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.

Yet, sleep is known to be essential for brain maturation and a key factor for good academic performance, and thus is particularly critical during childhood and adolescence. Although previous studies reported associations between screen time and sleep impairment, their causal relationship in adolescents remains unclear.
