Fig 1. Example of experimental design.

Fig 1

Each screen consisted of a pair of pictures presented side by side for 3 seconds during encoding (Panel a). During recognition (Panel b), participants were asked to indicate whether they had seen the picture before. Due to the drift correction applied after each trial, the maximum length of the fixation crosshair varied between subjects. * indicates the minimum length of 1 second for each fixation crosshair presentation.
