The player has evolved in geological time (i.e., through Mendelian genetics) in such a manner as to promote survival and reproductive functions. The physiological behavior of the player reflects both this organization as it relates to his or her evolutionary history of dealing with biologically relevant stimuli (such as parasites and both appetitive and aversive stimuli) and the ways in which the individual player learns to adapt to potent drugs of abuse within his or her lifetime (i.e., Lamarckian evolution). The payoff matrix is determined by the player's evolutionary history, but the "choices" of behavior in response to an individual drug relate both to the player's evolutionary history and to learning processes in the lifetime of the individual. Another way of expressing this is that the payoff matrix is hard-wired, whereas the player's choices in the SPFit game are partially hard-wired but are also under the control of Pavlovian conditioning processes.
