Extended Data Fig. 6: Relationship between habituation criteria and the PN and VOE in individual infants from familiarization studies.

(a) and (b) show boxplots of the (a) PN and (b) VOE effects in log seconds, broken down by whether infants met a standard habituation criteria by the end of the familiarization phase (21 studies, N = 603 infants). The centre of the box indicates the median, the bounds of the box correspond to the 25th and 75th percentiles (the interquartile range, or IQR), and the whiskers extend to the minima and maxima (up to 1.5 IQRs from the 25th and 75th percentiles). Data beyond the end of the whiskers are plotted in dark grey.
