So a couple days ago, I was talking to a friend (my only friend, who also know about my Asperger's) on the phone, and I was about to go into a store to buy some stuff I needed, so I just told him that I would call him back afterwards. He became confused and asked why I couldn't continue to talk AND buy my stuff. At first I was not sure how to answer, to be honest I didn't know. But just the thought of doing it seemed uncomfortable, and it made me want to hang up the phone while I was in the store.
I told him that if I tried it would take me a very long time to buy the stuff even though I knew exactly what I needed, because I would be focusing on the conversation and meanwhile wandering aimlessly in the store, and that it would probably be hard to hear him in there anyway. He was still not convinced, and I eventually came to the conclusion that maybe it was because what he was asking me to do was to multitask, which I have a very hard time with. When I said this, however, he was thinking that maybe I was just limiting myself by thinking such things and that I should try it, not understanding how stressed out I can get from it. He was using examples like, "Can you walk and talk?", just simple things like that which I don't consider multitasking. It wasn't the walking part that was the problem, it was that I'd be going in the store, with all the talking and beeping and crying babies, attempting to find items I didn't know the location of, and simultaneously trying to listen, understand, interpret and respond to the things he was saying. I suppose I CAN do it, but not efficiently, and it would stress me out.
Finally the way I managed to get him to understand was to tell him to imagine that everyone's mind is a computer. Most people are able to run maybe 2 or 3 larger applications at once on their computer. They can do this because they have the processing power to do so, AND they can end unnecessary tasks to free up their CPU. For me, however, I can't shut down those unnecessary background tasks. Therefore, if I try to run too many big programs, even in the background, the computer slows down, freezes, and may even need to shut down and restart to start working again.
That is an accurate description of why I can't do it. I typically avoid multitasking with phone calls especially, unless I have nothing I am doing, because for some reason it is really difficult for me to do anything else while talking on the phone. But I was wondering, is this the same for most Aspies? To be honest I don't think there is true multitasking, because that would imply concentrating on two or more things equally, when really it seems to me that some people are just good at being able to do certain things without really thinking about them and can do them subconsciously while focusing on just one other thing. That, and I also believe that their mind is going faster, switching back and forth between tasks so quickly and easily that it seems simultaneous, but it's not.
I could be wrong though. Any thoughts?
