Abstract
A long (150-trial) PD game, played for money, was used to study the developmental effects of motive constellations and first-trial outcome on coopera tion-conflict behavior. Game partners were matched for their dominance in the TAT-measured needs for achievement, affiliation, or power. Results were: (a) the motive groups developed considerably different levels of cooperation-conflict by the end of the games; (b) some motive groups did not behave as hypothesized; (c) first-trial outcomes affected subsequent behavior, but the effects "washed out" by the end of the games. The discussion emphasized the appropriateness of the systems model for understanding personality and situational effects in social interaction.
