Sensation

The process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment. 

100

Top-down processing?

information processing where we construct perceptions drawing on our experiences and expectations

100

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?

just-noticeable difference

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

200

Transduction

Conversion of stimulus energies into neural impulses 

200

Place theory? 

pitch is linked to the place where the cochleas membrane is stimulated

200

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 

200

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

200

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

300

Perceptual Set

A mental predisposition to perceive one thing and not another 

300

Frequency theory?

we sense pitch because of the rate of nerve impulses travelling up the auditory nerve matches the frequency of a tone 

300

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

300

What is the purpose of the Iris?

To allow light into the eye

300

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

400

Binocular Cues

Depth cues, such as retinal disparity, that depend on the use of two eyes

400

Opponent-processing theory

opposite retinal processes enable color vision.

400

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

400

Which perception process are the hammer,anvil and stirrup involved with?

Transmitting sound waves to the cochlea

400

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

500

Kinesthesia 

The system fore sensing the position and movement of individual body parts 

500

Trichromatic Theory

retina contains three color receptors - red, blue and green. Which allows us to see color

500

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

500

What do we call a mental predisposition that influences our interpretation of a stimulus?

Perceptual Set

500

We know that the color of a printed page has not changed as it moves from sunlight into shadow. Why is this?

Color constancy/perceptual constancy
