant theory of pain that believes pain signals are either blocked or allowed to pass.
|
What is transduction?
The transformation of a stimulus energy (such as light waves) into a neural impulse.
|
What is the wavelength?
This determines the color of a something.
|
What is the Young-Helmholtz trichromatic theory?
The theory of color that relies on our red, green, and blue receptors.
|
What is the ear drum?
Part of the ear that sound waves initially come in contact with that sends a chain reaction amplifying them.
|
What is the vestibular sense?
Our inner ear gives us this sense of balance.
|
What is top-down processing?
Using previous experience and expectations to process sensory information.
|
What is the iris?
The muscle that controls how much light passes through the pupil.
|
What is shape constancy?
The reason we still perceive a door as a rectangle even if the actual image you see is not a rectangle (i.e., open door).
|
What is the cochlea?
Part of the ear that contains hair cells, which receive sound waves.
|
What is umami?
Receptor that detects proteins in food.
|
What is an absolute threshold?
The point at which you hear a sound 50% of the time.
|
What are cones?
The fovea contains more of these light receptors which allow us to see color.
|
What are feature detectors?
Neurons in our visual cortex that allow us to perceive lines, shapes, movement, etc.
|
What is sensorineural hearing loss?
The most common type of deafness caused by damage to the hair cells or nerve cells.
|
What is the sense of smell?
The only sense that is not relayed through the thalamus before being perceived.
|
What are context effects?
When the situation affects your perception.
|
What are monocular cues?
Depth cues that do not rely on having 2 eyes (e.g., interposition, linear perspective).
|
What is retinal disparity?
The ability to see 3D close-up because of this binocular cue.
|
What is place theory?
Theory that links sound heard to the location on the cochlea that it stimulates.
|
What is embodied cognition?
When our sensations and emotions affect our perception.
