How non-verbal communication differs from visual communication?
Non-verbal communication disorder is when a person does not have expressive speech. The person has an oral disorder that prevents letters from combining sounds and creating speech. Visual communication is a teaching tool to help non-verbal persons improve their communication using pictures. PECS, Picture Exchange Communication System, is a visual communication tool. PECS and other visual communication tools assist non-verbal students in social interaction, education performance and behavior. These visual communicaton tools are helpful for students who have autism, asperger’s syndrome, down syndrome, communication disorder, language delay, hearing impairment, aphasia and many more.
