According to the perceptual narrowing hypothesis, older infants look longer towards speech in a native language than towards a non-native language. We presented speech in English, Spanish, and mis-matched English and Spanish speech, and recorded looking-time towards the speech. Results suggest that the synchrony of speech plays a strong role in infants' attention to speech, whereas nativeness of language does not.
