Trial procedure. Depending on the presentation condition, two identical stimuli (faces), stimulus and mondrians, or empty background and mondrians were presented to the left and right eye respectively. The spatial position of the stimulus was then to be retained for a 5 or 15 s delay period, until a probe prompted the participants to respond whether or not the probe's position matched the previously presented position. Next, the participants gave an estimate of their perceptual experience of the stimulus. Finally, they responded whether or not a stimulus had been present. DMS, delayed match-to-sample task; PAS, perceptual awareness scale; (i), probe matches presentation; (ii), probe does not match presentation.
