Many children with developmental disabilities are fascinated with animated TV characters. A study conducted in the UK found autistic children were far more fascinated with the characters from Thomas the Tank Engine than with other fictional characters.
Picking up on this finding, Autism Spectrum Australia (ASPECT) a non-profit that provides services to people with this development disorder has designed a Thomas The Tank Engine Emotions Game specifically aimed at autistic kids.
The game asks players to recognize which engine has a sad, happy or angry face. Each time the child plays they are presented with a different sequence of emotions. It can also be played to test a child's memory.
