Keanan Joyner - Alternative Rewards and Multiple Methods

Some research demonstrates that rats will self-administer dangerously high levels of drugs under certain schedules of reinforcement. However, much of this research has been done under conditions of depravity, in which the rat does not have any access to alternatives. Humans almost always make choices between a menu of options, suggesting a different, more dynamic choice context with competing reinforcers. Keanan discusses his work in this area, in addition to the importance of confirming self-report findings by using multimethod approaches, such as psychophysiology. Keanan Joyner is a doctoral student at Florida State University and a Ford Fellow.
