Developmental and postural changes in children's visual access to faces
نویسندگان
چکیده
The faces of other people are a critical information source for young children. During early development, children undergo significant postural and locomotor development, changing from lying and sitting infants to toddlers who walk independently. We used a head-mounted camera in conjunction with a face-detection system to explore the effects of these changes on children’s visual access to their caregivers’ faces during an in-lab play session. In a cross-sectional sample of 4–20 month old children, we found substantial changes in face accessibility based on age and posture. These changes may translate into changes in the accessibility of social information during language learning.

Measuring children's visual access to social information using face detection
Other people are the most important source of information in a child’s life, and one important channel for social information is faces. Faces can convey affective, linguistic, and referential information through expressions, speech, and eye-gaze. But in order for children to apprehend this information, it must be accessible. How much of the time can children actually see the faces of the people...

متن کاملPostural developments modulate children’s visual access to social information
The ability to process social information is a critical component of children’s early language and cognitive development. However, as children reach their first birthday, they begin to locomote themselves, dramatically affecting their visual access to this information. How do these postural and locomotor changes affect children’s access to the social information relevant for word-learning? Here...
متن کاملThe influence of symmetry on children's judgments of facial attractiveness.
In experiment 1, we examined developmental changes in the influence of symmetry on judgments of attractiveness by showing adults and children pairs of individual faces in which one face was transformed 75% toward perfect symmetry, while the other face was transformed by exaggerating its asymmetries by 75%. Adults and 9-year-olds, but not 5-year-olds, rated the more symmetric faces as more attra...
متن کاملSpatial and temporal postural analysis: a developmental study in healthy children.
The aim of this study was to explore further the development of postural control in healthy children. The novelty of this study was to resort to both spatial and temporal analysis of the center of pressure (CoP). Forty-six healthy children from 4 to 16 years old (mean age: 9.1±3 years) and a group of 13 healthy adults (mean age: 25±3 years) participated to this study. Postural control was teste...
