Hey, I had a look at the survey but I'm a bit unsure of what you want to know as the questions are a bit general. What sort if images are we talking about? Photos, cartoons, TV images, all of these, none of these?
In all honesty, I find this survey a bit bewildering: some of the questions seem to require a full-on philosophical response whereas others appear so simplistic and obvious that they barely require a response at all.
Have you tried to complete it yourself? If so, it'd be interesting to see your sample response; if not, I recommend you give it a go.
'Why do you think images exist?' is the kind of question I'd generally expect to come with a few weeks' notice and a 2,000 word limit rather than as Q1 in a two-minute survey... I think the feedback on this thread (my own included) kind of suggests that the questions would benefit from a bit more work.
If I were allocating two minutes to this, my answers would be as follows:
1. Because eyes exist
2. Because they stimulate my visual cortex
3. I like it when they look good
4. It depends
5. It depends
6. Everything in the apparently random list above and more
