The purpose of this experiment is to investigate the relationship between visual attention and perception to better understand the biological mechanisms of behavior, and to develop engineering applications. We expect that about 7000 people will participate in this study.
You will be asked to look at your computer screen and press the buttons of your mouse in response to what you see, much in the same way as playing a video game. The experiment will take about 10 minutes to complete.
There are no more risks involved in this experiment than those which might be experienced while playing a computer game. By participating in this experiment, you will provide us with important data that will help us determine how people respond to and perceive different stimuli. You will also receive first hand experience with how research is conducted by a visual psychophysics laboratory. This study may benefit society if the results lead to a better understanding of how people interact with visual scenes which may lead to better designs for computer-human interactions.
Your participation in this study is entirely voluntary: You choose whether to participate. If you decide not to participate, there are no penalties, and you will not lose any benefits to which you would otherwise be entitled. If you choose to participate in the study, you can stop your participation at any time, without any penalty or loss of benefits. If you want to withdraw from the study, simply close your Internet browser window.
No guarantees can be made regarding the security of information sent via the Internet; we cannot rule out the possibility of interception by third parties. Once we receive your data, any study records that identify you will be kept confidential to the extent possible by law. The records from your participation may be reviewed by people responsible for making sure that research is done properly, including members of the Homewood Institutional Review Board of the Johns Hopkins University, or officials from government agencies such as the National Institutes of Health or the Office for Human Research Protections. (All of these people are required to keep your identity confidential.) Otherwise, records that identify you will be available only to people working on the study, unless you give permission for other people to see the records.
You do not need to pay anything to participate in this experiment. You will not receive any payment or other compensation for your participation in this study.
