Which part of the retina translates color and fine detail?
Cones
Rods
Fovea
Optic Nerve
The way we perceive objects is determined by
seasonal winds

how others see it.
our expectations and attitudes about what we see
The lens of the eye is responsible for
allowing enough light to enter the eye
converting light into electrical impulses
processing an image
keeping objects in focus
Rods in the retina allow us to recognize
the depth, or distance, of objects
faces
colors
movement on the periphery
drag the term and line it up with the defintion
closure
idea that people prefer to see smooth patterns rather than disrupted oned
law of continuity
nearness of objects or figures to each other
law of similarity
tendency to perceive a complete figure even if gaps exist
proximity
idea that people like to group similar items together
Which part of the eye controls light entry?
Pupil
Retina
Iris
Lens
What term describes the minimum detectable stimulus intensity?
Sensory adaptation
Just noticeable difference
Absolute threshold
Perceptual set
What is the difference between sensation and perception?
Perception occurs before sensation.
Sensation involves interpretation; perception is detection.
Sensation is detection; perception is interpretation of stimuli.
Sensation only relates to sight.
How does bottom-up processing influence perception?
It ignores sensory input completely.
It always involves visual stimuli only.
It is faster than top-down processing.
It relies solely on prior knowledge.
It starts with sensation and builds to understanding.
What part of the ear collects sound waves?
Inner ear
Outer ear
Cochlea
Middle ear
What is the function of the cochlea?
Convert sound waves to electrical signals
Balance the body
Protect the inner ear
Amplify sound waves
Place the following steps to the vision process in order.
axons send messages from the ganglion cells to the optic nerve
visual cortex in the occipital lobe interprets signals
optic nerve carries signals to the brain
photoreceptor cells (rods and cones) convert light into neural impulses and send them to ganglion cells
light passes through the cornea
light passes through the pupil
light is focused by the lens onto the retina
Group the following parts of the ear into the appropriate categories:
auditory canal
tympanic membrane (ear drum)
semi-circular canals
cochlea
ossicles
auditory nerve
pinnae
Outer Ear
Middle Ear
Inner Ear
Sort the following theories into the appropriate categories:
place theory
frequency theory
trichromatic theory
Volley theory
opponent process theory
Vision Theory
Hearing Theory
Place the following steps of hearing into the correct order.
impulses end up in the auditory cortext of the temporal lobe
ossicles (stapes) press against the cochlea
vibrations cause the ossicles to vibrate
hair cells transmit neural impulses to auditory nerve
hair cells (auditory receptor cells) are stimulated
sound waves vibrate the ear drum
the pinnae collects sound waves
sound waves travel down the auditory canal
vibrations are passed through the fluid in the cochlea
Sort the concepts below into the correct categories.
retinal disparity
texture gradient
relative size
convergence
clarity
relative height
monocular clues
binocular clues
According to Weber's Law, which of the following is true?
when a stimulus intensity is high, the JND will be high
when a stimulus is low, the JND will be high
when a stimulus intensity is high, the Just-Noticeable Distance (JND) will be low
when the JND is high, the stimulus intensity will be low
There is a fan that is constantly running in Melinda's room. Most days, however, she forgets that it's on, even though it is noisy. Which idea explains why Melinda doesn't hear her fan?
law of continuity
sensory adaptation
threshold theory
just noticeable difference
Which concepts explains why we perceive the door in this picture is moving?
Stroboscopic motion
Law of Continuity
Phi Phenomenon
Perceptual constancy (of shape)
Sort the descriptions and examples into the appropriate category of drug.
example: caffeine
example: LSD (acid)
increase brain activity and autonomic functions such as breathing and heart rate
cause perception without actual sensation
decrease brain activity and autonomic functions such as breathing and heart rate
example: alcohol
Depressants
Stimulants
Hallucinogens
Which is an example of an altered state of consciousness?
Routine daily activities.
Dreaming during sleep phases.
Normal wakefulness.
Deep thinking during meditation.
What stage of sleep is associated with dreaming?
Stage 2 is also for dreaming.
Stage 1 is the dreaming stage.
NREM sleep includes all dreaming.
REM sleep occurs during dreaming stages.
Circadian rhythms primarily regulate which biological function?
Daily exercise routines are regulated.
Food intake is affected by rhythms.
Heart rates are determined by circadian rhythms.
Sleep-wake cycles are managed by circadian rhythms.
Which sleep stage is the deepest and most restorative?
Stage 1 is the deepest stage.
REM sleep is the most restorative.
Stage 3 sleep is the deepest restorative stage.
Stage 2 is the deepest stage.
preconsciousness
sleep
unconsciousness
biofeedback
wakefulness
meditation
Increased awareness of self and environment
Decreased awareness of self and environment
Which best explains how circadian rhythms are impacted by environment?
exposure to cold weather causes the brain to START producing melatonin, which helps people fall asleep
exposure to fresh air causes the brain to STOP producing melatonin, which helps people stay awake
exposure to sunlight causes the brain to STOP producing melatonin (a sleep hormone), which helps people stay awake during the day
exposure to sunlight causes the brain to START producing melatonin, which helps people stay awake
Which of these is NOT a theory of why people sleep?
growth theory: the brain releases growth hormones while asleep
repair and restoration theory: the brain and body heal during sleep
evolutionary theory: people sleep to conserve energy and hide while predators are awake
learning theory: the brain absorbs new knowledge from the environment during sleep
What does Freud's theory suggest dreams represent?
Random brain activity
Daily concerns and tasks
Future predictions
Unconscious desires and wishes
Drugs can...
increase or decrease neurotransmitters in the brain
block neurotransmitter reuptake
mimic neurotransmitters to achieve the same result
