Le traitement des expressions faciales au cours de la première année : développement et rôle de l'olfaction

The first year of life is critical for the development of the abilities to process facial expressions. Olfaction and expressions are both strongly linked to each other, and it is well known that infants are able to multisensorially integrate their environment as early as birth. However, most of the studies interested in multisensory processing of facial expressions are restricted to the investigation of audio-visual interactions.In this thesis, we firstly aimed to resolve different issues concerning the ontogenesis of infants’ ability to process facial expressions. Our results allowed to specify the development of visual exploratory strategies of facial emotions along the first year of life…

Three-month-old infants’ sensitivity to horizontal information within faces

Horizontal information is crucial to face processing in adults. Yet the ontogeny of this preferential type of processing remains unknown. To clarify this issue, we tested 3-month-old infants' sensitivity to horizontal information within faces. Specifically, infants were exposed to the simultaneous presentation of a face and a car presented in upright or inverted orientation while their looking behavior was recorded. Face and car images were either broadband (UNF) or filtered to only reveal horizontal (H), vertical (V) or this combined information (HV). As expected, infants looked longer at upright faces than at upright cars, but critically, only when horizontal information was preserved in …

Mimicking emotions: how 3–12-month-old infants use the facial expressions and eyes of a model

International audience; While there is an extensive literature on the tendency to mimic emotional expressions in adults, it is unclear how this skill emerges and develops over time. Specifically, it is unclear whether infants mimic discrete emotion-related facial actions, whether their facial displays are moderated by contextual cues and whether infants’ emotional mimicry is constrained by developmental changes in the ability to discriminate emotions. We therefore investigate these questions using Baby-FACS to code infants’ facial displays and eye-movement tracking to examine infants’ looking times at facial expressions. Three-, 7-, and 12-month-old participants were exposed to dynamic faci…

Visual exploration and discrimination of emotional facial expressions in 3-, 7- and 12-month-old infants

The first year of life is critical in the development of the abilities to process facial expressions. Numerous studies have investigated discrimination and categorization of distinct facial expressions of emotion. However, infants' visual exploratory strategies of these facial expressions and their developmental paths remain unclear. The perfection of eye movement tracking systems makes now the detailed analysis of facial exploration of faces feasible, and hence facilitates the identification of the features in facial expressions which infants focus on. In this study, oculometric parameters of 3- (n=36), 7- (n=66) and 12-month-old infants (n=59) were collected while facial expressions were …
