In 2 experiments 70 male and female and 89 female undergraduates were required to observe and predict the behavior of a hypothetical "chooser" who made choices for him- or herself and for a hypothetical other in a series of decomposed games. The preference for outcomes, or social motivational orientation, of the chooser was preprogramed and varied across conditions. Ss were more readily able to detect the outcome preferences of choosers who made choices according to individualistic or competitive choice rules than of choosers who behaved in a prosocial or negatively self-interested manner. Furthermore, the prediction data from Exp II reveal that Ss tended to perceive choosers' own gain as an important component of most of the choosers' secondary motivation. Evidence from Ss' ratings of the choosers' personality attributes and estimates of the relative weights the choosers attached to their own and the other's gain (Exp II) indicated that Ss formed distinctive impressions of the choosers despite differences in predictive accuracy across conditions. Exp III with 64 undergraduates was performed to investigate the relationship between predictive accuracy and the mathematical complexity of the choosers' various choice rules; no evidence was found that mathematical complexity influenced Ss' performance on the prediction task.
