Figure 1. Design of the Backward Masking Task.

Figure 1

(A) Two neutral target faces were shown prior to the start of each run in which participants were instructed to remember and determine whether subsequent face presentations matched the identity. (B) Two faces were shown as part of each trial presentation. Examples of the masked faces event types (SN, HN, NN) are shown with “N” placeholders to indicate the presentation of a neutral face.

HN = Happy/Neutral face presentation; ISI = interstimulus interval; NN = Neutral/Neutral face presentation; SN = Sad/Neutral face presentations
