This survey is open to anyone who speaks English and is 18 or over. It takes around 10-15 minutes and involves visiting another website (URL and instructions included) for a 3 minute test. This survey is easiest to complete on a laptop or dekstop computer rather than mobile. Link

Edit: Thanks for the comments that the external site is difficult to use, I only tested this on a desktop computer and laptop so I didn't realise this was an issue with loading/getting back to the questionnaire, plus a few comments about questions that would have been useful to include. This is some background research for my university dissertation. The sample for my real dissertation are children, but I wanted to look into the patterns of this in an adult sample. I recognise the intelligence measures in this aren't great, as I'm only using freely available resources and wanted to keep this short, so the results of this won't be particularly high quality/scientific. It'll be interesting to see if there are any patterns in the data collected from this and once I've got enough participants and had a look at the data I'll post about the results. Thanks to everyone who took the time to complete it.
