Mason has never done this (turning his back and talking), but I too, think it's a way for him to communicate without having to worry about eye contact. It makes it a little more tolerable for him. Mason just usually doesn't respond, so I don't know if it's okay to let Hayden do this, but at least you are getting some sort of response from him. See if other's think it's okay to allow him to do this, or if it's better to try and stop this behavior.
Mason too, does scripting...usually when he is upset he will just burst out into a movie or commercial or when he is overly excited....so I guess he is scripting quite a bit!! His scripting is never in context. Just random quotes from anything he has heard...he sticks a lot to his favorites, but then there are a lot that I have no idea what they are from too.
My ds's eye contact at home is okay (not great) but when he is in a new orEye contact is difficult for kids with autism -- it gives a lot of visual stimulation that makes it harder to concentrate on what's being said. Turning his back sounds like a coping mechanism. Stress or excitement would make it that much harder for him to process what's being said.
Of course, it's not polite and in the long-term you want to teach him to give some eye contact or at least face his conversation partner. A social story and visual cues might help.
The thing about saying irrelevant things could be an attempt to change the subject to his special interest, in which case you can teach him what to say to appropriately change the subject. However, it could be "scripting" -- trying to communicate with a phrase he's learned. The problem is, we don't know the context in which he has heard "okay, oh no t-rex," so we don't know what it means (if indeed he heard it on a dinosaur movie or something).
Here's an example of scripting: My son once used "I don't want to live anymore" to communicate his desire to escape from an intolerable sensory-situation, not understanding that the phrase actually means a death-wish. He had picked it up from a movie or something, made assumptions about what it meant and used it to communicate based on those assumptions.
Good luck with everything.
I had a question. I noticed that my son does something strange sometimes. Sometimes when someones talking to him he turns around and gives that person his back and talks to them then like he dosnt want to see them. Hell also throw something totally off topic in there too. He dosnt do it all the time but I noticed he does it alot when hes anxious or really excited. like heres an ex.
We were at an imaging center for an MRI he had to get and the doctor came out and started asking him if hell drink some juice he have for him. My son started hyperventilating alittle and saying he dosnt want a needle shot. The doctor said he wont give him a needle shot he just has to drink the juice for him and would he do that please? Hayden turned around and faced his back to the doctor and said ok. The doc asked for a high five which he turned around to give a fast one then faced his back again. Then hayden went back to the needle shot and he dosnt want it. The doc said hes not giving him one. Hayden started smiling and laughing and rubbing his eyes, then said really upset "i dont want a needle shot" The doc repeated himself and said if he takes the juice he wont need a needle shot. Then hayden starts laughing and says ok, o no t-rex!. He dosnt look at the doctor all this time and only turns around when hes leaving.
Other times someones talking to him, nothing stressful, and he happily turns around and starts talking to them backwards and if the person tries to touch his hand or turn him around hell get upset. Or somethimes hell just run off and turn into an imaginary character.
Does anyones kids do that? Is it stress related or overstimulation? If so what could you do to stop him from doing that when he does?
