“…are consistent with previous study that found higher initiation rate of 25-37 month-old children than parents (VanDam et. al., 2022) and it seems to suggest that older children had more locus of control in conversations as a result of improved language abilities.…”

“…These findings suggest the positive effect of caregiver's initiative role, which seems to be more important than children's initiation of interactions. However, given that children tend to be more active in their own initiated conversation than when they are the respondent (Ko et al, 2016) and that older children (25-37 month-old) tend to initiate conversations more frequently than parents (VanDam et. al., 2022), further investigation on the role of initiator effect in language development may provide practical guidelines on how to facilitate caregiver-child interaction towards a better language outcome.…”

This study examined the caregiver's role as an initiator of conversational interactions and the effects of such a role on infants’ word learning. 228 daylong LENA recordings from 141 Korean mother-child dyads (60 girls & 81 boys aged 7-30 months) were analysed. Both the child and mother showed more engaging patterns of speech behavior in their own-initiated conversational blocks across ages. Analysis of 40 children at an early speech stage (15 girls; aged 14-15 months) showed that mothers of children with higher CDI percentile initiated more conversation and responded more quickly. Mothers of at-risk children provided less response to the child’s vocalization than typically developing children, and mothers who provided a greater ratio of response also initiated more conversation.

“…Our study then addresses infant vocalization in both social and nonsocial circumstances, observed naturalistically in all-day recordings, which have made it possible during more than a decade to assess vocal patterns with greater ecological validity than was possible in the past [79][80][81][82][83]. The data were coded in 5-min segments drawn from the recordings.…”

Perspectives on the origin of language: Infants vocalize most during independent vocal play but produce their most speech-like vocalizations during turn taking

et al. 2022

A growing body of research emphasizes both endogenous and social motivations in human vocal development. Our own efforts seek to establish an evolutionary and developmental perspective on the existence and usage of speech-like vocalizations (“protophones”) in the first year of life. We evaluated the relative occurrence of protophones in 40 typically developing infants across the second-half year based on longitudinal all-day recordings. Infants showed strong endogenous motivation to vocalize, producing vastly more protophones during independent vocal exploration and play than during vocal turn taking. Both periods of vocal play and periods of turn-taking corresponded to elevated levels of the most advanced protophones (canonical babbling) relative to periods without vocal play or without turn-taking. Notably, periods of turn taking showed even more canonical babbling than periods of vocal play. We conclude that endogenous motivation drives infants’ tendencies to explore and display a great number of speech-like vocalizations, but that social interaction drives the production of the most speech-like forms. The results inform our previously published proposal that the human infant has been naturally selected to explore protophone production and that the exploratory inclination in our hominin ancestors formed a foundation for language.

“…Even at 12 months, however, caregivers tend to verbally respond more often to infants' object‐directed gestures (e.g., pointing) than to their object‐directed vocalizations (Wu & Gros‐Louis, 2015), potentially attenuating a LENA‐derived estimate of infant‐initiated conversations even at that age. A recent analysis suggests that by 30 months, children are initiating significantly more conversations than are their caregivers (VanDam et al., 2022); however, the extent to which this is driven by differences in child vocalizations from age 6–30 months (either in number or kind), by caregivers responding to a greater proportion of child bids, or by a combination of these is unknown. In addition, prior research suggests that predictors of language outcomes depend on the age at which children are assessed.…”

Infants who experience more adult‐initiated conversations have better expressive language in toddlerhood

To understand how infants become engaged in conversations with their caregivers, we examined who tends to initiate conversations between adults and infants, differences between the features of infant-and adult-initiated conversations, and whether individual differences in how much infants engage in infant-or adult-initiated conversations uniquely predict later language development. We analyzed naturalistic adult-infant conversations captured via passive recording of the daily environment in two samples of 6-month-old infants. In Study 1, we found that at age 6 months, infants typically engage in more adult-than infant-initiated conversations and that adult-initiated conversations are, on average, longer and contain more adult words. In Study 2, we replicated these findings and, further, found that infants who engaged in more adult-initiated conversations in infancy had better expressive language at age 18 months. This association remained significant when accounting for the number of infantinitiated conversations at 6 months. Our findings indicate that early interactions with caregivers can have a lasting impact on children's language development, and that the extent to which parents initiate interactions with their infants may be particularly important.
