Schematic summary of the paradigm. The paradigm comprises a cued reflection period followed by perception of a photograph to the cued person for the indicated periods of time. For each condition, the same standardized set of photographs was shown in a random order. The subjects were instructed to reflect on the cued person in the ‘reflection’ period and to view the photograph during the ‘perception’ period (photos reprinted here with explicit consent of the shown subjects).
