I was pondering this today. My ds is 100% non-verbal and shows zero likelihood of ever developing speech. It doesn't seem to worry him! Instead, he communicates by taking people to where he wants to go, by using a few basic photo cards (when promted, rarely spontaneously) and via his body language (to include whingeing, stomping about, yelling, etc). He understands some language, for example, those words/sentences that he has heard countless times over the years and which apply directly to the situation at hand. I think he picks up on certain nouns to cue him in.
So...given a child such as my ds, just how does he think because I seem to think using words! Are my ds's thoughts likely to be a series of images, film-reel style?
My ds clearly calculates things 'on the hoof', for example, if he sees an opportunity (e.g. an exposed tap just begging to be turned on), then he will quickly check over his shoulder to see how likely it is that his fun will be interrupted or hindered in some way, then he will make a swift and determined dash towards the desired object.
He also thinks/plans mischief things in a more leisurely manner too. Then, when he thinks I'm napping, he will seize his moment.
Any theories about what is going through his head???
