Below is more information for the second part of the experiment:
Is this study funded?
This study is funded by NAMRU (Naval Aerospace Medical Unit).
What is this study about?
NAMRU is interested in the ability to balance in a condition similar to helicopter flight and whether visual information makes a difference.
What will you be asked to do?
You will be blindfolded and strapped into a Multi-Axis Rotation System (MARS) device. The MARS is programmed to behave like an inverted pendulum which means that if you do nothing it will fall over. An example of an inverted pendulum is balancing a pencil on your fingertip. You will use a joystick to try to stabilize yourself at the balance point. This is a difficult task and you will lose control many times.
How long will it take?
The experiment will take about 40 minutes.
Will I receive anything for participating?
You will be paid $15. This is your only compensation for participating.
Are there any possible risks to you?
This study has greater than minimal risk. This means that possible risks and discomforts are higher than you might experience in everyday life.
Can I stop after I have consented to participate?
Yes – remember, your participation is completely voluntary. You can refuse to participate or stop at any time without penalty – you will receive full compensation regardless of completing all the tasks in this experiment.
You can ignore #4 because I do not need to run a follow up experiment.
