Neural mismatch indices of vowel discrimination in monolingually and bilingually exposed infants: Does attention matter?

► We explored the functional nature of infant neural mismatch responses (MMRs) to an English vowel change. ► We compared MMRs in the internal versus final positions of a stimulus sequence. ► Increased negativity of the MMR was found in the final position. ► We hypothesized that infants paid more attention to the vowels in the final position.
