Symposium Abstracts:

Human possess remarkable capacities to process face- and body-related signals. Prior studies consistently reported visual sensitivities to face and body at birth (e.g., Filippetti et al., 2013; Johnson et al., 1991). Moreover, culture specific experience shapes the development of the visual system to develop expertise for specific types of faces and bodies (e.g., own-race faces and communicative body gestures). Furthermore, it is well known that the development of face and body perception is at the foundation of more complex perceptual and cognitive abilities, such as learning and social skills. In this symposium, we will present 5 talks focusing on the early development of face and body perception from infancy to childhood by using a broad range of research methods: skin conductance, electroencephalogram (EEG), eye-tracking, and psychophysics measurements.

Xiao will show how experience of face-race determines early development of infants’ social perception, social learning, and stereotype formation. Chien will show that the pervasive own-race face experience shapes the development of fine-grained and efficient face perception across childhood, which further links to biased social development in childhood. Nava examines the development of multisensory integration from early infancy to childhood and its contribution to the development of body representation. Yang will show tactile information facilitates visual processing in infants, and how body representation modulates this multisensory enhancement. Hirai will talk about infants’ perception of body movements and bodily gestures, and its role in social learning.

In sum, this symposium brings together the latest findings regarding face and body perception across various stages of life and in different culture settings. These studies shed insights into the current advances and future directions of the field of early development of face and body perception.
