Definition
Reconstructive memory is the principle, established by Frederic Bartlett in the 1930s and elaborated by Elizabeth Loftus from the 1970s onward, that memory is not a recording but a reconstruction. At retrieval, the brain assembles a coherent account from stored fragments, current knowledge, schemas, and external cues — filling gaps with plausible inferences and incorporating post-event information without the rememberer noticing.
The implication for forensic settings is profound. An eyewitness recalling a crime is not playing back what they saw; they are reconstructing it under the influence of intervening news coverage, prior questioning, conversations with other witnesses, and the way a police interviewer phrases questions. The reconstructed memory feels just as vivid and certain as a more accurate one.
Why it matters
Where it shows up
Reconstructive memory underpins court instructions about leading questions, restrictions on police questioning techniques, the design of the Cognitive Interview, and expert testimony cautioning juries about over-trusting confident witnesses. It also frames the modern debate over recovered-memory therapy.
