Here's a great survey that will take about 10 minutes to complete. It's open to anyone and they've done a great job of being inclusive. Heads up - don't get critical while taking it - the study has great motives and it's an interesting study that I think you'll enjoy - so just go with it :)

Details from the researchers:
Purpose of Study: In the first study, we are looking at the effects of visual imagery on memory and recall. Does “seeing” a news story help us remember it better than reading a news story? In the second study we are looking at the categorization of visual images. How fast can you put pictures into groups?
Description of the Study: These studies will take approximately 20 minutes to complete online. For the first study, you will be watching a slideshow of images summarizing a recent news story and you will be asked to recall that information. For the second study, you will be asked to look at visual images and categorize them into different groups. You must be 18 years of age or older to participate in this study.
