Researchers have been studying the cry acoustics of six-month-old infants. At-risk infants produced pain related cries with higher and more variable fundamental frequency (commonly referred to as "pitch") as compared to low-risk infants. A small number of the at-risk infants were later diagnosed with an autism spectrum disorder at 36 months of age.
