One theory of the autistic brain is that it is a "specialised" brain in that there are less connections between the main brain centres hence making multitasking extremely difficult for us. We work better focusing on one thing at a time compared with NTs.
This gives rise to one explanation of why socialising is so difficult for us as socialising involves a LOT of multitasking - tones of voice, words, meaning, facial expressions, body language, trying to understand any hidden meanings, then trying to think our own thoughts and control our own tone of voice, body language, facial expression, focal points, as well as filter all sensory input such as noise, sights, temperature, balance, etc... It results in us missing a LOT of information being put out and hence we make many social mistakes. Then introduce another person into the conversation, and another, and it all just falls apart!
