Parent-infant interactions highlight the role of parental input, considering both the quality, infant-directed speech, and quantity of interactions, adult words and communicative turns, in these interactions. However, communication is bidirectional, yet little is known about the infant's role in these interactions. This study (n = 35 4-month-old infants) explores how infant-directed speech, the number of adult words and turn-taking (both measured by the LENA system) are correlated with infants' temperament.

- The study investigates how young infants discriminate lexical tones based on their native language, age, language experience, and tone properties, revealing important insights into language learning.
- Conducted across 13 laboratories globally, it involved testing monolingual and bilingual infants aged 5 to 17 months using the same experimental setup focused on Cantonese tone contrasts.
- Results show that while infants not exposed to Cantonese effectively discriminated between non-native tone contrasts, Cantonese-learning infants did not demonstrate significant native discrimination, suggesting persistent tone sensitivity in infants and challenging current theories on perceptual narrowing.
