In Research to Support the General Aggression Model, Sheese

In research to support the general aggression model, Sheese & Graziano (2005) had college students play either a violent or non-violent version of the video game Doom. They then participated in a prisoner's dilemma game that requires the participant to either cooperate or compete with another person. The researchers' findings indicated

A) those who played the violent version of Doom were more likely to compete in the subsequent game.
B) those who played the non-violent version of Doom were more likely to compete in the subsequent game.
C) only those participants who played the game in aversive conditions were found to compete in the subsequent game.
D) all of the participants were more likely to compete after playing either version of Doom.
