Survivors of pediatric medulloblastoma (MB) are at-risk for neurocognitive and social deficits, including specific skills such as facial affect recognition which is the ability to recognize the emotional expressions of another person. Because the underlying mechanisms of these deficits are poorly understood, the investigators propose to examine social-cognitive skills (i.e. facial affect recognition) and indices of brain integrity, including an established core neural network of face perception in MB survivors and healthy controls. By comparing these outcomes between survivors of MB and healthy controls, investigators seek to identify the areas of the brain that help individuals recognize emotions.
