We've reported here before on the research of Dennis Proffitt on the perception of distance -- how wearing a backpack can cause you to perceive distances as longer. Now the team has a new study, which is featured today in seedmagazine.com. In this study, they examine the perception of the steepness of a hill:
To test his hypothesis, Proffitt asked participants to estimate the slant of a hill on the UVA campus, while outfitting some of the subjects with a heavy backpack. They found that subjects donning backpacks estimated the slant to be much steeper than did those who had nothing on their backs.

I'm usually disappointed when I try to take a picture of a steep precipice—it never seems as impressive in the photo as it did when I was standing right there. Take this photo, for example. It's a nice shot of my daughter Nora, taken on our hike in the Great Smoky Mountains this past summer, but…
ATHLETES who are on a winning streak often claim that they perceive their targets to be bigger than they actually are. After a run of birdies, for example, golfers sometimes say that the cup appeared to be the size of a bucket, and baseball players who have a hit a few home runs say that the ball…
WE tend to assume that we see our surroundings as they really are, and that our perception of reality is accurate. In fact, what we perceive is merely a neural representation of the world, the brain's best guess of its environment, based on a very limited amount of available information. This is…

Thank you for this great lead.
I have Information Visualization blog [ http://akbani.blogspot.com ]. Till now I was wondering which category this type of knowledge would fit in. Now, would consider including me into your fraternity, and link this blog?
Keep up the good work.

Some recent posts at my blog, f.y.i.:
As an ex-soldier, I can attest that this is a trainable behavior. New arrivals to a tactical unit were expected to be lousy at estimated distance, so many units routinely take them into the field in heavy packs and purposely teach them how to pace of a distance with and without a backpack and do exercises such as firing markers with and without gear, on slopes, etc. Maps and compasses are used for navigation course to teach you to estimate distance accurately. After 2-3 of these exercises, virtually all soldiers were much more accurate at estimating distance, relative altitude, etc.
