I have developed a software package that I refer to as "EMOTLAB." EMOTLAB software generates a computer interface in which the user can play any one of 78 distinct two-person, two-choice economic bargaining games (e.g., prisoner's dilemma, coordination game) with a virtual opponent who is visible on the screen during each round of play (see Figure 1).

The virtual opponent appears on screen at the end of each round of play as a digital image (e.g., jpeg or video) depicting any one of six different emotions (see Figure 2 below).

EMOTLAB software also enables the experimenter to make the virtual player's behavior contingent upon the user's behavior. For example, the virtual partner can be programmed to defect whenever the user defects (e.g., Tit-for-Tat). Finally, the emotional display of the virtual opponent can be made contingent upon the user's behavior. For example, the virtual partner can be programmed to display anger whenever the user defects and happiness whenever the user cooperates (or visa versa).
