Police Officer Selection Test (POST) Memory and Observation Syllabus

What is rehearsal, and how does it aid memorizing a written briefing?

Rehearsal is the repeated, active review of information (mental or aloud) that moves it from short-term into long-term memory and strengthens retention.

What is the difference between maintenance rehearsal and elaborative rehearsal?

Maintenance rehearsal is simple repetition to hold information briefly; elaborative rehearsal links new information to existing knowledge for deeper, longer-lasting storage.

In a Memory and Observation test, what is the recommended strategy for studying a briefing image or text before questions appear?

Actively look for and mentally note who, what, where, when, names, numbers, addresses, descriptions, and any unusual details, then rehearse them.

What is a mnemonic, in the context of memory techniques?

A learning aid (acronym, rhyme, image, or pattern) that organizes information into a more memorable form to improve recall.

What is the 'peg system' mnemonic technique?

A method that pre-memorizes a fixed list of 'pegs' (often number-rhyme pairs like one-bun, two-shoe) onto which new items are mentally hooked for ordered recall.

When describing a person's height without measurement, what reference technique is used?

Comparing the person's height to a known fixed object nearby (e.g., a door frame ~6'8", standard car roof, or the witness's own height).

What four broad categories typically organize a complete physical description of a person?

General (sex, race, age, height, weight, build), head (hair, eyes, face), clothing, and distinguishing features/marks.

Why is clothing considered a less reliable identifier than physical features in eyewitness recall?

Because clothing can be easily and quickly changed, removed, or layered, whereas physical features are permanent.

What is the difference between a vehicle's 'make' and 'model'?

The make is the manufacturer or brand (e.g., Ford, Toyota), while the model is the specific product line within that brand (e.g., F-150, Camry).

List common vehicle body styles an observer should be able to distinguish.

Sedan, coupe, hatchback, SUV, pickup truck, van/minivan, convertible, station wagon, and crossover.

What does 'situational awareness' mean for an officer observing an environment?

Continuously perceiving and understanding the people, objects, exits, and changes in one's surroundings to anticipate threats and recall details accurately.

In Cooper's color code of situational awareness, what does Condition Yellow represent?

A state of relaxed but alert general awareness of one's surroundings with no specific threat identified.

In Cooper's color code, what does Condition Orange represent?

Heightened awareness focused on a specific potential threat that has been identified, with a readiness to respond.

What is a 'baseline' when observing an environment, and why does it matter?

The normal, expected pattern of behavior and conditions in a setting; knowing the baseline lets an observer quickly notice anomalies or discrepancies.

What is the misinformation effect in eyewitness memory?

A distortion of memory in which exposure to misleading information after an event alters a witness's recollection of the original event.

What does the acronym ADVOKATE refer to in assessing the reliability of an eyewitness observation?

Amount of time observed, Distance, Visibility, Obstructions, Known/seen before, Any reason to remember, Time elapsed since, and Errors/discrepancies in description.

When recalling a scene, what is the value of mentally 'taking a snapshot' (visualization)?

Forming a deliberate mental image freezes the scene's layout and detail, making it easier to retrieve specific positions and features later.

What is the difference between detecting an addition versus an omission when comparing two scenes?

An addition is an object/person present in the second image but not the first; an omission is something present in the first image that is missing in the second.

For license-plate recall, why is noting the state and plate color as important as the number?

Plate numbers can be partial or misread, so the issuing state and background/color help narrow identification and confirm the plate against records.

What is 'flashbulb memory'?

A vivid, detailed, and long-lasting memory of the circumstances surrounding a shocking or highly emotional event, though not always fully accurate.

What is the recommended way to recall a sequence of events from a briefing in correct order?

Encode events chronologically using a timeline or story (narrative chaining), linking each event to the next so order is preserved on retrieval.

What is the difference between a witness's 'estimate' and 'measurement' descriptors, and which should be flagged?

An estimate is an approximation (about 6 feet, around 30 years old); a measurement is exact. In testing, descriptors are usually estimates and should be given as ranges.

What encoding strategy improves recall of a person's name during observation?

Association — linking the name to a distinctive feature, rhyme, or familiar person, and repeating it to reinforce the link.

Why does dual coding (combining verbal and visual information) improve memory of a briefing?

Storing information as both words and mental images creates two retrieval routes, increasing the chance of successful recall.

When observing objects at a crime scene, what spatial details should be memorized?

The object's identity, location/position relative to landmarks, quantity, condition, and relationship to other objects or persons.

What is interference in memory, and what are its two types?

Interference is when memories disrupt one another: proactive interference (old memories hinder new) and retroactive interference (new memories hinder recall of old).

Why is recall accuracy higher immediately after observation than after a delay?

Because memory traces decay over time and are increasingly subject to interference and distortion, so the forgetting curve drops sharply at first.

According to the Ebbinghaus forgetting curve, what happens to retention without review?

Memory of newly learned information declines rapidly at first and then levels off; spaced review (rehearsal) flattens the curve and improves retention.

What is the benefit of spaced repetition over cramming for memorizing briefing material?

Spaced repetition reviews information at increasing intervals, strengthening long-term retention far more effectively than a single massed study session.

When estimating a suspect's age, what visual cues guide the observer?

Skin condition (wrinkles, smoothness), hair color and hairline, posture, clothing style, and overall facial maturity — reported as an age range.

What distinguishes a reliable physical description from an unreliable one in eyewitness reporting?

A reliable description is specific, given soon after the event, based on good viewing conditions, and consistent across retellings; unreliable ones are vague, delayed, or shifting.
