Memory and Observation for Dispatch Information
Memory and Observation for Dispatch Information tests your ability to retain and reproduce critical details-addresses, plate numbers, names, and physical descriptions-after a short delay or interruption. Items may present a fact, add a distraction, then ask you to select the exact detail.
Core rules
- Write immediately; do not hold a plate or apartment number in memory while listening to a new sentence.
- Chunk data: a plate such as 7BX-4291 becomes 7BX / 42 / 91; an address such as 4217 103rd Street becomes 42-17 / 103 / Street.
- Rehearse silently in the same order every time, then verify by reading back.
- Use a phonetic alphabet for letters that sound alike: B as Bravo, D as Delta, P as Papa.
- Record descriptions in a fixed order: sex, race, age, height, build, clothing, direction.
Worked example
Caller: 'He drove off in a blue sedan, plate 7BX-4291, east on 103rd.' After a distraction, reproduce the plate as 7BX-4291, not 7BX-4921. Chunk it as 7BX / 42 / 91, say it back once, and write it before asking the next question. The reasoning: transposition of 29 and 91 is a common encoding error; chunking plus read-back catches it while the caller is still available.
Traps
- Guessing a missing digit instead of asking for repetition.
- Writing after a second task instead of immediately.
- Confusing similar sounds: 15/50, B/D, M/N.
- Adding a description detail the caller did not give.
- Trusting a single hearing of a plate without read-back.
