Affect in the dark: Navigating the complex landscape of social cognition in blindness

Research on the consequence of blindness has primarily focused on how visual experience influences basic sensory abilities, mainly overlooking the intricate world of social cognition. However, social cognition abilities are crucial as they enable individuals to navigate complex interactions, understand others' perspectives, regulate emotions, and establish meaningful connections, all essential for successful adaptation and integration into society. Emotional and social signals are frequently conveyed through nonverbal visual cues, and understanding the foundational role vision plays in shaping everyday affective experiences is fundamental. Here, we aim to summarize existing research on social cognition in individuals with blindness. By doing so, we strive to offer a comprehensive overview of social processing in sensory deprivation while pinpointing areas that are still largely unexplored. By identifying gaps in current knowledge, this review paves the way for future investigations to reveal how visual experience shapes the development of emotional and social cognition in the mind and the brain.
