Fig. 1

Schematic representation of a trial in the audiovisual matching task. Note that separate timelines are shown for the video and audio tracks. The video of articulation was congruent in half of all trials (e.g., participants saw the piglet silently articulate “toys” after hearing “toys” at the start of the trial) and incongruent in the other half of trials (e.g., participants saw the piglet silently articulate “bus” after hearing “toys” at the start of the trial). The onset of articulation was used as time 0 for the N400, LPC, and anterior negativity ERP averages. The onset of the pictures was used at time 0 for the visual P1, N1, and P2 ERP averages elicited by pictures, while the onset of the static picture of the talker’s face, prior to the onset of articulation, was used as time 0 for the visual P1, N1, and P2 ERP averages elicited by the talker’s face.
