not sure whether everyone knows about this, but thought it might be useful...
the uk autism society suggested i take this test. normal people core about 16/50- anything over 32 is considered 'on the scale'.
HOWEVER- i do advise taking it several times, over several days.
it actually presupposes a high degree of self knowledge and self honesty, and some of the questions are- for me- ambivilant, or useless- eg- you can easily remember phone numbers? i NEVER have to as they are all in my phone. so i dont know. and other questions about numeracy- im PREFOUNDLY dyscalculate, and slightly dyslexic, so no- i dont get obsessed with numbers, as i cant read them properly in the first place. but a higher than normal percent of people with asperger's have dyscalculia, i read... and also- i dont have any weird collections or obsess over learning about something- but im constantly being told that having about 5-6,000 books is abnormal. but- i like reading, i have the space (sort of)- why not?
and there is NOTHING about hyper sensativity to senses, or synesthesia etc.
i did find it helpful, for all that, and was really surprised i scored over 32 (since i thought the quetions were rubbish)!
