Basic Sensation
This is the process of detecting physical energy from the environment.
What is sensation?
The structure that focuses light onto the retina.
What is the lens?
Inability to recognize faces.
What is prosopagnosia?
The height of a sound wave that determines loudness.
What is amplitude?
Using prior knowledge to interpret sensory information.
What is top-down processing?
The minimum amount of stimulus energy needed to detect a stimulus 50% of the time.
What is absolute threshold?
This part of the eye has the sharpest vision.
What is the fovea?
This condition causes a person to lose part of their visual field, often due to damage where the optic nerve connects to the eye.
What is the blind spot?
The distance between sound wave peaks.
What is wavelength?
Failing to notice a rubber duck while focusing on counting passes.
What is inattentional blindness?
The smallest detectable difference between two stimuli.
What is just-noticeable difference?
These cells help you see in dim light.
What are rods?
Trouble seeing far away objects clearly.
What is nearsightedness?
This theory explains pitch by where the basilar membrane vibrates.
What is place theory?
Focusing on one voice in a noisy room.
What is selective attention?
This explains why Samira stops noticing her perfume after a few minutes.
What is sensory adaptation?
The blind spot occurs because of this structure leaving the eye.
What is the optic nerve?
Seeing a green image after staring at red is explained by this theory (afterimages).
What is opponent process theory?
Hearing loss caused by damage to hair cells in the cochlea.
What is sensorineural deafness?
A mental framework for organizing information.
What is a schema?
Seeing colors when hearing sounds is an example of this phenomenon.
What is synesthesia?
This theory explains color vision using red, green, and blue cones.
What is trichromatic theory?
This condition causes difficulty seeing nearby objects clearly because the eyeball is too short, causing images to focus behind the retina.
What is farsightedness?
The brain’s ability to determine where a sound is coming from.
What is sound localization?
When you hear your name across a crowded room.
What is the cocktail party effect?
