Information processing guided by higher-level mental prcesses, as when we construct perceptions drawing on our experience and expections.
What is top-down processing?
100
The deminsion of color that is determined by the wavelength of light.
What is hue?
100
Nerve cells in the brain that respond to specific features of the stimulus, such as shape, angle, or movement.
What are feature detectors?
100
Theory that the retina contains 3 different color receptors-which when stimulated in combination can produce the perception of any color.
What is the Young-Helmholtz Trichromatic Theory?
100
Process by which our sensory receptors and nervous system recieve stimulus from our environment.
What is sensation?
200
Our awareness of faint stimuli illustrates our...
What is absolute threshold?
200
High frequency with bluish colors, high pitched sounds and low frequency with reddish colors, low pitched sounds.
What is the difference between short and long wavelengths?
200
Cells in the cortical ares that respond to more complex patterns.
What are super cell clusters?
200
Theory that opposing retinal processes enable color vision.
What is Opponent Process Theory?
200
The lens focuses the rays by changing its curvature in a process called
What is accomodation?
300
The principle that, to be percieved as different, two stimuli must differ by a constant minimum percentage
What is Weber's Law?
300
Name at least 5 different parts of the eye.
What is the Pupil, lens, Iris, cornea, retina, fovea, blind spot, and optic nerve?
300
Damage to this region, you could recognize forms and objects, but not faces.
What is the temporal lobe?
300
Defect that is genetically sex-linked.
What is color defect?
300
Bright colors, loud sounds and dull colors, soft sounds.
What is the difference between great and small amplitude?
400
Give an example of subliminal persuasion. (Doesn't need to be in the form of a question)
Advertising, etc.
400
Retinal receptor cells that are concentrated near the center of the retina and function in daylight.
What are cones?
400
The 4 subdimensions in parallel processing.
What is color, movement, form, and depth?
400
Most color deficient people aren't color blind, but simply lack one or both of these cones.
What are red and green cones?
400
The minimum difference between 2 stimuli required for detection 50% of the time.
What is difference threshold?
500
Our diminished sensitivity to constant or routine odors, sounds, and touches, to focus our attention on information changes in stimulation.
What is sensory adaptation?
500
Explain the uses of at least 2 parts of the eye. (Doesn't need to be in the form of a question)
Blind spot- Optic nerve leaves the eye; Optic nerve- Nerve that caries neural impulses from the eye to the brain; Retina- Light sensitive inner surface that begin the processing of visual information.
500
Give at least 3 characteristics of rods. (Doesn't need to be in the form of a question.)
Number- 120 million; Location in Retina- periphery; High sensitivity; no color sensitivity; no detail sensitivity.
500
Opponent processes explain this type of effect.
What is the afterimage affect?
500
The activation, often unconciously, of certain associations, thus pre-disposing one's perception, memory, or response.
