Textbooks make claims like:

“The use of [child directed speech] makes it easier for infants to make a number of important speech discriminations. The exaggerated intonation of [child directed speech] and longer pauses between words also facilitates speech segmentation and discrimination between vowel sounds.”

Should you believe them? We look at:

Trainor, L. J., & Desjardins, R. N. (2002). Pitch characteristics of infant-directed speech affect infants’ ability to discriminate vowels. Psychonomic Bulletin & Review, 9(2), 335–340.
