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.

Abstracts
Visual attraction pervades our daily lives. It influences and guides our moods, behaviours, and decisions. Scientists apply psychological and cognitive neuroscientific methods to disentangle the seemingly complex attractiveness evaluation, and the rigorous scientific findings are growing quickly. Facial attractiveness has been a central interest in the science of attraction. In this symposium, we present new insights on attractiveness judgments with a focus on face perception from a wide range of methods including behavioural testing, computational modelling, neuroimaging, and brain-stimulation. We anticipate that it will engage interests of the APCV attendance and that it will draw a large and lively audience.
Firstly, we show a data-driven mathematical modelling which reveals physical features of a face contributing to attractiveness judgments (Nakamura). We, then, present a study which visualises a 'mental template' of attractive faces by applying the reverse correlation technique and deep convolutional neural network (Naito). The first two talks can elucidate physical and measurable features of attractive faces and what contributes to the judgment. Secondly, we show how facial attractiveness judgment can be formed. We present evidence that attractiveness judgment is a dynamic process in which each facial feature (e.g. eyes, nose, hairstyle) is integrated over time to construct a final evaluation (Saegusa). Next, we discuss the brain systems, that are possibly underlying in attractiveness judgment on faces and compare them with non-facial/non-biological stimuli in relation to cortical-subcortical networks (Ishizu). Finally, we demonstrate the 'causal role' of those brain sites when judging attractiveness of faces and other visual stimuli with the application of non-invasive brain-stimulation techniques (Cattaneo). Understanding attractiveness evaluations and the impact of visual experiences is an indispensable part of understanding human interaction with the visual world. This symposium, showcasing diverse methods to approach the question, will provide new insights into the studies on attraction and attractiveness.
