Comparison between the newborn results reported here, and previous newborn selectivity results (i.e., dissimilarity in strength of responses across conditions).

Localization and channel number provide information on the one channel whose data was used for the effect size. In all cases, the effect size is Cohen's d indicating selectivity of responses, in the sense of greater reaction to Condition 1 than Condition 2. For comparability with the previous research, the effect size for our study comes from the native speech versus scrambled controls.
