What you’ll learn

  1. Memory Is ReconstructionExplain why recall reconstructs an event from selected details, gist, and later knowledge.Memory is useful because it compresses experience, but gist and vividness do not guarantee exact detail.
  2. Source MattersUse source monitoring and independent evidence to distinguish confidence from accuracy.A remembered detail can be real information from the wrong source, so confidence should be checked against where and how it was encountered.
  3. Suggestion and ImaginationExplain how question wording and imagination can increase false familiarity.Leading questions and vivid imagination can make a detail accessible without proving that it was perceived in the original event.
  4. Recall Can Update MemoryDescribe post-event misinformation and reconsolidation cautiously, separating observations from mechanisms.Recall can strengthen or reshape memory, but a changed report does not reveal by itself whether an old trace was erased, hidden, or joined by new information.
  5. Calibrating ConfidenceApply records, precise language, and calibrated confidence when a memory matters.Useful memories need not be literal transcripts; high-stakes claims deserve independent support and room for revision.

Questions this course answers

Why can a vivid memory still contain an error?

Memory is reconstructive, so vividness can reflect accessibility without proving that every detail matches the original event.

Put a careful memory check in order.

Separating confidence, source, evidence, and the final claim prevents a feeling from silently becoming certainty.

Match each experience to the most careful interpretation.

Suggestion and imagination can change how accessible a detail feels without establishing that the detail was present in the original event.

Why should changed recall not automatically be described as erasure of the original memory?

The misinformation effect is real as a change in reported memory, but several mechanisms can produce that change. Good explanations distinguish the observation from the proposed process.

Complete the sentence: confidence and ___ are not identical measurements.

Confidence is a subjective feeling, while accuracy concerns correspondence with evidence; they can come apart.
