Sensation
The process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment.
Top-down processing?
information processing where we construct perceptions drawing on our experiences and expectations
Neurons that fire in response to specific edges, lines, angles and movements are called what?
a.Rods
b. Cones
c.Ganglion cells
d.Feature detectors
e.Bipolar cells
d.Feature detectors
What does Weber's law determine?
Tyshane went swimming with friends who did not want to get into the pool because the water felt cold. Tyshane jumped in and after a few minutes declared, "It was cold when I first got in, but now my body is used to it. Come on in!" Tyshane's body became used to the warer due to.....
Sensory adaption
Transduction
Conversion of stimulus energies into neural impulses
Place theory?
pitch is linked to the place where the cochleas membrane is stimulated
Gate-Control theory refers to
a.which sensory impulses are transmitted first from each sense
b.which pain messages are perceived
c.interfering sound waves, causing some waves to be undetected
d.the gate at the optic chasm controlling the destination hemisphere for visual information from each eye
b.which pain messages are perceived
Difference between amplitude and frequency in the context of sound waves?
Amplitude = height of sound waves
Frequency = how frequently the sound waves pass a certain point
Natialia is washing her hands and adjusts the faucet handle until the water feels just slightly hotter than it did before. Natalia's adjustment until she feels a difference is an example of......
Difference threshold
Perceptual Set
A mental predisposition to perceive one thing and not another
Frequency theory?
we sense pitch because of the rate of nerve impulses travelling up the auditory nerve matches the frequency of a tone
The cochlea is responsible for
a.protection the surface of the eye
b.transmitting vibrations received by the eardrum to the hammer, anvil, and stirrup
c.transforming vibrations into neural signals
d.sending messages to the brain about orientation of the body and head
c.transforming vibrations into neural signals
What is the purpose of the Iris?
To allow light into the eye
A teacher used distortion goggles, which shifted the wearer's gaze 20 degrees, to demonstrate an altered perception. A student wearing the goggles initially bumped into desks and chairs while walking. After 30 minutes the student was able to smoothly avoid obstacles, illustrating the concept of.....
Perceptual adaptation
Binocular Cues
Depth cues, such as retinal disparity, that depend on the use of two eyes
Opponent-processing theory
opposite retinal processes enable color vision.
What function does the retina serve?
a. contains the visual receptor cells that transform light into neural impulses
b.focuses light coming in the eye through the lens
c.determines how much light is let into the eye
a.contains the visual receptor cells that transform light into neural impulses
Which perception process are the hammer,anvil and stirrup involved with?
Transmitting sound waves to the cochlea
Sarene had a cochlear implant in both ears because of hearing loss. What type of hearing loss did Sarene most likely have?
Sensorineural Hearing Loss
Kinesthesia
The system fore sensing the position and movement of individual body parts
Trichromatic Theory
retina contains three color receptors - red, blue and green. Which allows us to see color
What behavior would be difficult without our vestibular sense?
a.intergrating what we see and hear
b.writing our name
c.walking in a straight line with our eyes closed
d.reporting the exact position and orientation of our limbs
c.walking in a straight line with our eyes closed
What do we call a mental predisposition that influences our interpretation of a stimulus?
Perceptual Set
We know that the color of a printed page has not changed as it moves from sunlight into shadow. Why is this?
