Consent Form to Participate in Scientific Research

We would like to invite you to participate in a web-based online experiment. The experiment is part of a research study whose purpose is to study how groups perform decisions.

You must be at least 18 years old to participate.

The decision to participate in this research project is voluntary. You do not have to participate and you can refuse to answer any question. Even if you begin the web-based experiments, you can stop at any time by closing your browser.

There are no foreseeable risks or discomforts to you for taking part in this study. We anticipate that it will take about from 8 to 25 minutes to complete this task. However, you will only be rewarded for completing the task, not for the length of time you participate.

You will be compensated for good faith participation in this experiment. Submitted HITs will be rejected if they are completed in a manner that appears to be random, incomplete, or otherwise negligent.

Your part in this study is anonymized to the researchers. Researchers at the Army Research Office and Office of Naval Research may have access to anonymized experimental research records. However, because of the nature of electronic systems, it is possible that respondents could be identified by some electronic record associated with the response. Neither the researcher nor anyone involved with this study will be capturing those data. Any reports or publications based on this research will use only group data and will not identify you or any individual as being affiliated with this project. The only individually-identifying data we receive from Mechanical Turk are your unique identifier and your country. Your data are also stored on Mechanical Turk's servers, and the data there are subject to the Amazon Mechanical Turk Privacy Notice and Participation Agreement.

If you have any questions regarding electronic privacy, please feel free to contact Mark Nardone, NU’s Director of Information Security via phone at 617-373-7901, or via email at privacy@neu.edu.
