How Memory Gets Things Wrong

Memory feels like playback. Almost a century of laboratory work says it is closer to reconstruction, and the seams show up in predictable places.

About this topic

The everyday model of memory is a recording: something happened, it went in, and remembering plays it back with more or less fidelity. Laboratory work has been chipping away at that picture since the 1880s, when Hermann Ebbinghaus measured his own forgetting with lists of nonsense syllables, and it took another blow in the 1930s when Frederic Bartlett found that people retelling an unfamiliar story steadily reshaped it toward their own expectations. What replaced the recording model is messier and more useful. Remembering is treated as a rebuild from fragments, general knowledge and whatever has been encountered since — which explains why confident memories can be wrong in specific, repeatable ways. The questions here cover the best-established of those effects, the ones that show up across many laboratories rather than in a single striking study.

  1. 1The misinformation effect describes what?

    • A A tendency to recall the first item in a list best
    • B Memory for an event being altered by information encountered afterwards Correct
    • C A refusal to believe an accurate account
    • D Forgetting caused by a blow to the head

    Answer: B. Memory for an event being altered by information encountered afterwards

    Why: Elizabeth Loftus demonstrated it by changing a single verb in a question about a filmed collision. The finding has held up across a great many independent replications.

  2. 2Ebbinghaus's forgetting curve describes what pattern?

    • A Rapid loss of new material at first, then a much slower decline Correct
    • B Steady loss at a constant rate
    • C No loss at all until sleep
    • D Loss that accelerates over weeks

    Answer: A. Rapid loss of new material at first, then a much slower decline

    Why: He ran the experiments on himself using nonsense syllables so that existing meaning could not help him. The shape he found still turns up in studies of real classroom material.

  3. 3The serial position effect means people recall which parts of a list best?

    • A Only the middle
    • B Only the last two items
    • C The longest words
    • D The beginning and the end Correct

    Answer: D. The beginning and the end

    Why: The two halves have different causes: early items get more rehearsal, while late ones are still active when recall starts. A short delay wipes out the end-of-list advantage but leaves the start intact.

  4. 4Flashbulb memories are best described as what?

    • A Images that appear just before sleep
    • B Memories recovered under hypnosis
    • C Vivid, confidently held memories of learning shocking news Correct
    • D Photographic recall of a printed page

    Answer: C. Vivid, confidently held memories of learning shocking news

    Why: Researchers who collected accounts the day after an event and again years later found the details drifted like ordinary memory. What stayed unusually high was the rememberer's confidence.

  5. 5In memory research, chunking means what?

    • A Splitting study into timed intervals
    • B Grouping items into larger meaningful units so more can be held at once Correct
    • C Repeating an item aloud until it sticks
    • D Discarding old memories to make room

    Answer: B. Grouping items into larger meaningful units so more can be held at once

    Why: George Miller's well-known figure of seven items came out of this work. Later estimates put raw capacity closer to four chunks once rehearsal is prevented.

  6. 6Working memory differs from a simple short-term store because it does what?

    • A Holds information while actively manipulating it Correct
    • B Stores material permanently
    • C Operates only during sleep
    • D Handles nothing but words

    Answer: A. Holds information while actively manipulating it

    Why: Alan Baddeley and Graham Hitch proposed separate subsystems for sound and for visual material. That split is why someone can rehearse a phone number and picture a route at the same time.

  7. 7Retrograde amnesia is the loss of which memories?

    • A Those formed after it
    • B Only motor skills such as cycling
    • C Only the memory of faces
    • D Those formed before the injury or illness Correct

    Answer: D. Those formed before the injury or illness

    Why: Anterograde amnesia is the mirror case, covering everything after the event. The two often appear together because overlapping brain structures serve different stages of memory.

  8. 8The tip-of-the-tongue state shows that people can often retrieve what?

    • A Nothing whatever about the target word
    • B Only words from a second language
    • C Partial information such as the first letter or the number of syllables Correct
    • D The complete word after exactly ten seconds

    Answer: C. Partial information such as the first letter or the number of syllables

    Why: It happens more with proper names than with ordinary nouns. Names carry little meaning of their own, so there are fewer routes into them.

  9. 9Source monitoring means keeping track of what?

    • A Which language a memory was formed in
    • B Where a remembered piece of information originally came from Correct
    • C How many times a fact has been repeated
    • D The exact date of every memory

    Answer: B. Where a remembered piece of information originally came from

    Why: Failures explain how a rumour heard in passing can later feel like something read in a newspaper. The content survives while its origin quietly detaches.

  10. 10Why do psychologists call remembering reconstructive?

    • A Each recall rebuilds the event from fragments and general knowledge Correct
    • B Because memories sit in single dedicated brain cells
    • C Because nothing is ever truly forgotten
    • D Because memory only works during sleep

    Answer: A. Each recall rebuilds the event from fragments and general knowledge

    Why: Frederic Bartlett showed it in the 1930s by having British students retell an unfamiliar folk tale. Each retelling shifted the story further toward their own cultural expectations.
