  • Participants are first shown the movie title for 2.5 seconds and then shown the movie.

Free Recall

  • Participants are prompted with a movie title for 7.5 seconds. During this time, the participant indicates if they are able to recall the movie associated with the title.
  • If they are unable to recall the movie, they are then shown an image cue for 3 seconds.
  • A fixation cross is then shown, and the participant speaks freely into a microphone for an unlimited amount of time to recall as many details as possible from the movie.
  • Conditions: 4 are from that current session previously shown in the encoding task, 2 are repeated every session, and 2 are from the previous session.
