If I want to fully interpret and understand what is written it's exactly the same for me, I have to read "aloud" in my head at the same speed that I speak.
Same here.
When I was at senior school I was also always the last one to finish reading a section from a book, often the teacher would want to move on when I still hadn't finished and it was embarrassing
Same here. It was frustrating. I used to catch up at home.
I've always been exactly the same, also while attempting to concentrate on the subtitles I miss out on the action, I therefore avoid movies that are fully subbed. At least these days we can easily wind back and pause, unless we are watching in the cinema of course and it can also be awkward if we are watching with other people who can read the subtitles easily.
Yes, exactly - I miss the action. I'm very mono-channel and can only do one thing at a time. If I read, I can't listen. If I listen, I can't read. If I speak, I can't see (I can, but I don't take in the meaning of what I see). If I'm using one of my senses, I lose the meaning of the others, I'm not able to process and interpret the input.
but I was wondering whether you had slow/delayed speech development as a young child like myself in case there's a link?
I've wondered the same thing myself. I don't actually know when I first started to speak. I was brought up by my grandparents until I was 6, and neither of them are alive to tell me, not my father, who would know. I'm sure that I was speaking by the time I got to kindergarten, though. As a small child, I was aloof and had a lot of behaviour issues and meltdowns. I was bullied a lot. Some of my behaviours, like my meltdowns and hitting a teacher, may well have got me excluded if I had been going through the school system today, but then, excuses were made for it because I had lost my mother at a young age and had been brought up by my grandparents. So I was deemed to have special circumstances. There is no record of my having had a speech delay and I was diagnosed with Asperger's, not autism, but still I might have had a slight delay or abnormal development.
The middle school thought I was very slow and wanted to move me and put me with the slow learners or a special school even, but my parents insisted that I should stay put, because they thought I was actually quite intelligent but not trying hard enough, and wouldn't reach my full potential at a special school or with the slow learners. I was bottom of the class and had terrible reports. My teachers disliked me, but I was unaware of this and how bad things actually were until recently, when I read through my old reports. In high school I did better academically, but had social issues.
