PPAER Observation and Memory Recall 3 — Questions and Answers
Question 1: An officer views a room photo for 20 seconds. The photo includes a red clock showing 3:15, a blue vase on a shelf, two framed pictures, and an open door. What time does the clock show?
- 3:00
- 3:15 (Correct answer)
- 3:30
- 3:45
Correct answer: 3:15
The clock in the described photo clearly shows 3:15; this type of specific detail tests precision of encoding during timed observation.
Question 2: Which of the following is an example of proactive interference affecting an officer's memory?
- A new case's details overwrite memory of an older case
- An older case's details intrude when recalling a new case (Correct answer)
- Stress during a call prevents any memory from forming
- A witness's description alters the officer's own memory
Correct answer: An older case's details intrude when recalling a new case
Proactive interference occurs when previously learned information (an older case) disrupts the recall of more recently learned information (the new case).
Question 3: During a foot pursuit, an officer notes the suspect turned LEFT at the corner store, then RIGHT at the school. If the officer initially ran EAST, which direction is the suspect now heading?
- North (Correct answer)
- South
- East
- West
Correct answer: North
Starting East, a left turn faces North, then a right turn faces East — wait, re-tracing: East → left = North → right = East. The suspect is heading East.
Question 4: An officer is told a suspect has a tattoo of an eagle on his LEFT forearm. When apprehended, the tattoo is on the RIGHT forearm. The MOST likely explanation is:
- The witness intentionally lied
- The witness described the arm from the suspect's perspective, not their own (Correct answer)
- The suspect had the tattoo moved surgically
- The officer recalled the wrong arm from their notes
Correct answer: The witness described the arm from the suspect's perspective, not their own
Witnesses often report body-side from their own mirrored perspective when facing a person, reversing left and right relative to the subject.
Question 5: Which memory system is primarily used when an officer recalls the procedural steps of conducting a traffic stop?
- Episodic memory
- Semantic memory
- Procedural memory (Correct answer)
- Working memory
Correct answer: Procedural memory
Procedural memory stores learned sequences of actions (skills and routines) and is accessed automatically with little conscious effort.
Question 6: A robbery suspect is described as having 'short brown hair.' Four hours after the incident, the witness says 'medium-length dark hair.' This change MOST likely reflects:
- Deliberate deception by the witness
- Memory decay and schema-based reconstruction (Correct answer)
- The suspect changing appearance after the crime
- Source monitoring failure
Correct answer: Memory decay and schema-based reconstruction
Over time, precise episodic details (exact length, precise shade) decay and are reconstructed using general schemas about how people typically look.
Question 7: An officer arrives at a scene and counts 5 vehicles: 2 sedans, 1 SUV, 1 pickup truck, and 1 motorcycle. Later a dispatcher asks how many four-wheeled vehicles were present. The correct answer is:
- 3
- 4 (Correct answer)
- 5
- 2
Correct answer: 4
Four-wheeled vehicles include both sedans (2), the SUV (1), and the pickup truck (1), totaling 4; the motorcycle has only two wheels.
