Stella and Maddie are learning to play a new version of a computer game. After a couple of hours, they have both been "blown out of the water" many times. Stella comments on how slow she was to respond to the many threats the game threw at her, and how she needs to focus more on that as she practices. Maddie felt that the game moved too fast (even on the beginner setting), and that the graphics were too confusing, which threw her off her game. What might this example tell us about their personalities?
A. Maddie seems to have an external locus of control, and Stella is more internal in her approach to this game. B. Stella is blaming the number of threats and Maddie is blaming the speed and graphics of the game, which indicates an external locus of control for both of them. C. Stella realized that she needs to practice her response speed, and Maddie acknowledged she needed to work on how well she concentrated on the game, indicating that they both lean toward an internal locus of control. D. Both players are clearly in between an internal and external locus of control in explaining their performances on the game.
