Increased effort requirements and risk sensitivity: a comparison of delay and magnitude manipulations

Reward magnitude and delay to reward were independently manipulated in two separate experiments examining risk-sensitive choice in rats. A dual-running wheel apparatus was used and the tangential force resistance required to displace both wheels was low (50 g) for half of the subjects, and high (120...
