Do People Really Walk in Circles?
August 20, 2009
…from Scientific American…
“Yes, people do really walk in circles—but only when stripped of important visual clues, such as the sun or moon, according to a paper published online today in Current Biology.
“To test the common wisdom, Jan Souman, a research scientist at the Max Planck Institute for Biological Cybernetics, and his team sent test subjects out into a German forest and the Sahara Desert to see if they could follow directions to walk in a straight line—some on sunny days others on cloudy days or at night. Subjects were monitored via GPS over the course of hours (and followed by an experimenter for safety).”
