Test 2 Flashcards
The focusing of light waves from objects of different distances directly on the retina
Accommodation
A visual problem in which the light waves from nearby objects are focused behind the retina during the images of these objects
farsightedness
A theory of color vision which assumes that there are three types of cones each activated only by wavelength ranges of light corresponding roughly to blue green and red
Trichromatic Theory
The brains you some knowledge of beliefs and expectations to interpret sensory information
Top down processing
The Gestalt perceptual organizational principle that the brain completes incomplete figure stuff for meaningful objects
Closure
Are sensitivity to unchanging and repetitive stimuli disappears every time
Sensory adaptation
Hearing loss created by damage to one of the structures in the ear responsible for caring the auditory information to the inner ear
Conduction deafness
The number of times a waveform cycles in one sec
Frequency
The perceived magnitude of a stimulus is equal to its actual physical intensity raised to a constant power and this constant power is different for each type of sensory judgment
Steavens power law
The minimum difference between two sensory stimuli detected 50% of the time
Difference threshold
Wavelengths of light that when added together produce white
Complementary colors
A theory of pitch perception which assumes that the frequency of the soundwave by the firing rate of the entire basilar membrane
Frequency theory
A line or shape that is perceived to be present but does not really exist the brain creates it during perception
Subjunctive contour
The perceptual stability of the size shape brightness and color for Familiar objects varying distances different angles and under different lighting conditions
Perceptual constancy
The process by which the rods and cones through internal chemical changes become more and more sensitive to light in dim light conditions
Dark adaptation
The amount of energy in a sensory stimulus is detected 50% of the time is called the
Absolute threshold
If a person is using a very strict criterion for a single detection task the false alarm rate will be blank and the miss rate will be blank
Low, high
According to Webbers law if C equals 1/50 then the difference threshold for a standard stimulus of 100 units would be
Two
Red wavelengths of light are blank and Violet wavelengths of light are blank
Long, short
The rods in the retina are responsible for blank vision and the cones are responsible for blank vision
Dim light, color
According to the opponent process theory of color vision if you stared at a blue circle for a while and then looked at a white surface you would see a circular blank after image
Yellow
Transduction of sound waves into neural impulses is performed by the
Hair cells in the basilar membrane
The best explanation for how we perceive low pitches is the blank Theory and the best explanation for how we perceive high pitches is the blank theory
Frequency, place
Perceptual set a good example of
Top down processing
Which of the following is a binocular depth cue
Retinal disparity
What is the purpose of transduction
Translating physical energy into neural signals that the brain can understand
Damage to the hair cells in the Coachlea causes blank deafness and blank occurs when light waves from distant objects come into focus in front of the retina
Nerve, nearsightedness
Even though the image of your dog on your retina changes as your dog runs to fetch a stick you do not perceive your dog is getting smaller which process of perception explains this phenomenon
Perceptual constancy
Perceiving either a vase or two facial silhouettes looking at each other was used to illustrate the gestalt principle of blank perceiving two ambiguous characters numerically as 13 or alphabetically as B was used to illustrate blank
Figure and ground, contextual effects
Although Henry’s watchband was bothering him when he first put it on a short while later he did not even notice he was wearing it this illustrates blank
Sensory adaptation
A classical conditioning procedure in which the condition stimulus proceeds the unconditioned stimulus but the two stimuli do not occur together
Trace conditioning
Hey stimulus that games it’s reinforcing property through learning
Secondary reinforcer
In operant conditioning giving operant response in the presence of stimuli similar to discriminative stimulus
Stimulus generalization
The stimulus that comes to elicit a new response in classical conditioning
Conditioned stimulus
The finding that operand responses reinforced I’m partial schedules are more resistant to extinction than those reinforce on a continuous schedule
Partial reinforcement effect
