Figure 1.

Schematic timeline of a typical trial in the ‘unaware’ condition. The image was presented to one eye (randomized from trial to trial) and the dynamic CFS mask was presented to the other. In the ‘aware’ condition, the image was still presented monocularly, but no CFS mask was presented to the other eye. The CFS mask changed dynamically at a rate of 10 Hz. A loud noise burst (50 ms; 106 dB) was presented at a random time between 3 s and 4 s after trial onset. Brief dot displays were presented before and after the noise burst. Each trial concluded with three questions that were answered using the computer keyboard: First, how many dots were shown in total? (1, 2 or 3). Second, was the picture intact or scrambled? (1–intact and 2–scrambled). Third, what is your confidence in your intact/scrambled judgement? (1–guessing 2–not sure and 3–certain). Dots have been enlarged for display clarity. Image for illustrative purposes; the experiment used images drawn from IAPS database (Lang et al. 2008). Source: Available from https://www.123rf.com/photo_29940472_stock-photo.html, ©123rf.com.
