Summary

Confirmatory feedback during interrogations can lead witnesses to falsely remember fabricated details as real. This study explores whether feedback changes memory representations or just beliefs about events.

Area of Science:

  • Cognitive Psychology
  • Forensic Psychology
  • Memory Studies

Background:

  • Witnesses may confabulate details during interrogations.
  • Experimenter affirmation of false accounts can increase false recognition.
  • The mechanism of this 'confirmatory feedback effect' is not fully understood.

Purpose of the Study:

  • To investigate whether confirmatory feedback alters mental representations of confabulated events.
  • To determine if feedback changes beliefs about the event's reality.
  • To examine the phenomenological experience of false recognition.

Main Methods:

  • Participants confabulated event details under simulated interrogation.
  • Experimenters provided verbal affirmation for some false responses.

Related Experiment Videos

  • Participants later judged phenomenological experience associated with recognizing confabulated events.

    • Main Results:

    • Confirmatory feedback enhances the likelihood of false recognition.
    • The study aims to differentiate between changes in memory representation and belief.

    Conclusions:

    • Further research is needed to clarify the cognitive mechanisms behind the confirmatory feedback effect.
    • Understanding these mechanisms is crucial for accurate eyewitness testimony.
