Participants make more acquisitions on trials where the mean EV of the two gambles is low, and when the two EVs are similar (higher difficulty). The presence of a large risk difference reduces the difficulty effect (interaction p < 0.05). High mean risk increases the difficulty effect when mean EVs are low, but decreases it when mean EVs are high (interaction p < 0.05).
