Title of Project: Behavioral Experiments over Amazon Mechanical Turk

We would like to invite you to participate in a web-based online experiment. The experiment is part of a research study to investigate problem-solving. A single experimental session should take no more than 5 minutes to complete.

You must be at least 18 years old to participate in these experiments.

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 you as little as 2 minutes and as many as 10 minutes to complete this task. You will only be rewarded if you complete the entire task.

Your 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 participation in this study is anonymized to the researchers. Neither the researcher nor anyone involved with this study will be capturing data that can identify you as an individual. 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.
