Ɛhia

Which part of the retina translates color and fine detail?

Cones

Rods

Fovea

Optic Nerve

SSPBF4.a

Ɛhia

The way we perceive objects is determined by

seasonal winds

how others see it.

our expectations and attitudes about what we see

Ɛhia

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

SSPBF4.a

Ɛhia

Rods in the retina allow us to recognize

the depth, or distance, of objects

faces

colors

movement on the periphery

SSPBF4.a

Ɛhia

drag the term and line it up with the defintion

Draggable item		Corresponding Item
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

SSPBF4.c

Ɛhia

Which part of the eye controls light entry?

Pupil

Retina

Iris

Lens

SSPBF4.a

Ɛhia

What term describes the minimum detectable stimulus intensity?

Sensory adaptation

Just noticeable difference

Absolute threshold

Perceptual set

SSPBF4.c

Ɛhia

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.

Ɛhia

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.

SSPBF4.f

Ɛhia

What part of the ear collects sound waves?

Inner ear

Outer ear

Cochlea

Middle ear

SSPBF4.a

Ɛhia

What is the function of the cochlea?

Convert sound waves to electrical signals

Balance the body

Protect the inner ear

Amplify sound waves

SSPBF4.a

Ɛhia

Place the following steps to the vision process in order.

visual cortex in the occipital lobe interprets signals
light passes through the pupil
photoreceptor cells (rods and cones) convert light into neural impulses and send them to ganglion cells
optic nerve carries signals to the brain
light passes through the cornea
light is focused by the lens onto the retina
axons send messages from the ganglion cells to the optic nerve

SSPBF4.a

Ɛhia

Group the following parts of the ear into the appropriate categories:

auditory canal
tympanic membrane (ear drum)
semi-circular canals
auditory nerve
pinnae
cochlea
ossicles

Outer Ear
Middle Ear
Inner Ear

SSPBF4.a

Ɛhia

Sort the following theories into the appropriate categories:

frequency theory
place theory
trichromatic theory
Volley theory
opponent process theory

Vision Theory
Hearing Theory

SSPBF4.c

Ɛhia

Place the following steps of hearing into the correct order.

hair cells transmit neural impulses to auditory nerve
the pinnae collects sound waves
sound waves travel down the auditory canal
sound waves vibrate the ear drum
vibrations are passed through the fluid in the cochlea
vibrations cause the ossicles to vibrate
ossicles (stapes) press against the cochlea
impulses end up in the auditory cortext of the temporal lobe
hair cells (auditory receptor cells) are stimulated

SSPBF1.a

Ɛhia

Sort the concepts below into the correct categories.

retinal disparity
clarity
convergence
texture gradient
relative size
relative height

monocular clues
binocular clues

SSPBF4.c

Ɛhia

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

SSPBF4.c

Ɛhia

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

SSPBF4.c

Ɛhia

Which concepts explains why we perceive the door in this picture is moving?

Stroboscopic motion

Law of Continuity

Phi Phenomenon

Perceptual constancy (of shape)

SSPBF4.c

Ɛhia

Sort the descriptions and examples into the appropriate category of drug.

cause perception without actual sensation
example: LSD (acid)
example: caffeine
example: alcohol
increase brain activity and autonomic functions such as breathing and heart rate
decrease brain activity and autonomic functions such as breathing and heart rate

Depressants
Stimulants
Hallucinogens

SSPBF2.f

Ɛhia

Which is an example of an altered state of consciousness?

Routine daily activities.

Dreaming during sleep phases.

Normal wakefulness.

Deep thinking during meditation.

SSPBF2.a

Ɛhia

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.

SSPBF2.b

Ɛhia

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.

SSPBF2.b

Ɛhia

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.

SSPBF2.b

Ɛhia

sleep
unconsciousness
biofeedback
meditation
preconsciousness
wakefulness

Increased awareness of self and environment
Decreased awareness of self and environment

SSPBF2.a

Ɛhia

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

SSPBF2.b

Ɛhia

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

SSPBF2.c

Ɛhia

What does Freud's theory suggest dreams represent?

Random brain activity

Daily concerns and tasks

Future predictions

Unconscious desires and wishes

Ɛhia

Drugs can...

increase or decrease neurotransmitters in the brain

block neurotransmitter reuptake

mimic neurotransmitters to achieve the same result

all of these
