Bruce, Susan M.; Zatta, Mary C.; Gavin, Mary; Stelzer, Sharon – Journal of Visual Impairment & Blindness, 2016
Introduction: Deafblindness limits access to social cues and social feedback, thus restricting the development of social skills. Many children with CHARGE syndrome, a leading cause of deafblindness, experience challenges with emotional self-regulation and anxiety that may interfere with socialization. Learning about self-determination skills such…
