title: Neural patterns to speech and vocabulary growth in American infants.
abstract: We report infant auditory event-related potentials to native and foreign contrasts. Foreign contrasts are discriminated at 11 months of age, showing significant differences between the standard and deviant over the positive (P150-250), or over the negative (N250-550) part of the waveform. The amplitudes of these deflections have different amplitude scalp distributions. Infants were followed up longitudinally at 18, 22, 25, 27 and 30 months for word production. The infant speech discriminatory P150-250 and N250-550 are different components with different implications for later language development.
