Ah, makes sense - thanks Reenie.
My name's Rob and I'm doing a Postdoc in the south of Ireland. The experiment is part of an extension of my PhD research in HCI/interface design. This research has to do with the visual perception of interface items, hence it has a heavy neuroscientific side (although that's not really obvious from the experiment itself). All you have to do in the experiment is basically navigate a Website to find a couple of items.
I'd better not discuss it in too much detail, lest I skew people's perspectives going into it but if anyone is interested, I'd be happy to discuss it more in other threads, or by private message.
