Practically speaking, what is the difference between someone who is nonverbal and someone with autism spectrum disorder who is selectively mute?
non verbal is a term that is traditionaly & medicaly associated with the non verbalism of severe/profound autism; that is through lack of speech [whether cognitively, no language,oral motor failiure etc] with selective mutism [think its called elective now?

] people have the normal ability to speak but through specific situations theyre stopped from speaking;its a phobic/ fear response, a example of this is the guy on 'big bang theory' who can only speak to women when drunk,as elective mutism is strongly associated with social anxiety.
some fully verbal very introverted autists choose to not speak as its more comfortable for them,under medical/traditional defining they woud be neither elective mutist or non verbal autistic, they woud be defined under general mutism.
