From: Audio-visual combination of syllables involves time-sensitive dynamics following from fusion failure
(A) Typical time course of audio-visual stimuli. (B) Example trials from experiments 1 and 2. Experiment 1: trials started with a 1 s fixation period, followed by a videoclip showing a speaker pronouncing a syllable. Participants had to repeat the perceived syllable as fast as possible. Experiment 2: trials started with a 1 s written syllable, followed by a short videoclip showing a speaker pronouncing a syllable. Participants were instructed to press a button as fast as possible if the written syllable matched the syllable they perceived from the AV videoclip. (C) Experimental conditions used in the behavioural and MEG experiments. The same three conditions, labelled ‘congruent’, ‘fusion’, and ‘combination’ were used in the behavioural and neuroimaging experiments. In each condition, stimuli combined a video track and an audio track, and used two consonant families: either ‘bdg’ or ‘ptk’. Right panel: the answer of interest (expected response depending on the exact AV stimulus integration) is shown in bold-italic. Image made using Microsoft PowerPoint, version 16.41.
