Sensory and perception
Eye
Sight
Ear
Theories
100
The process of detecting external events by sense organs and turning those events into neural signal
What is sensation
100
opening in the center of the eye that lets light in
What is pupil
100
photo receptors that are sensitive to the different wavelengths of light that we perceive as color
What are cones
100
conducts sound waves to eardrum
What is the auditory canal
100
Theory that maintains that color vision is determined by three different cone types that are sensitive to short, medium, and long wavelengths of light
What is trichromatic theory
200
Involves attending to, organizing and interpreting stimuli that we sense.
What is perception
200
colored area containing muscles that regulate the size of the pupil
What is iris
200
photo receptors that occupy peripheral regions of the retina that are highly sensitive under low light conditions
What are rods
200
flexible outer ear flap of the ear, which channels sound waves into the ear canal
What is the pinna
200
theory that states that we perceive color in terms of opposite ends of the spectrum; red to green, yellow to blue, and white to black
What is opponent process theory
300
The minimum amount of energy or quantity of a stimulus required for it to be reliably detected at least 50% of the time.
What is absolute threshold
300
curved transparent dome that protects the eye and helps bend incoming light
What is cornea
300
the process by which rods and cones become increasingly sensitive to light under low levels of illumination. Takes about 20 minutes
What is dark adaptation
300
membrane that vibrates in response to sound waves
What is eardrum
300
theory that states how we perceive pitch is based on location along the. basilar membrane that sound stimulates
What is place theory of hearing
400
Perception below consciousness
What is subliminal perception.
400
transparent disk that focuses light rays onto the retina
What is lens
400
vision cells that respond selectively to simple and specific aspects of a stimulus such as angles and edges.
What are feature detection cells
400
moveable bones of the middle ear
What are the ossicles
400
Theory that states the perception of pitch is related to the frequency at which the basilar membrane vibrates.
What is frequency theory
500
The reduction of activity in sensory receptors with repeated exposure to a stimulus.
What is sensory adaptation
500
innermost layer of the eye where incoming light is converted into nerve impulses. The part of this where light rays are most sharply focused is
What is retina and fovea
500
Part of the temporal lobe where object recognition occurs
What is the ventral stream
500
fluid-filled membrane that is coiled in a snail like shape and contains the structures that convert sound into neural impulses
What is the cochlea
500
Depth cues, list them and give example
What is linear perspective, interposition, light and shadow, texture gradient, height in plane, relative size
