Ch01 - Forensic Science and Observation
1. Trained investigators know how to collect evidence based on its potential importance.
a. True
b. False
ANSWER: False
RATIONALE: The trained investigator collects all available evidence, without making judgments about its
potential importance. That comes later. Knowing which evidence is significant requires the
ability to recreate the series of events preceding the crime. The first step is careful and
accurate observation.

3. Using the scientific method requires the scientist or investigator to form a hypothesis that is based on prior knowledge
or observation.
a. True
b. False
ANSWER: True
RATIONALE: Scientists have established a rigorous study procedure known as the scientific method. After
stating the problem or question, the scientist proposes a hypothesis based on prior knowledge
or observation. A hypothesis is a possible explanation of a question or problem based on

4. A perception is what a person perceives using sight, taste, hearing, smell, and touch.
a. True
b. False
ANSWER: False
RATIONALE: An observation is what a person perceives using their senses. Every single moment, we are
gathering information about what is around us, through our senses—sight, taste, hearing,
smell, and touch. The sensory information that we observe is delivered to our brain.
Perception is our brain’s interpretation of our sensory observations after our brains have
filtered and processed the information.

5. The human brain can process information directly from perception to long-term memory.
a. True
b. False
ANSWER: False
RATIONALE: Information is processed in the brain in the following order: information enters the brain
through sensory inputs; we pay attention to only some of the information; this information is
then processed through our perception. Of the perceived information, only a portion passes
on to short-term memory, and even less of that information then becomes long-term memory.

6. A perception is only created after the brain has processed sensory information.
a. True
b. False

8. A witness is a person who has seen something related to a crime.
a. True
b. False

Ch01 - Forensic Science and Observation
ANSWER: True
RATIONALE: An eyewitness is a person who has seen someone, or something related to a crime and can
communicate their observations. Memory fades with time, and our brains tend to fill in
details that we feel are appropriate but may not be accurate.

9. After years of use, experts agree that showing a six-person photo collection to an eyewitness is beneficial for
identifying the perpetrator of a crime.
a. True
b. False
ANSWER: False
RATIONALE: An eyewitness is a person who has seen someone, or something related to a crime and can
communicate their observations. Memory fades with time, and our brains tend to fill in
details that we feel are appropriate but may not be accurate. The use of “six packs” of photos
(six-person photo collection) by law enforcement agencies is under review. Some experts feel
their use prejudices witnesses who want to be helpful and feel the suspect must be in the
photo array.

10. Often what a witness thought they saw and what really happened differ.
a. True
b. False
ANSWER: True
RATIONALE: When evaluating eyewitness testimony, the investigator must discriminate between fact, a
statement or information that can be verified, and opinion, a personal belief founded on
judgment rather than on direct experience or knowledge. Often what we think we saw and
what really happened differ. Someone fleeing the site of a shooting might look like a suspect
but could merely be an innocent bystander running away in fear of being shot.
