Which type of receptor sees color?
Cones
100
Which type of receptor is sensitive to light?
Rods
100
What is the focusing of attention on selected aspects of the environment, and the blocking of others?


Hint: this protects us from being overwhelmed with sensations

Selective attention
100
What are the three small bones that vibrate in the inner ear?
hammer, anvil, and stirrup
100
What gives information about the position and motion of the body as a whole using three semicircular canals in the inner ear that respond to the rotation of the head?
Equilibrium
200
What are the three characteristics of light waves?
Hue, brightness, and saturation
200
What are the five visual constancies?
Shape, location, size, brightness, and color
200
What is the failure to consciously perceive something you are looking at because you are not attending to it?
Inattentional blindness
200
True or False: Sensory deprivation can lead to hallucinations
True
200
What tells us about the location and movement of body parts using pain and pressure receptors in muscles, joints, and tendons?
Kinesthesis
300
What are Gestalt principles?



Strategies for building perceptual units



300
What is something someone who has lost an eye will have trouble with?
Depth Perception because it requires binocular vision
300
A decline in sensory responsiveness occurs when a stimulus is unchanging. This is known as:
Sensory Adaptation



300
What is the smallest amount of energy a person can detect reliably (~50% of the time)?
Absolute threshold
300
What are the four skin senses?
Touch (or pressure), warmth, cold, and pain
400
Which theory explains why we see afterimages?
Opponent-process theory
400
Which theory attributes color deficiencies in vision to a lack of cones?
Trichromatic Theory
400
What is the smallest difference in stimulation that a person can detect reliably?
Difference threshold/just noticeable difference
400
What are the three characteristics of sound waves?
Loudness, pitch, and timbre
400
What are the five basic tastes?
Sour, salty, bitter, sweet, and umami
500
What is the order in which we process visual information?
Rods and cones connect to bipolar neurons that connect to ganglion cells, whose axons converge to form the optic nerve. The optic nerve carries information from the eye to the brain.
500
Why is the visual system not like a camera?

Eyes are not a passive recorder of the external world. Neurons actually build a picture of the external world by detecting the meaningful features


500
Signals received by the sense organs stimulate different nerve pathways, which terminate in different areas of the brain. This is known as the:
Doctrine of specific nerve energies
500
What kind of auditory cue is loudness?


Hint: what does it tell us?

Distance cue

Describe the Gate Control Theory of chronic pain
In order to experience pain, impulses must pass through a "gate" to the CNS. The gate is made of neurons that either transmit or block the pain message. Chronic pain results when the fibers that close the gate are damaged.
