In the first days of their lives, French infants already cry in a different way to German babies. This was the result of a study by researchers from the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig, the Centre for Pre-language Development and Developmental Disorders (ZVES) at the University Clinic Würzburg, and the Laboratory of Cognitive Sciences and Linguistics at the Ecole Normale Supérieure in Paris. In this study, the scientists compared recordings of 30 French and 30 German infants aged between two and five days old.
