“…The fact that we can predict both the assessment of a physiology expert from behavioural features and the assessment of external observers from physiological features shows that there is some coherence between behavioural and physiological cues when one is experiencing stress despite the lack of agreement between EOA and PEA annotations (Tables 6 and 7). This interplay between physiology and behaviour that we observe in our results is coherent with several works on facial expressions [64], [65], [66], emotions [67], and stress [36], [68]. However, for all 3 assessment sets considered, the combination of behavioural and physiological features provided the best results.…”

“…Finally, the behavioural perspective investigates the impact of stress on human and animal behaviour both at individual and group levels [34], [35]. Both transfer of ethological research to human behaviour and social signal processing lead researchers to a promising approach of behavioral measure of stress in non human primates [34] and more recently in human subjects [35], [36]. Engaging in displacement behaviors such as scratching, face touching and lip biting have been associated with stressfull experiences and may give more valuable information about the subjects emotional state than verbal statements and verbal expressions [34].…”

International audienceStress is a complex phenomenon that impacts the body and the mind at several levels. It has been studied for more than a century from different perspectives, which result in different definitions and different ways to assess the presence of stress. This paper introduces a methodology for analyzing multimodal stress detection results by taking into account the variety of stress assessments. As a first step, we have collected video, depth and physiological data from 25 subjects in a stressful situation: a socially evaluated mental arithmetic test. As a second step, we have acquired 3 different assessments of stress: self-assessment, assessments from external observers and assessment from a physiology expert. Finally, we extract 101 behavioural and physiological features and evaluate their predictive power for the 3 collected assessments using a classification task. Using multimodal features, we obtain average F1 scores up to 0.85. By investigating the composition of the best selected feature subsets and the individual feature classification performances, we show that several features provide valuable information for the classification of the 3 assessments: features related to body movement, blood volume pulse and heart rate. From a methodological point of view, we argue that a multiple assessment approach provide more robust results

“…Additionally, during dyadic interaction, caregivers are sensitive to infant vocalization, and their own vocal production regulates that of the infant [ 20 , 21 ]. Parents may also use infant-directed speech (IDS) that conveys linguistic as well as emotional components.…”

“…Studies have used the SFP to address the effects of separation on infants' physiology and behaviour, to test the consequences of early deprivation, and to measure infant attachment [ 23 , 28 , 29 ]. Similarly, the SFP has been used to tap infant stress physiology and has shown to increase infants cortisol levels [ 21 ]. However, this increase of cortisol is not systematic, and SF's stressful effects may be attenuated by using affectionate touch [ 7 ].…”

Pre-linguistic infants employ complex communicative loops to engage mothers in social exchanges and repair interaction ruptures

Language has long been identified as a powerful communicative tool among humans. Yet, pre-linguistic communication, which is common in many species, is also used by human infants prior to the acquisition of language. The potential communicational value of pre-linguistic vocal interactions between human infants and mothers has been studied in the past decades. With 120 dyads (mothers and three- or six-month-old infants), we used the classical Still Face Paradigm (SFP) in which mothers interact freely with their infants, then refrain from communication (Still Face, SF), and finally resume play. We employed innovative automated techniques to measure infant and maternal vocalization and pause, and dyadic parameters (infant response to mother, joint silence and overlap) and the emotional component of Infant Directed Speech (e-IDS) throughout the interaction. We showed that: (i) during the initial free play mothers use longer vocalizations and more e-IDS when they interact with older infants and (ii) infant boys exhibit longer vocalizations and shorter pauses than girls. (iii) During the SF and reunion phases, infants show marked and sustained changes in vocalizations but their mothers do not and (iv) mother–infant dyadic parameters increase in the reunion phase. Our quantitative results show that infants, from the age of three months, actively participate to restore the interactive loop after communicative ruptures long before vocalizations show clear linguistic meaning. Thus, auditory signals provide from early in life a channel by which infants co-create interactions, enhancing the mother–infant bond.
