Understanding Psychology (10th Ed)

2.
Electrodes placed around the 
skull record the electrical signals 
transmitted through the brain.
3.
This technique provides a three-
dimensional view of the brain 
by aiming a magnetic fi eld at the 
body. 

2.
Match the portion of the brain with its function:
a.
medulla
1.
Maintains breathing and 
b.
pons
heartbeat.
c.
cerebellum
2.
Controls bodily balance.
d.
reticular
3.
Coordinates and integrates
formation 
muscle 
movements.
4.
Activates other parts of the
brain to produce general
bodily arousal.
3.
A surgeon places an electrode on a portion of your brain 
and stimulates it. Immediately, your right wrist involun-
tarily twitches. The doctor has most likely stimulated a 
portion of the 
area of your brain.
4.
Each hemisphere controls the 
side of the body.
5.
Nonverbal realms, such as emotions and music, are con-
trolled primarily by the 
hemisphere of the 
brain, whereas the 
hemisphere is more 
responsible for speaking and reading.

Before sophisticated brain-scanning techniques were de-
veloped, behavioral neuroscientists’ understanding of the 
brain was based largely on the brains of people who had 
died. What limitations would this pose, and in what areas 
would you expect the most signifi cant advances once 
brain-scanning techniques became possible?
2.
Could personal differences in people’s specialization of 
right and left hemispheres be related to occupational suc-
cess? For example, might an architect who relies on spatial 
skills have a pattern of hemispheric specialization differ-
ent from that of a writer?
3.
From the perspective of an educator: How might you use dif-
ferent techniques to teach reading to boys and girls based 
on the brain evidence?
