D. Short Answer (30 Points). Complete 6 of the 8 questions below.
1. Describe the difference between Broca’s Aphasia and Wernicke’s Aphasia. Focus on the way both are
caused, and what is affected.
Broca’s Aphasia  abnormality in the frontal lobe  inability to create and form speech
Wernicke’s Aphasia  abnormality in the temporal lobe  inability to comprehend speech/make
sensible sentences
2. Describe the case of Phineas Gage. Include information on both his injury, and the after-effects.
Gage had a metal rod go through the frontal lobe of his skull. The damage occurred to his frontal
lobe and impacted his personality (before the accident he was reasonable and well-tempered,
after he was impulsive and aggressive). Showed scientists that certain brain parts govern certain
functions.
3. Define the difference between sensation and perception.
Sensation is how the body receives information from the environment (outside world) and
perception is the way that we make sense of this information.
4. What is the purpose of brain lateralization? How do the functions of the side brains differ?
Purpose: to localize any form of injury or abnormality; Function  Left side: see detail, analyze
whereas Right side: whole picture, creative
5. The human frontal lobe is much more developed than other mammals. Why might this be?
Humans have developed the ability to reason, control emotions, make decisions etc. All of these
functions occur in the frontal lobe
6. Why do parts of the primary gustatory cortex and the primary somatosensory cortex overlap?
Both taste and tactility (touch) play a part in our overall food experience. Our brains interpret
information on both taste and texture (touch) to create our entire eating experience.
7. What does the following quote mean ““If the human brain were so simple that we could understand it, we
would be so simple that we couldn’t”?
Our brain is so complex that we are not able to fully understand its power. If we could understand the
power of our brain, it would be much too simple.
8. What is conduction aphasia? Which two parts of the brain appear to be disconnected in this abnormality.
This is a lack of connection between Broca’s Area and Wernicke’s Area. This leads to an inability to
accurately repeat spoken language. The person can still make words correctly and understand language,
they just cannot directly repeat spoken words.

Cerebrum
Brainstem
Frontal Lobe
Occipital Lobe

F. Long Answer (20 Points). Answer 2 of the 3 Questions.
1. Describe the case of Charles Whitman briefly. Provide an argument that explains his behavior using
each of the following perspectives. Whitman was a well respected athlete and student. He was brought up
in a violent household, with an abusive father. Whitman was also known to use drugs and was shown to have
a brain tumor upon death. Whitman went on a shooting spree at his University.
a. Biological  Whitman’s tumour caused him to think and act irrationnaly
b. Sociocultural  Whitman’s suffering of abuse and his violent past impacted his behavior.
c. Humanistic  Despite these, Whitman had the capacity to choose his own actions. He was
simply evil.
2. What advantages are there to the way in which the brain is divided/specialized? What disadvantages?
Provide examples to support your ideas.
 Consider things as: injuries, protection, multi-tasking, split-brain in your answers
3. What are four techniques used to study the brain. Provide a positive and a negative for each method.
Pro
Con
1. Remove part of brain
take out part that is not working right
can cause harm
2. Examine brain damage note changes in behavior
someone has brain damage
3. Stimulate brain
can get desired response
requires surgery
4. Record brain activity
non-harmful
time/costs a lot
