Perception of Cry Characteristics in 1-Month-Old Infants Later Diagnosed with Autism Spectrum Disorder.

This study investigates parental perceptions of cries of 1-month-old infants later diagnosed with autism spectrum disorder (ASD) and non-ASD controls. Parents of children with and without ASD listened to cry recordings of infants later diagnosed with ASD and comparison infants and rated them on cry perception scales. Parents completed the Broad Autism Phenotype Questionnaire (BAPQ) to assess the potential relations between traits associated with autism and cry perception. Across parents, ASD infant cries were rated as more distressed, less typical, and reflecting greater pain, with no significant differences between parent groups. Parents of children with ASD scored higher on the BAPQ compared to parents of children without ASD. Follow up analyses explored the relations between BAPQ score and cry ratings.
