8. 3/6/2016Computer-Mediated Communication — Cheshire & Fiore7 Using ‘Games’ to Understand Trust- Building

9. 3/6/2016Computer-Mediated Communication — Cheshire & Fiore8 Rules for the CMC trust game…  Two players  Each player gets 10 items (X’s) from the experimenter on each round.  Players simultaneously decide whether to ‘entrust’ 0 to 10 of their items to the other player.  Players decide whether to return the items to the partner or not.  If player returns the items, the experimenter DOUBLES the amount returned to the partner.  The player can just keep the entrusted items; then nothing is returned to the partner.

10. For Example… 3/6/2016Computer-Mediated Communication — Cheshire & Fiore9 Player A entrusts 1 X’s Player B entrusts 3 X’s Player APlayer B Player A returns the 3 X; Player B gets 6X! Player B returns the 1 X; Player A gets 2X! At the end of the round, you keep whatever you did not entrust, plus whatever you earned or kept from your partner!!

Does the game play any differently when there are repeated interactions with the same partner, compared to when there are new, random partners?
