“…Smiling increases in frequency over the first weeks up to the point of becoming a social smile at around age 2 months (Lavelli & Fogel, 2005). We saw no change in frequency of vocalizations across time in the youngest babies, which is to be expected because this behaviour starts its growth curve in the second month and increasing to the sixth (Hsu et al, 2001). However, we could have expected an association between the timing of observation and vocalizations for the older babies.…”

“…Smiles and vocalizations are present at birth and increase in frequency over the first months largely as the result of parental reactions (Hsu, Fogel, & Messinger, 2001;Mendes & Seidl-de-Moura, 2014). At first the smile is rare, but it increases in frequency over the first weeks up to the point of becoming a social smile at around age 2 months (Lavelli & Fogel, 2005).…”

Vocalizations start their growth curve in the second month and increasing to the sixth (Hsu et al, 2001). Babies also manifest mouth movements (opening or puckering, tongue protrusion) from birth in response to similar movements by the adult, thus showing the neonate's precocious imitative abilities (Nagy, Pilling, Orvos, & Molnar, 2013).…”

The present pilot study focuses on the adaptive processes of babies who are placed during their first months of life. It used an ethological approach to explore the behavioural adjustment of 19 infants from their arrival in placement through their first 6 weeks in Residential Care (RC; France), a Foster Family (FF; Québec) or an Infant-Mother Centre (IMC; Québec). Direct observations were conducted once a week during feeding sessions. Observed behaviours were as follows: sleep-wake state, self-soothing, burp, visual exploration, motor activity, facial and vocal expressions. Then, a Kruskal-Wallis test was conducted to examine differences in babies' adaption as a function of placement setting. Results showed that, in RC, the duration of the post-feeding phase is the shortest. Moreover, these institutionalized babies showed the most modes of self-protection and the fewest vocalizations. By contrast, babies placed in the IMC spent the least time in withdrawal, expressed motor activity more regularly and were never placed back in their recliner before burping. Larger differences appear comparing placement in RC and that in the IMC, the placement in FF showing intermediate results.

“…In spite of the strong evidence for endogenously driven human infant vocalizations, the primary emphasis in prior research has long been on social interaction as the force driving human infant sounds (Anderson et al, 1977; Trevarthen, 1979; Keller and Schőlmerich, 1987; Fernald, 1992; Stoel-Gammon, 1998; Hsu et al, 2001; Gros-Louis et al, 2006, 2014; Goldstein and Schwade, 2008; Menyuk et al, 2014). The emphasis on interactivity is understandable given that content of particular languages must be learned through listening to caregivers and interacting with them.…”

Language Origins Viewed in Spontaneous and Interactive Vocal Rates of Human and Bonobo Infants

et al. 2019

View full text Add to dashboard Cite

From the first months of life, human infants produce “protophones,” speech-like, non-cry sounds, presumed absent, or only minimally present in other apes. But there have been no direct quantitative comparisons to support this presumption. In addition, by 2 months, human infants show sustained face-to-face interaction using protophones, a pattern thought also absent or very limited in other apes, but again, without quantitative comparison. Such comparison should provide evidence relevant to determining foundations of language, since substantially flexible vocalization, the inclination to explore vocalization, and the ability to interact socially by means of vocalization are foundations for language. Here we quantitatively compare data on vocalization rates in three captive bonobo ( Pan paniscus ) mother–infant pairs with various sources of data from our laboratories on human infant vocalization. Both humans and bonobos produced distress sounds (cries/screams) and laughter. The bonobo infants also produced sounds that were neither screams nor laughs and that showed acoustic similarities to the human protophones. These protophone-like sounds confirm that bonobo infants share with humans the capacity to produce vocalizations that appear foundational for language. Still, there were dramatic differences between the species in both quantity and function of the protophone and protophone-like sounds. The bonobo protophone-like sounds were far less frequent than the human protophones, and the human protophones were far less likely to be interpreted as complaints and more likely as vocal play. Moreover, we found extensive vocal interaction between human infants and mothers, but no vocal interaction in the bonobo mother–infant pairs—while bonobo mothers were physically responsive to their infants, we observed no case of a bonobo mother vocalization directed to her infant. Our cross-species comparison focuses on low- and moderate-arousal circumstances because we reason the roots of language entail vocalization not triggered by excitement, for example, during fighting or intense play. Language appears to be founded in flexible vocalization, used to regulate comfortable social interaction, to share variable affective states at various levels of arousal, and to explore vocalization itself.

“…In addition, although infants produce both cries and protophones from birth (Nathani et al, 2006), most research appears so far to have attempted to investigate caregiver-infant interaction exclusively with speech-like sounds, which they have generally termed “non-distress” sounds (e.g., Hsu et al, 2001). Kaye and Fogel (1980) treated distress sounds somewhat differently from other studies, mentioning that “less extreme fussiness was considered a normal part of the interaction” (p. 455).…”

The Origin of Protoconversation: An Examination of Caregiver Responses to Cry and Speech-Like Vocalizations

2018

View full text Add to dashboard Cite

Turn-taking is a universal and fundamental feature of human vocal communication. Through protoconversation, caregivers play a key role for infants in helping them learn the turn-taking system. Infants produce both speech-like vocalizations (i.e., protophones) and cries from birth. Prior research has shown that caregivers take turns with infant protophones. However, no prior research has investigated the timing of caregiver responses to cries. The present work is the first to systematically investigate different temporal patterns of caregiver responses to protophones and to cries. Results showed that, even in infants' first 3 months of life, caregivers were more likely to take turns with protophones and to overlap with cries. The study provides evidence that caregivers are intuitively aware that protophones and cries are functionally different: protophones are treated as precursors to speech, whereas cries are treated as expressions of distress.
