A neural marker of rapid discrimination of facial expression in 3.5 and 7-month-old infants

Little is known about infants' ability to rapidly discriminate a facial expression against many others. Here, we investigated the development of facial expression discrimination in infancy with fast periodic visual stimulation coupled with scalp electroencephalography (EEG). EEG was recorded in 3.5- and 7-month-old infants (n=18 per group) displayed with an expressive (disgust or happy) or neutral female face at a base stimulation frequency of 6 Hz. Pictures of the same individual randomly expressing other expressions (either anger, disgust, fear, happiness, sadness, or neutrality) were introduced every 6 stimuli (i.e., at 6/6 = 1 Hz) to directly isolate a discrimination response between th…

Maternal odor selectively enhances rapid face categorization from natural images in the 4-month-old infant brain

Maternal odor selectively enhances the categorization of face(like) stimuli in the 4 month-old infant brain

Présentation Poster; International audience; In the 4-month-old infant brain, the visual categorization of natural face images is enhanced by concomitant maternal odor (Leleu et al., 2019), providing support for the early perception of congruent associations between co-occurring inputs from multiple senses. Here, we further explore whether this maternal odor effect is selective to faces or if it can be explained by a more general influence of salient odor cues on the perception of any visual object category. In Experiment 1, scalp electroencephalogram was recorded during a fast periodic visual stimulation (FPVS-EEG) while 4-month-old infants were exposed to the maternal vs. a control odor. …

Expert en visages: sommes-nous programmés pour reconnaître les visages ?

International audience; Experts en visages, nous le sommes tous : chacun d’entre nous est capable de reconnaître et de mémoriser des centaines de visages. Mais quel est le processus cognitif à l’œuvre, qui fait que le nourrisson est capable de reconnaître le visage de sa mère ? Selon quels phénomènes, dès le plus jeune âge, le visage prend-il une telle importance ? Sommes-nous programmés génétiquement à reconnaître les visages ou est-ce lié à un apprentissage ? Quelles sont les pathologies qui ont un impact sur la reconnaissance du visage ?À travers ce livre, l’auteur fait une synthèse des recherches sur le visage, qu’il aborde sous les aspects à la fois cognitifs et neuropsychologiques. Il…
