Even though more than 20% of people with autism have little or no language, research into ways to help this group have really been lacking.  Several efforts to not just understand the abilities and disabilities of this group started a few years ago and we are just starting to hear about what works and what doesn’t work to improve communication in those with little or no language.  This podcast summarizes the evidence, which points to combinations of things, rather than things in isolation, and peeks in on ways in which interventions can be better directed and made more effective.
