For my research topic I will be examining if it is possible to walk in a straight line while blindfolded. Experiments have shown that it is not possible to walk in a straight line without a visual landmark. However, I plan on using first hand study and research to see if different sounds will help to keep people on a straight path.
This video and article provides a clear description of the problem that people can not walk in a straight line when they have no visual landmarks to work off of. It gives specific examples of people who have tried this experiment and what the results were.
I will be using this to to establish what others have done to test this problem. I will also be using it to help guide me through my own personal research.
In this video The Mythbusters, Jamie in particular, offer up a theory that we cant walk in a straight line because the body makes fluid movements and is not perfect. Eventually, all of the little errors that are made while walking, without correction, will pile up causing us to walk in circles.
I will use this as a possible answer to the mystery question of if there is any way for us to actually stay on a straight path without the help of visual landmarks. I also noticed in the video that while doing the experiment they were wearing noise cancelling headphones, so that still leaves my theory that noise can substitute as a landmark open.
This article gives more information about Jan Souman’s experiment where she blindfolded participants and let them attempt to walk straight in the desert or through an open plain. There is also a video about her experiment.
I will use this to help me determine how large of an area I should use to conduct my own experiments. Unfortunately, I will not be able to use an area as large as in the original experiments.
Gives all of the information about the experiments where she had subjects walk through the woods on a cloudy day as opposed to blindfolding them. Also gives more information about all of the separate tests since this is her main research paper.
I will use this as my main source in my research paper, getting most of my information about her theories and experiments from it.
5. Personal experiment
I will do my own experiment to see if we can walk in a straight line while blindfolded. I will also attempt to find out if noise can be used as a stand in for a visual landmark.
