Developmental Social Cognitive Neuroscience: Insights From Deafness

The condition of deafness presents a developmental context that provides insight into the biological, cultural, and linguistic factors underlying the development of neural systems that impact social cognition. Studies of visual attention, behavioral regulation, language development, and face and human action perception are discussed. Visually based culture and language provides deaf children with affordances that promote resiliency and optimization in their development of visual engagement, executive functions, and theory of mind. These experiences promote neural adaptations permitting nuanced perception of classes of linguistic and emotional-social behaviors. Studies of deafness provide examples of how interactions and contributions of biological predispositions and genetic phenotypes with environmental and cultural factors including childhood experiences and actions of caregivers shape developmental trajectories (M. I. Posner & M. K. Rothbart, 2007).
