The survey obtains informed consent and will then measure how the game affects both their knowledge of recycling rules and their pro-social preferences by giving them a chance to win a $20 gift card, and the opportunity to donate part of their winnings to a curated selection of charities. Email will be optionally collected only to be able to send the winner a gift card and will otherwise be discarded. No other identifying information will be collected.
Subjects will be recruited through Amazon mTurk, online reddit forums, and during Vassar’s freshman orientation event. Since we intend to use the game during orientation, the game may be played be participants who may be under the age of 18 and may be undocumented.
Game distributed by web link either via Amazon mturk or directly to students during freshman orientation.
When students get the link to the game, they are automatically randomized into one of the five treatments, that only affects how the scoring but does not impact game play itself. No data is recorded at this stage, this also helps get past App Store approvals.
