Introduction
What is social cognition?
“the ability to detect and interpret information about other individuals to adjust one’s own behaviour to the emotional and social context’’
Payne, C. (n.d.). Neuroanatomy of the developing social brain. In M. de Haan (Ed.), Handbook of Developmental Social Neuroscience (1st ed., p. 38ff). London: The Guilford Press.
Introduction
Why is social functioning important?
• well-being and success largely depends on our ability to interact with other humans
• social interaction plays a large role in motivation
• socio-emotional disorders are among the most common disorders in adults
• social interaction is important for the development of other abilities, e.g. speech and language
Introduction:
Introduction
Why study social development?
• many aspects of social function are shaped during development
• more complex behaviours build on simpler processes that can be observed in earlier stages of development
• the influence of other functions can be observed during development
Introduction
IntroductionIntroduction
Developmental social neuroscience:
• How does brain development and function relate to the development of socio-cognitive abilities and ultimately behaviours?

Internal/External Factors
Internal/External Factors
Internal factors
• visual ability
→ individuals that had no visual input to the right hemisphere during infancy perform sign. worse on the spacing task, which requires configural processing
Le Grand, R., Mondloch, C. J., Maurer, D., & Brent, H. P. (2003). Expert face processing requires visual input to the right hemisphere during infancy. Nature neuroscience, 6(10), 1108–1112. doi:10.1038/nn1121
Internal/External Factors
Internal factors
• visual ability • genetic predisposition
Intraclass correlation compared between monozygotic and dizygotic twins
→ the shared variability on face-specific tasks is higher in monozygotic compared to dizygotic twins

External factors
Internal/External Factors
• environmental influence
→ infants’ own-race bias depends on exposure in their environment

neuroscience, 10(4), 512–522. doi:10.1038/nn1865
→ responses of areas in the core face network become more selective for face stimuli with age !→ behavioural performance in a face recognition memory task also increases with age
Brain Development
Development between childhood and adulthood
➡ no face-selective activation in children, object-selective and navigation-selective activation similar
➡ face-selective activation in the core face network is similar in adolescents and adults

• faces are an important source of information for infants
• attention to faces is linked to important developmental outcomes in infants
• joint-referencing and shared gaze rely on communication with the caregiver through facial cues
• developmental disorders, e.g. autism spectrum disorder, show alterations in these behaviours
Communication
Communication difficulties
• Möbius syndrome: congenital facial paralysis

→ the ability to produce facial expressions influences social competence
Communication
Communication difficulties
• the ability to communicate facial expressions also influences the ability to decode facial expressions

Socio-emotional
ASD intervention study
• children with ASD are brought to look at faces by pairing the faces with stimuli that they intrinsically like, e.g. trains, clocks etc.
➡ their emotional vocabulary and situation-expression matching ability improves significantly

Levels of observation
• different levels of observation interact Internal/external factors interact with brain development. This leads to behaviours that subsequently influence the further development of the systems
• example: internal factors (genetic/epigenetic) lead to biases in attention in ASD (sticky attention). These could lead to differences in face processing that could lead to differences in social function.
➡investigations of neurodevelopmental disorders need to take different levels in to account

neuroscience, 1, 7–21. doi:10.1016/j.dcn.2010.07.003
Neuro-cognitive Development
• response characteristics develop from broadly tuned to highly specific Infants ERP response at 3-months does not distinguish upright and inverted faces, at 6 months there is a specific response to upright faces
• cortical mechanisms develop later than subcortical mechanisms → functions that are mediated by cortical networks might (in part) be mediated by subcortical structures in infants
• different structures develop at different rates e.g. the sensorimotor cortex matures earlier in development than prefrontal cortex
• cortical networks for specific functions mature between childhood and adulthood e.g. face processing networks show closer integration between cortical areas in adults compared to school age children
