Vocab
The stimulation of the sense organs;
The senses collect information from stimuli in the environment and convert it to a signal that can travel to the brain
Sensation
Close objects are seen clearly, but distant objects appear blurry
Nearsightedness
Specialized visual receptors that play a key role in daytime vision and color vision
Cones
The visible portion of the outer ear; collects sound waves and transmits them toward the eardrum
Pinna
The 5 primary tastes
Salty, sweet, sour, bitter, umami
Process by which we select, organize, and interpret sensory information to recognize meaningful objects and events
Perception
Distant objects are seen clearly, but close objects are blurry
Farsightedness
Specialized visual receptors that play a key role in night vision and peripheral vision
Rods
Fluid-filled, coiled tunnel that contains the receptors for hearing
Cochlea
The sensory system for taste
Gustatory System
Progression from individual elements to the whole; Takes in raw sensory information from the environment and processes it without relying on prior knowledge or expectations
Bottom-Up Processing
Visual image that persists after a stimulus is removed
Afterimage
The opening in the center of the iris that helps regulate the amount of light that enters the eye
Pupil
The perception of pitch corresponds to the vibration of different portions of the basilar membrane; Hair cells at various locations respond independently
Place Theory
The sensory system for smell
Olfactory System
Progression from the whole to the elements; Starts with a larger object, concept, or idea before working our way towards more detailed information. Uses past experiences, context, and expectations
Top-Down Processing
This theory of color vision asserts that the human eye as three types of receptors with different sensitivities to different light wavelengths.
Says that red, green, and blue can be combined to create all colors of light
Trichromatic Theory of Color Vision
The neural tissue lining the back surface of the eye that absorbs light, processes images, and sends visual information to the brain
Retina
Perception of pitch corresponds to the rate at which the entire basilar membrane vibrates
Frequency Theory
Physical stimuli of this system is mechanical, thermal, and chemical energy that comes in contact with the skin
Tactile System
Failure to see fully visible objects or events in a visual display because one’s attention is focused elsewhere
Inattentional Blindness
The spot in the center of the retina that contains only cones, where visual acuity is the greatest
Fovea
Transparent structure that brings rays of light to a focus on the retina; changes shape to alter visual focus on near or far objects
Lens
Name the 3 ossicles
Hammer, anvil, stirrup
OR
Malleus, incus, stapes
The only sensory system that is not routed through the thalamus before the rest of the cortex
Olfactory System
