Recent technological communication intervention advances have contributed to the evidence base in Rett syndrome. Method: The Embase, PsycINFO and MEDLINE were systematically searched for peer-reviewed…

This paper provides an overview of the literature investigating the functional relationship between the use of the Picture Exchange Communication System (PECS) and maladaptive behavior (i.e., aggression, tantrums) in individuals with autism spectrum disorders (ASD). Digital searches were conducted to identify single subject design studies…
