Effects of effort training on effort-based impulsive choice

Because impulsive decision-making is correlated with many maladaptive tendencies, researchers have increasingly studied methods for reducing choice. These efforts primarily focused on increasing choices of larger, more-delayed rewards. A second type choice selecting a smaller, less-effortful reward over more-effortful one. Little nonhuman research has examined experimental effort-based Within the realm delay-based choice, extended exposure to reinforcer delays proven effective in rats. The current study took similar tack by evaluating if reductions could be achieved providing rats high-effort training, that is, reinforcement contingencies requiring large number responses. Male were randomly assigned either training (fixed-ratio 50) or low-effort 1) group. Following both groups completed test High-effort produced temporary reduction In same phase, also differed response run durations (shorter following training), larger differences initial sessions, which may contributed short-term effect
