Binding is key in multisensory perception. This study investigated the audio-visual temporal binding window in 4-, 5-, and 6-year-old children (total N=120). Children watched a person uttering a syllable whose auditory and visual components were either temporally synchronized or desynchronized by 366, 500, or 666 ms. They were asked whether the voice and face went together (Experiment 1) or whether the desynchronized videos differed from the synchronized one (Experiment 2). Four-year-olds detected the 666 ms asynchrony, 5-year-olds detected the 666 and 500 ms asynchrony, and 6-year-olds detected all asynchronies. These results show that the audio-visual temporal binding window narrows slowly during early childhood and that it is still wider at six years of age than in older children and adults.

Early Experience & Multisensory Perceptual Narrowing (2014, background): “…to rely on them for the perception of the multisensory coherence of a broad variety of multisensory events including light flashes and beeping sounds, moving and impacting objects, and audiovisual speech (Dixon & Spitz, 1980; Hillock-Dunn & Wallace, 2012; Lewkowicz, 2010; Lewkowicz & Flom, 2013).”
The temporal binding window for audiovisual speech: Children are like little adults (2016, background): “Recent work from Lewkowicz & Flom (2013) investigating audiovisual asynchrony detection of speech in 4-, 5-, and 6-year old children also provides evidence of ongoing refinement of multisensory processing of complex signals during childhood.”
