The literature indicates that children show reduced sensitivity to visual speech from kindergarten to adolescence. We hypothesized that this pattern reflects the effects of complex tasks and a growth period with harder-to-utilize…

Speech perception involves the integration of auditory and visual articulatory information, and thus requires the perception of temporal synchrony between this information.
