Figure 1.

A functional run comprised 60 trials (20 trials for each of the three conditions: VSP, VNSP and baseline simulation) presented in random order. Sparse temporal sampling was used to acquire images. Trial structures of each of the three conditions were illustrated respectively. Under the visual priming condition, a priming stimulus was presented 600 ms after the scanning, then the target and masker sounds were co-presented, and terminated at the same time. The midpoint of the stimulus was presented 4.2 s prior to the next scanning. VSP, visual speech priming; VNSP, visual non-speech priming; TR, time to repeat.
