One of the things picked up at DS's assessment, which resulted in an ASD/aspergers DX, was that he struggled to recognise emotions when shown pictures of faces. He could identify 'happy' but muddled 'sad/angry' and when pushed by the SALT to tell her how the picture faces were feeling, he just told her he couldn't know how they were feeling because they were not in our world.
The outreach worker who has subsequently observed him in school has picked up on that part of his assessment report, and recommended a DVD called The Transporters Promote Emotions which is geared to ASD children aged 2-8, emphasis on watching 15 minutes daily for 4 weeks. According to the bumph I've been given, "A new study to be published in the Journal of Autism and Developmental Disorders from Cambridge University has found that after watching the DCD for just 15 minutes a day for four weeks, most children with autism caught up with other children in their ability to recognise emotions".
I am a bit cynical about this to be honest...I mean, can it really be that simple
But I would be interested to hear whether anyone has used it with their child and if so what you thought of it.
