I took your test. It was very interesting. How long are you going to conduct it before compiling results?

Thank you

I have to report my results on April, 25th and hand in my thesis on May, 3rd so I think I'll start the statistical analysis in about four weeks.

I can not take your survey as there's still no option for a large part of the autism spectrum, namely PDD-NOS. I won't choose "Other psychological condition or disorder" as probably it serves a different purpose.

I feel left out - again.

Sorry.

Took the test. Intriguing hypothesis, keep us posted!

OJani:
Yes I noticed, and I'm sorry for that. Somehow my instructions to update the diagnoses question didn't fully go through.
If I update it again I'd have to clear my collected data again which could corrupt the analysis later on if I have to puzzle everything together from multiple data sets.

I'd be happy if you selected "other psychological condition" or whichever you feel matches your diagnosis most closely.

I, of course, did not intent to leave out or discriminate against any kind of psychological condition.

No, they will not be affected by this because the demographic data is just to get an impression of the sample population.

The statistical analysis will be performed from the questionnaire results and the test results. My hypothesis is not based on gender/age/diagnoses/nationality, etc.
Just for the reaction time, it might be necessary to correct for age, but I'll see that when I get the full set.
I might also add that non-native speakers of English might interpret the questions differently - but then, everyone does to an extent.

That is why my hypothesis isn't based on whether the person is defined as being on the autism spectrum or not but on the extent of their displaying behaviour and characteristic typical for those on the autism spectrum.
You don't need to be diagnosed with anything to participate and it is a correlational design not a grouped design. Hence, the replies to the demographic questions will be included in the participant description of the study - for which they are necessary - but not in the statistical analysis.
I could have designed my study so it requires the categorising into diagnosed and undiagnosed participants but I didn't. The experimental design to test a hypothesis is really mainly governed by the available means and preference of the researcher. My means are very limited, and I chose this as the best design, given my resources.

I don't understand the relation to the existence of diagnoses in general.

Just finished taking the survey, had no problems with it using Firefox.

I was pretty well into this test and then change my mind because I became irritated with the repeated questions. No wonder this thing takes so long.

Thank you to all those who participated in my study!

The analysis showed a significant correlation between detail-oriented visual processing preferences and the expression of character traits and behaviour typically associated with autism spectrum disorders (p = .003, N = 87 for the Embedded Figures Test measuring field independence in visual processing; p = .016, N = 87 for the Hierarchical Association Test measuring preference for global or local association in visual stimuli)
Further regression analysis showed that reaction time in the Embedded Figures Test and preference in the Hierarchical Association Test can be predicted with reasonable accuracy from the scores in the ASD questionnaires(pEFT = .006, B = -2.01; pHAT = .032, B = 0.001)

Of the 87 participants completing the whole experiment, 43 entered their e-mail address to take part in the voucher raffle.
I put the addresses in a random order, generated a random number (both at www.random.org) and counted from the top down (starting at the beginning again when the number was higher than 43) to determine the winner for the £10 and £20 vouchers
.
The winner for the £10 voucher is fos***@***.com who chose Amazon.com

The winner for the £20 voucher is muk***@***.com who chose Amazon.co.uk

They will both be notified by e-mail shortly.

Furthermore, I was awarded a prize at the project poster presentation of this year's graduates and I want to thank the participants again with this in mind, as it would, obviously, not have been possible to present good results without people willing to go through all 145 questions.
So, thank you~

PS. Concerning the possible confounding factor that the participants might choose to reply what they think is the "right" answer, instead of what they really think: social desirability is, of course an issue in all questionnaire and interview type psychological measures. There are often "lie scales" implemented in questionnaires to identify the extent of an individual's tendency to choose socially desirable replies and high scores will render the complete result unusable.
However, my study is a simple final year undergraduate project so I had neither the resources nor the time to generate "lie-resistant" tools, or had the liberty of excluding many of my participants as the total number was only 86 - which is hardly representative.
