20 of 50 cards from the Memory deck — real questions with worked answers.

1. In the RAF Airman/Airwoman Selection Test (AST), what is the purpose of the 'Memory' subtest?

   It assesses short-term and working memory by testing your ability to memorise and reproduce sequences of illuminated patterns and to hold/manipulate information (such as letters) while ignoring distractions.

2. What two distinct memory tasks make up the AST Memory test?

   1) A visual task: memorising and reproducing a sequence of illuminated squares/patterns on a grid. 2) A verbal/working-memory task: holding letters in mind, ignoring distractor letters, and recalling the correct ones (often the letters either side of a distractor).

3. Define 'short-term memory' (STM).

   The temporary store that holds a small amount of information for a brief period (seconds) in conscious awareness, before it is either forgotten or transferred to long-term memory.

4. Define 'working memory'.

   A limited-capacity system that temporarily holds AND actively manipulates information while performing cognitive tasks, such as updating, reordering, or ignoring distractors.

5. What is the difference between short-term memory and working memory?

   Short-term memory simply stores information passively for a short time, whereas working memory both stores and manipulates that information (e.g., updating it or filtering distractors) to carry out a task.

6. According to Miller's classic finding, what is the typical capacity of short-term memory?

   About $7 \pm 2$ items (between 5 and 9 chunks) — the 'magic number seven'.

7. What is 'chunking' in memory?

   Grouping individual pieces of information into larger meaningful units (chunks) so that more total information can be held within the limited 5-9 item capacity of short-term memory.

8. Give an example of how chunking helps recall a long number string.

   A string like 1947194520011966 is hard to recall as 16 digits, but chunking into 1947 1945 2001 1966 (four 4-digit groups) reduces it to 4 memorable chunks.

9. In the AST illuminated-pattern task, what skill is being measured when squares light up briefly and you must repeat the sequence?

   Visual-spatial short-term memory and serial recall — encoding the position and ORDER of illuminated cells and reproducing them accurately.

10. Why does the ORDER of the illuminated squares matter in the pattern-sequence task?

    Because it is a test of serial (sequential) recall — reproducing the same squares in the wrong order is counted as an error, so both location and sequence must be retained.

11. What is 'short exposure pattern retention'?

    The ability to take in (encode) a visual pattern that is shown for only a very brief moment and hold an accurate image of it long enough to reproduce or recognise it.

12. Why is rapid encoding important during short-exposure pattern tasks?

    Because the stimulus disappears almost immediately, you must encode the whole pattern in one quick 'snapshot'; slow, piece-by-piece encoding means parts of the pattern fade before they are stored.

13. What memory phenomenon causes a briefly-shown visual pattern to remain available for a fraction of a second after it disappears?

    Iconic memory (visual sensory memory) — a very brief, high-capacity visual trace lasting roughly $0.25\text{–}0.5$ seconds that can be 'read off' immediately after exposure.

14. What is the approximate duration of iconic (visual sensory) memory?

    Around a quarter to half a second (about $250\text{–}500\ \text{ms}$).

15. What is the approximate duration of unrehearsed short-term memory?

    Roughly 15-30 seconds before the information decays, unless it is actively rehearsed.

16. What does 'reproducing a pattern after a delay' test that immediate reproduction does not?

    Resistance to decay and interference — it checks whether you can maintain an accurate memory trace over a gap (often filled with another task) rather than just echoing it instantly.

17. What is 'decay' as a cause of forgetting?

    The fading of a memory trace simply due to the passage of time when the information is not rehearsed.

18. What is 'interference' as a cause of forgetting?

    When other information disrupts a memory: new incoming items push out or confuse the stored ones, making accurate recall harder.

19. Distinguish proactive interference from retroactive interference.

    Proactive interference: OLD information disrupts recall of NEW information. Retroactive interference: NEW information disrupts recall of OLD (already-learned) information.

20. In the AST letters task, distractor letters are presented. What is the typical rule for which letters to remember?

    You ignore the distractor(s) and remember/report the relevant target letters — commonly the letters immediately to the LEFT and RIGHT of the distractor letter.
