Vocal communication is tied to interpersonal arousal coupling in caregiver-infant dyads
<p>It has been argued that a necessary condition for the emergence of speech in humans is the ability to vocalize irrespectively of underlying affective states, but when and how this happens during development remains unclear. To examine this, we used wearable microphones and autonomic sensors to collect multimodal naturalistic datasets from 12-month-olds and their caregivers. We observed that, across the day, clusters of vocalisations occur during elevated infant and caregiver arousal. This relationship is stronger in infants than caregivers: caregivers' vocalizations show greater decoupling with their own states of arousal, and their vocal production is more influenced by the infant's arousal than their own. Different types of vocalisation elicit different patterns of change across the dyad. Cries occur following reduced infant arousal stability and lead to increased child-caregiver arousal coupling, and decreased infant arousal. Speech-like vocalisations also occur at elevated arousal, but lead to longer-lasting increases in arousal, and elicit more parental verbal responses. Our results suggest that: 12-month-old infants' vocalisations are strongly contingent on their arousal state (for both cries and speech-like vocalisations), whereas adults' vocalisations are more flexibly tied to their own arousal; that cries and speech-like vocalisations alter the intra-dyadic dynamics of arousal in different ways, which may be an important factor driving speech development; and that this selection mechanism which drives vocal development is anchored in our stress physiology.</p>

Vocal babbling in a wild parrot shows life history and endocrine affinities with human infants
<p>Vocal babbling is a critical phase in infant language development and is best understood in temperate songbirds where it occurs primarily in males at reproductive maturity and is modulated by sex steroids. Parrots of both sexes are famous vocal imitators but a vocal babbling stage has gone unnoticed and it is not clear how the endocrine system is involved. We report on vocal babbling in both sexes of nestling wild green-rumped parrotlets (<em>Forpus passerinus</em>) in Venezuela. In addition, we show that corticosterone supplements resulted in individuals with larger repertoires after treatment had ended. Results indicate parrotlets begin babbling during an earlier life history stage compared to most songbirds and one in which corticosteroids play an important role. Here we include audio files of bouts of babbling from a sample of audio-video recorded inside specially designed nest cavities and a data set of spectrographic measurements taken on each element within each bout of babbling as well as associated metadata.</p> <p> </p>

Human vocalization corpus: recordings of infant-directed and adult-directed speech and song in 21 societies
<p>This repository contains a corpus of 1615 audio recordings of speech and song collected in 21 societies, first reported in Moser et al. (2020; <a href="https://www.biorxiv.org/content/10.1101/2020.04.09.032995v5">bioRxiv</a>) and later published in Hilton & Moser et al. (2022; <a href="https://doi.org/10.1038/s41562-022-01410-x">Nature Human Behaviour</a>).

Data from: Decoding of baby calls: can adult humans identify the eliciting situation from emotional vocalizations of preverbal infants?
Preverbal infants often vocalize in emotionally loaded situations, yet the communicative potential of these vocalizations is not well understood. The aim of our study was to assess how accurately adult listeners extract information about the eliciting situation from infant preverbal vocalizations. Vocalizations of 19 infants aged 5-10 months were recorded in 3 negative (Pain, Isolation, Demand for Food) and 3 positive (Play, Reunion, After Feeding) situations. The recordings were later rated by 333 adult listeners on the scales of emotional valence and intensity. Subsequently, the listeners assigned the eliciting situations in a forced choice task. Listeners were almost perfectly able to discriminate whether a recording came from a negative or a positive situation. Their discrimination may have been based on perceived valence as they consistently assigned higher valence when listening to positive, and lower valence when listening to negative, recordings. Ability to identify the particular situation within the negative or positive realm was substantially weaker, with only three of the six situations being discriminated above chance. The best discriminated situation, Play, was associated with high perceived intensity. The weak qualitative discrimination of negative situations seemed to be based on graded perception of negative recordings, from the most intense and unpleasant (assigned to Pain) to the least intense and least unpleasant (assigned to Demand for Food). Parenthood and younger age, but not gender of listeners, had weak positive effects on the accuracy of judgments. Our results indicate that adults almost flawlessly distinguish positive and negative infant sounds, but are rather inaccurate regarding identification of the specific needs of the infant and may normally employ other sensory channels to gain this information.
Babbling in a vocal learning bat resembles human infant babbling
<p>Babbling is a production milestone in infant speech development. Evidence for babbling in non-human mammals is scarce, preventing cross-species comparisons. Here, we investigate the conspicuous babbling behavior of <em>Saccopteryx bilineata</em>, a bat capable of vocal production learning. We analyzed babbling of 20 bat pups in the field during their 3-month ontogeny and compared its features to those that characterize babbling in human infants. Our findings demonstrate that babbling in bat pups is characterized by the same eight features as babbling in human infants, including the conspicuous features reduplication and rhythmicity. These unprecedented and striking parallels in vocal ontogeny between two mammalian species offer exciting future possibilities to compare the cognitive and neuromolecular mechanisms and adaptive functions of babbling in bats and humans.</p>

Gaze orienting in the social world: An exploration of the role played by caregiving vocal and tactile behaviors in infants with visual impairment and in sighted controls
<p>This database includes the raw data linked with the paper “Gaze orienting in the social world: An exploration of the role played by caregiving vocal and tactile behaviors in infants with visual impairment and in sighted controls”, published on Brain Sciences Journal, doi: 10.5281/zenodo.11121406. In this paper we report on data on the association between maternal vocal and tactile behaviors and the gaze orientation of visually impaired (VI) infants compared to sighted controls (SI).</p> <p>Procedures</p> <p>45 infants (24 VI and 21 SI) and their mothers participated in a videorecorded 6-minute observational procedure including the well-acknowledged Face-to-Face Still-Face (FFSF) paradigm. For the purposes of this study, only the play and still episodes were analyzed. Videos were micro-analytically coded (in 2 seconds bins) for infant’s gaze orientation (unfocused GO, object GO or mother GO) and for mother’s vocal production (socio-cognitive or nurturing vocalizations) and touch behavior (pragmatic or nurturing touch).</p> <p>Analytical plan</p> <p>Correlation statistics (Spearman's rho) were used to test the associations between maternal behaviors and infants' gaze orientation in the play episode for the two groups. Two separate analyses of variance (ANOVA) were performed to compare the gaze orientation of the two groups during the play and still episodes. Two separate analyses of variance (ANOVA) were performed to compare the gaze orientation among three groups of children with different vision levels (severe, moderate, and sighted) during the play and still episodes.</p> <p>Findings in brief</p> <p>Maternal vocalizations and touch were found to influence infants' gaze orientation differently in VI infants compared SI. In particular, for VI infants no specific caregiving behaviors emerged as associated with the social orienting of attention. The group comparisons during the play episode showed that controls were predominantly oriented to the mothers, while VI infants were less socially oriented. No differences between the two groups in GO emerged during the still face episode. The visual impairment severity did not emerge as linked with social attention.</p>
