Memory Is Rebuilt

Written by Studio AM.

Memory is often compared with a recording that can be replayed unchanged. Research shows that later information can influence what people report remembering. Recall uses stored information, but it can also be shaped by the wording of a question asked afterward.

In experiments by Elizabeth Loftus and John Palmer, participants watched films of car accidents. One experiment found higher speed estimates when a question used smashed rather than hit. In a second experiment, participants who received smashed were more likely a week later to report broken glass that the film did not contain.

These results show that a small change in wording can affect both an immediate estimate and a later report. They support concern about information introduced after an event. Researchers must still distinguish changes in memory from changes in how people choose to answer a question.

An interviewer can reduce this risk by asking open questions before introducing suggested details. Asking what someone remembers differs from asking how much glass they saw. The latter is leading: it points toward an answer by assuming glass was present. Someone recalling an event may sincerely accept that suggestion, so confidence alone cannot settle whether the detail is accurate.
