American Sign Language can improve IQ, cognition, communication skills, frustration, vocabulary, confidence, reading level, learning abilities, and understanding in babies and children. Signing is also beneficial for those with conditions like apraxia, autism, cerebral palsy, and Down syndrome. Signing allows for communication with those we previously thought we couldn't understand. Approximately 1.2 million Americans use American Sign Language, representing 0.49% of the total US population.
