Aims We aim to (a) overview the literature on RtN in different developmental disorders during the first 24 months of life, and (b) report comparative data on RtN across syndromes. Methods and procedures In Part 1, a literature search, focusing on RtN in children during the first 24 months of life with developmental disorders, identified 23 relevant studies. In Part 2, RtN was assessed utilizing retrospective video analysis for infants later diagnosed with ASD, RTT, or FXS, and typically developing peers. Outcomes and results Given a variety of methodologies and instruments applied to assess RtN, 21/23 studies identified RtN as atypical in infants with a developmental disorder. We observed four different developmental trajectories of RtN in ASD, RTT, PSV, and FXS from 9 to 24 months of age. Between-group differences became more distinctive with age. Conclusions and implications RtN may be a potential parameter of interest in a comprehensive early detection model characterising age-specific neurofunctional biomarkers associated with specific disorders, and contribute to early identification."],["dc.identifier.doi","10.1016/j.ridd.2018.04.004"],["dc.identifier.pmid","29655507"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/66133"],["dc.language.iso","en"],["dc.relation.issn","0891-4222"],["dc.title","Response to name and its value for the early detection of developmental disorders: Insights from autism spectrum disorder, Rett syndrome, and fragile X syndrome.

Despite a few reports about atypicalities in the speech-language development of infants and toddlers with RTT, a detailed analysis of the pre-linguistic vocalisation repertoire of infants with RTT is yet missing. Based on home video recordings, we analysed the vocalisations between 9 and 11 months of age of three female infants with typical RTT and compared them to three age-matched typically developing (TD) female controls. The video material of the infants had a total duration of 424 min with 1655 infant vocalisations. For each month, we (1) calculated the infants’ canonical babbling ratios with CBR\r\n UTTER\r\n , i.e., the ratio of number of utterances containing canonical syllables to total number of utterances, and (2) classified their pre-linguistic vocalisations in three non-canonical and four canonical vocalisation subtypes. All infants achieved the milestone of canonical babbling at 9 months of age according to their canonical babbling ratios, i.e. CBR\r\n UTTER\r\n  ≥ 0.15. We revealed overall lower CBRs\r\n UTTER\r\n  and a lower proportion of canonical pre-linguistic vocalisations consisting of well-formed sounds that could serve as parts of target-language words for the RTT group compared to the TD group.
