We examined the course of caregiver (CG) motherese and the course of the infant's response based on home movies from two single cases: a boy with typical development (TD) and a boy with autistic development (AD). We first blindly assessed infant CG interaction using the Observer computer-based coding procedure, then analyzed speech CG production us...

Various aspects of motherese also known as infant-directed speech (IDS) have been studied for many years. As it is a widespread phenomenon, it is suspected to play some important roles in infant development. Therefore, our purpose was to provide an update of the evidence accumulated by reviewing all of the empirical or experimental studies that hav...

Whether development of autism impacts the interactive process between an infant and his/her parents remains an unexplored issue. Using computational analysis taking into account synchronic behaviors and emotional prosody (parentese), we assessed the course of infants' responses to parents' type of speech in home movies from typically developing (TD...

To assess whether taking into account interaction synchrony would help to better differentiate autism (AD) from intellectual disability (ID) and typical development (TD) in family home movies of infants aged less than 18 months, we used computational methods. First, we analyzed interactive sequences extracted from home movies of children with AD (N...
Article
Autism is a well-defined clinical syndrome after the second year of life, but information on autism in the first two years of life is still lacking. The study of home videos has described children with autism during the first year of life as not displaying the rigid pattern typical of later symptoms. Therefore, developmental/environmental factors a...
Thesis
Différemment des bébés typiques, qui expriment un intérêt pour la communication, les bébés à devenir autistique se caractérisent par la présence d’anomalies dans les interactions sociales et dans la communication. Cette recherche se focalise sur le « mamanais », un langage utilisé par les adultes lorsqu’ils s’adressent aux bébés. Caractérisé par un...

The current study reviewed all prior studies conducted on family home movies of infants who would be later diagnosed with autism spectrum disorder (ASD). Out of 41 original reports found since 1975, we retained 18 studies (317 films, maximum), sorted according to their methodological design using a quality grid. In the first 2 years of life, signs...

This paper deals with emotional speech detection in home movies. In this study, we focus on infant-directed speech also called "motherese" which is characterized by higher pitch, slower tempo, and exaggerated intonation. In this work, we show the robustness of approaches to automatic discrimination between infant-directed speech and normal directed...
