Emotional Movement Kinematics Guide Twelve-Month-Olds' Visual, but Not Manual, Exploration.

The ability to recognize and act on others' emotions is crucial for navigating social interactions successfully and learning about the world. One way in which others' emotions are observable is through their movement kinematics. Movement information is available even at a distance or when an individual's face is not visible.

You can't play with us: First-person ostracism affects infants' behavioral reactivity.

Ostracism negatively affects fundamental psychological needs, induces physiological and behavioral changes, and modulates the processing of social information in adults. Yet little is known about children and preverbal infants' responses to first-person experiences of ostracism. The current study aimed to explore the efficacy of a triadic ball-tossing game in manipulating social inclusion and ostracism with 13-month-old infants (N = 84; 44% males; mostly White; tested from 2019 to 2022) by developing an observational coding system.

Ostracism modulates children's recognition of emotional facial expressions.

Ostracism has been shown to induce considerable physiological, behavioral and cognitive changes in adults. Previous research demonstrated its effects on children's cognitive and behavioral abilities, but less is known about its impact on their capacity to recognize subtle variations in social cues. The present study aimed at investigating whether social manipulations of inclusion and ostracism modulate emotion recognition abilities in children, and whether this modulation varies across childhood.

Sequential learning of emotional faces is statistical at 12 months of age.

Infants are capable of extracting statistical regularities from continuous streams of elements, which helps them structuring their surrounding environment. The current study examines 12-month-olds' capacity to extract statistical information from a sequence of emotional faces. Using a familiarization procedure, infants were presented with videos of two actresses expressing the same facial emotion, and subsequently turning toward or away from each other.
