• Place in order the steps involved for sound waves to create a perception of the sound
in the brain. -✓✓ 1) Sound Waves enter the auditory canal.
2) The eardrums vibrate
3) The hammer, anvil, and stirrup transfer vibration to the oval window
4) Pressure waves in the cochlea stimulate hair cells
5)Information is carried by the auditor nerve to the thalamus
• Match each Gestalt perceptual grouping rule with its corresponding example. -✓✓ -
illusory contours : Shapes are perceived even if they are not outlined.
- continuity :A person sees an object as a whole even when part of it is hidden behind
another object.
- closure : A person completes incomplete figures that have gaps.
- proximity : A person groups together objects that are near one another.
- similarity : A person groups together objects that look the same.
• Which of the following facts support the trichromatic theory of color vision and which
support the opponent-process theory? -✓✓ Trichromatic Theory
-We can create yellow light by combining red light and green light in equal amounts.
-The eye contains three types of cone cells, activated by short, medium, and long
wavelengths.
Opponent-Process Theory
-After staring at a yellow spot, a person sees a blue afterimage, and after staring at a
red spot, the person sees a green afterimage.
-We have more trouble visualizing reddish green than reddish yellow.
• Place in order the steps involved for flavors on the tongue to create a perception in the
brain. -✓✓ 1) Chemical substances in food dissolve in saliva
2) Taste receptors are stimulated
3) Signals are sent to the thalamus
4) The frontal lobe perceives taste
• Light stimuli entering the eye encounter a series of structures while traveling to the
brain. Place the structures in the correct order -✓✓ 1. Cornea
2. Retina
3. Rods and Cones
4. Ganglion Cells
5. Optic Nerve
6. Thalamus
7. Primary Visual Cortex
, • Match the senses and receptors with the types of sensory input they address. -✓✓ 1.)
Kinesthetic Sense: movement
2.) Pressure Receptors: touch
3.) Vestibular Sense: balance
4.) Warm and Cold Receptors: temperature
• Abram was violently tackled in a football game. Though he did not notice the injury
during the game, afterward he feels a dull pain in his leg. -✓✓ Dull pain that occurs after
an initial injury is sent to the brain using slow fibers that do not have a myelin
sheath.When we are not distracted, sharp initial pain travels quickly to the brain on
myelinated axons, and dull pain travels more slowly on nonmyelinated axons.
• Of all the senses, olfaction has the most direct route to the brain. Which of the
following statements accurately characterize our perception of odor? -✓✓ Correct
Answer(s)
-The smell might evoke an emotion or a memory if it is familiar.
-We know immediately whether the smell is pleasant or unpleasant.
-Women are generally better at identifying odors than men.
Incorrect
-We can usually identify odors by name.
-Every odor that we can detect is processed by a single olfactory receptor that is
specific to that scent.
• Match each example with the sensory system it activates. -✓✓ kinesthetic sense:
playing basketball
slow pain fibers: Having sore gums after dental work
vestibular sense: seasickness
fast pain fibers: Hitting your thumb with a hammer
• kinesthetic sense -✓✓ allows us to coordinate our movements.. ex. playing basketball
• slow pain fibers -✓✓ Slow pain fibers keep us from further injury by reminding us not to
use the injured body part so we can recover. ex Having sore gums after dental work
• vestibular sense -✓✓ responsible for our sense of balance. ex. seasickness
• fast pain fiber -✓✓ protect us by causing us to immediately withdraw from a painful
stimulus. ex. Hitting your thumb with a hammer
• What are true statements about the perception of touch in the somatosensory cortex. -
✓✓ A lot of space in the cortex is devoted to processing touch information from the lips.
A touch on the hand and a touch on the arm are processed in nearby areas of the
somatosensory cortex.
