In file game/game.settings.js 6 treatments are available:
-
rank_same: corresponds to condition "Flat" of Paper 1.
-
rank_skew: corresponds to condition "Tiered" of Paper 1.
-
threshold_random_com: corresponds to condition "Com" of Paper 2.
-
threshold_random_coo: corresponds to condition "non-Com" of Paper 2.
-
threshold_select_com: corresponds to condition "Com" with non-random review selection of Paper 2 (see Appendix).
-
threshold_select_coo: corresponds to condition "non-Com" with non-random review selection of Paper 2 (see Appendix).
Current codebase is ported to the latest version of nodeGame from previous versions. It is not the exact code used in either paper. In particular, a notable difference from paper 2 is that creation and submission are in two separate steps, instead of in the same step with a popup window. Moreover, in paper 2 there was no pre-game survey, only a small demographics survey at the end of the experiment. Finally, actual payoff values are different.
