The body and the self change markedly during adolescence, but how does bodily self-consciousness, the pre-reflexive experience of being a bodily subject, change? We addressed this issue by studying embodiment towards virtual avatars in 70 girls aged 10-17 years. We manipulated the synchrony between participants' and avatars' touch or movement, as well as the avatar visual shape or size relative to each participant's body. A weaker avatar's embodiment in case of mismatch between the body seen in virtual reality and the real body is indicative of a more robust bodily self-consciousness.

How we mentally experience our body has been studied in a variety research domains. Each of these domains focuses in its own ways on different aspects of the body, namely the neurophysiological, perceptual, affective or social components, and proposes different conceptual taxonomies. It is therefore difficult to find one's way through this vast literature and to grasp the relationships between the different dimensions of bodily experiences.

Recent studies have demonstrated that dogs synchronize their locomotor behaviour with that of their owners. The present study aims to improve our understanding of the sensorimotor processes underlying interspecific behavioural synchronization by testing the influence of the number of humans on dogs' behavioural synchronization. We used Global Positioning System (GPS) devices in an outdoor environment to measure dogs' behavioural synchronization to humans during a locomotor activity involving three speeds (static, slow walking and fast walking).

Article Synopsis
  • - The human action observation network (AON) in the brain is responsible for processing observed actions and is present from childhood, but its sensitivity to social versus object-related actions may differ between adolescents and adults.
  • - A study using fMRI scanned teenagers and adults while they watched videos of actions differing in sociality and transitivity, revealing that both groups engaged similar brain areas; however, adolescents showed lower accuracy in processing these actions.
  • - The results suggest that adolescent representation of social actions in the AON is less robust compared to adults, indicating ongoing development in how individuals understand social interactions.

Cognitive control and social perception both change during adolescence, but little is known of the interaction of these 2 processes. We aimed to characterize developmental changes in brain activity related to the influence of a social stimulus on cognitive control and more specifically on inhibitory control. Children (age 8-11,  = 19), adolescents (age 12-17,  = 20), and adults (age 24-40,  = 19) performed an antisaccade task with either faces or cars as visual stimuli, during functional magnetic resonance brain imaging.
