“…However both may be tightly connected in the sense that "vocal correlates of motivation imply an underlying emotion" [see review Briefer, 2012]. Changes in vocal parameters in response to emotional states are expected in mammals [Coss et al, 2007;Scheiner & Fisher, 2011;Scherer & Kappas, 1988] in line with the motivationalstructural rules of acoustic signals [August & Anderson, 1987;Manser, 2010;Morton, 1977]. Adult chimpanzee screams indeed varied acoustically reflecting the motivational state of the caller [Siebert & Parr, 2003].…”

A large array of communication signals supports the fission/fusion social organization in chimpanzees, and among them the acoustic channel plays a large part because of their forest habitat. Adult vocalizations convey social and ecological information to their recipients allowing them to obtain cues about an ongoing event from calls only. In contrast to adult vocalizations, information encoded in infant calls had been hardly investigated. Studies mainly focused on vocal development. The present article aims at assessing the acoustic cues that support individual identity coding in infant chimpanzees. By analyzing recordings performed in the wild from seven 3-year-old infant chimpanzees, we showed that their calls support a well-defined individual vocal signature relying on spectral cues. To assess the reliability of the signature across the calls of an individual, we defined two subsets of recordings on the basis of the characteristics of the frequency modulation (whimpers and screams) and showed that both call types present a reliable vocal signature. Early vocal signature may allow the mother and other individuals in the group to identify the infant caller when visual contact is broken. Chimpanzee mothers may have developed abilities to cope with changing vocal signatures while their infant, still vulnerable, gains in independence in close habitat.

“…To support these complex social interactions, humans are equipped with a powerful tool-the face (although see also research on voice and body posture, e.g., Atkinson et al 2004, Belin et al 2008, Cordaro et al 2015, Dael et al 2012, de Gelder 2009, Grezes et al 2007, Pollick et al 2001, Roether et al 2009, Scheiner & Fischer 2011. As a rich source of information, the human face can elicit myriad immediate social judgments-for example, about identity (e.g., Gauthier et al 1999, pattern of a happy facial expression is transmitted through the medium of light (i.e., photons) to the visual system of another human.…”

As a highly social species, humans are equipped with a powerful tool for social communication-the face. Although seemingly simple, the human face can elicit multiple social perceptions due to the rich variations of its movements, morphology, and complexion. Consequently, identifying precisely what face information elicits different social perceptions is a complex empirical challenge that has largely remained beyond the reach of traditional methods. In the past decade, the emerging field of social psychophysics has developed new methods to address this challenge, with the potential to transfer psychophysical laws of social perception to the digital economy via avatars and social robots. At this exciting juncture, it is timely to review these new methodological developments. In this article, we introduce and review the foundational methodological developments of social psychophysics, present work done in the past decade that has advanced understanding of the face as a tool for social communication, and discuss the major challenges that lie ahead.

“…Does volubility across vocal types vary with circumstance, suggesting that different speech-like sounds may have consistently different functions? Until recently, research had provided a preliminary answer to this question, suggesting considerable flexibility of usage of sounds across circumstances (Papaeliou, Minadakis, & Cavouras, 2002; Hsu, Iyer, & Fogel, 2013; Scheiner & Fischer, 2011; Scheiner, Hammerschmidt, Jurgens, & Zwirner, 2006; Stark, Bernstein, & Demorest, 1993; Oller, 2000). A recent study, however, illustrates more conclusively that the human infant shows extraordinary flexibility of usage of vocal types across different circumstances, apparently much greater flexibility than seen in any other primate at any age (Oller et al, 2013).…”

Examination of infant vocalization patterns across interactive and noninteractive contexts may facilitate better understanding of early communication development. In the current study, with 24 infant-parent dyads, infant volubility increased significantly when parent interaction ceased (presenting a “still face,” or SF) after a period of normal interaction (“face-to-face,” or FF). Infant volubility continued at the higher rate than in FF when the parent re-engaged (“reunion,” or RE). Additionally, during SF, the variability in volubility across infants decreased, suggesting the infants adopted relatively similar rates of vocalization to re-engage the parent. The pattern of increasing volubility in SF was seen across all of the most common speech-like vocal types of the first half-year of life (e.g., full vowels, quasivowels, squeals, growls). Parent and infant volubility levels were not significantly correlated. The findings suggest that by six months of age infants have learned that their vocalizations have social value and that changes in volubility can affect parental engagement.
