Note. TBW = Temporal binding window, AV Word Recognition = Whole word identification accuracy in the audiovisual condition of the speech-in-noise task at −3 or −6 dB signal-to-noise ratio (SNR), AO = Auditory-only condition of ERP task, AV = Audiovisual condition of ERP task, N1 = timeframe between 100 ms and 140 ms post-stimulus onset, P2 = timeframe between 160 ms and 240 ms, ID = Infant-directed speech, AD = Adult-directed speech, NA = Not applicable - g coefficients do not converge on acceptable stability even for estimated coefficients at 10 or more observations. See Table 2 for precise operational definitions of all variables. Bolded values are those that exceed our a priori stability criterion of g = 0.8. Underlined and bolded values reflect values that exceed the criterion at the lowest number of observations for that variable.
