A witness describes a suspect's vehicle as 'dark-colored, four-door, with a dent on the rear bumper.' Which detail is most likely to be inaccurate when recalled later?
Answer: The general color
General color descriptors like 'dark' are often misremembered because witnesses encode approximate hue rather than specific shade, making it susceptible to distortion over time.
An officer observes a scene for 30 seconds, then is asked to recall it. Which memory technique best improves later accuracy?
Answer: Closing eyes and mentally scanning the scene zone by zone
Mentally scanning a scene in systematic zones (left-to-right, near-to-far) encodes spatial layout more completely than selective or verbal rehearsal alone.
You observe a suspect wearing: blue jeans, white sneakers, a red hoodie, and a black baseball cap. Thirty minutes later you recall 'blue jeans, white shoes, a dark hoodie.' What memory error occurred?
Answer: Color generalization
Color generalization occurs when a specific vivid color (red) is remembered only as a broad category (dark), a common perceptual memory compression.
An officer needs to remember the license plate 'XRT-4829.' Which strategy is MOST effective?
Answer: Chunking as 'XRT' plus '48-29' and creating a brief verbal cue
Chunking breaks the plate into manageable units and a verbal cue (mnemonic) links the chunks, improving both encoding and retrieval.
A study room contains: a desk, two chairs, a bookshelf with five books, a lamp, and a closed window. How many distinct objects are present?
Answer: 10
Counting: desk (1), chairs (2), bookshelf (1), five books (5), lamp (1) = 10 distinct objects total.
Which factor is most likely to reduce an officer's observation accuracy at a crime scene?
Answer: Experiencing elevated stress during the incident
High stress narrows attention (tunnel vision), reduces peripheral detail encoding, and impairs working memory consolidation during the event.
An officer who observed a robbery is asked to describe the suspect's height. The officer says '5'10"' but the suspect is 6'1". This error is BEST explained by:
Answer: Distance and angle distorting perceived height
Height perception is strongly affected by viewing distance, angle, and reference objects present in the scene, often causing systematic underestimation.
