title: Parental vocalizations and perceived immaturity in down syndrome.
abstract: Previous findings suggest that children with Down syndrome may be perceived as more youthful than other children with mental retardation. In this study whether perceptions of youthfulness can be linked to parenting behavior, in particular increased prosodic adjustments characteristic of infant-directed speech, is investigated. The prosodic characteristics of parental language targeted to children with Down syndrome and children with other etiologies of mental retardation were compared. Results show that parents of children with Down syndrome raised their voice pitch significantly more (i.e., spoke in a higher register) and spoke with a significantly wider mean pitch variance than parents of children in the comparison group. Implications are discussed for parent-child interactions in children with different genetic mental retardation syndromes.
