“…The formation of reading skills is correlated with the frequent diseases in the child during the first year of life, the cooing (vocalic comfort vocalizations) in the first year of lifewith regression in development afterward. So, the correlations between certain skills in the first, second, and the third years of TD child's life and different aspects of his development that determine the developmental trajectory [24,28] are complemented by the factor of disorder. The disorder (ASD) affects the formation of the child's speech and, accordingly, all child development and the abilities associated with speech, determining a more complex individual profile of the ASD child's development.…”

“…Predictors of speech development at 2-7 years are vowels diversity, babbling, imitation activity during the first year of a child's life, the amount of the first words at the age of 12 months, stressed vowels duration and pitch variation in mother speech addressed to child of the first year of life. Complexity of replica in dialogues, using compound phrases, ability to retell, reading skills formation, as stages of child speech development, reflect a complex dynamic process that begins at the preverbal stage of development, which are affected by the physiological condition of the child at birth [24]. In general, the trajectory of speech development in TD children corresponds to the trajectory of speech development in children living in different language environments.…”

“…Recent work highlights a positive relationship between maternal IDS prosody and later linguistic outcomes and infant attention (see Spinelli, Fasolo, & Mesman, 2017 for a review and a recent meta-analysis). These studies suggest that pitch modulation of maternal IDS has a significant influence on infants' later pre-linguistic and linguistic outcomes (e.g., D'Odoricio & Jacob, 2006;Lyakso, Frolova, & Grigorev, 2014) including their later joint attention skills (Roberts et al, 2013). Equally, studies suggest that infants respond better in the moment to stimuli that are more prosodically exaggerated (e.g., Butler, O'Sullivan, Shah, & Berthier, 2014;Niwano & Sugai, 2002a, 2002b.…”

Caregivers typically use an exaggerated speech register known as infant-directed speech (IDS) in communication with infants. Infants prefer IDS over adult-directed speech (ADS) and IDS is functionally relevant in infant-directed communication. We examined interactions between maternal IDS quality, infants’ preference for IDS over ADS, and the functional relevance of IDS at 6- and 13-months. While 6-month-olds showed a preference for IDS over ADS, 13-month-olds did not. Differences in gaze following behavior triggered by speech register (IDS vs. ADS) were found in both age groups. The degree of infants’ preference for IDS (relative to ADS) was linked to the quality of maternal IDS infants were exposed to. No such relationship was found between gaze following behavior and maternal IDS quality and infant IDS preference. Taken together, the current study speaks to a dynamic interaction between infants’ preference for different kinds of social signals and the social cues available to them.

“…Perhaps, infants who vocalize more often at 9 months are more advanced in their communicative development and end up with larger productive vocabularies at 12 months (see e.g., Donnellan et al, 2020b;Lyakso et al, 2014;McGillion et al, 2017;Werwach et al, 2021). Alternatively, parents of more vocal infants may have reported larger productive vocabularies.…”

How does social contingency facilitate vocabulary development?

Previous research shows that infants of parents who are more likely to engage in socially contingent interactions with them tend to have larger vocabularies. An open question is how social contingency facilitates vocabulary growth. One possibility is that parents who speak in response to their infants more often produce larger amount of language input, which accelerates vocabulary growth. Another possibility is that the simplicity of contingent language input is especially suitable to support early word learning. A third possibility is that more evidence of the communicative nature of language, achieved through frequent contingent responses, helps infants build a link between their own words or vocalizations and others’ behaviors. This link may lead to a better understanding of the communicative nature of language and further language advances, including vocabulary growth. To distinguish between these hypotheses, we analyzed the relations between parent–infant interactions when infants were 9 months and their vocabulary size at 12 months, using a naturalistic corpus. Our findings show that the frequency of parents’ verbal contingent responses predicts receptive vocabulary size at 12 months and this predictive relation is unlikely to be due to the amount of language input or the simplicity of language within socially contingent interactions.RESEARCH HIGHLIGHTS Infants of parents who respond to their vocalizations more often during the first year of life tend to have larger vocabularies in the second year. It is an open question what drives the predictive relation between parents’ responsiveness and infants’ vocabulary; we tested three hypotheses that offer competing explanations. More responsive parents might provide (1) more language input, (2) simpler language input, (3) more evidence of the communicative nature of language (via frequent responses). We find support for the third hypothesis; the frequency of parents’ responses predicts infants’ vocabularies above and beyond the amount and simplicity of language input.
