Weatherly, Jeffrey N.; Derenne, Adam – Learning and Motivation, 2013
The present study tested whether participants would discount "won" money differently than they would "owed" money in a probability-discounting task. Participants discounted $1000 or $100,000 that they had won in a sweepstakes or that was owed to them using the multiple-choice (Experiment 1) or fill-in-the-blank (Experiment 2) method of collecting…

Weatherly, Jeffrey N.; Huls, Amber – Learning and Motivation, 2008
Studies have demonstrated that rats will increase their operant rate of response for a low-valued reinforcer if a high-valued reinforcer will be available later in the session. Research on this positive induction effect suggests that at least three factors account for its appearance: premature responding for the yet unavailable high-valued…

Weatherly, Jeffrey N.; Nurnberger, Jeri T.; Austin, David P.; Wright, Carol L. – Learning and Motivation, 2006
Research has suggested that rats increase their response rate for a low-valued reinforcer when a high-valued reinforcer will soon be available (i.e., positive induction) because the value of the low-valued substance has increased. The present study tested if such a procedure could be used to increase rats' responding for a non-reinforcing food.…

Weatherly, Jeffrey N.; Arthur, Emily I. L.; Palbicki, Janel; Nurnberger, Jeri T. – Learning and Motivation, 2004
Research has demonstrated that rats' rates of operant behavior maintained by 1% sucrose reinforcement in the first half of an experimental session are heightened when food-pellet reinforcers, rather than 1% sucrose, will be available in the second half. Experiment 1 showed that rats that had been displaying this positive induction effect acquired…
