Probabilistic reward task
WebbRecently, we described a probabilistic reward task based on a differential reinforcement schedule that allowed us to objectively assess participants’ propensity to modulate behavior as a function of reward (Pizzagalli et al., 2005a). In this task, participants are confronted with a choice between two responses that are linked to different Webb5 aug. 2024 · Delay discounting and probability discounting decision making tasks in rodent models have high translational potential. However, it is unclear whether the discounted value of the large reward option is the main contributor to variability in animals' choices in either task, which may limit translation to humans.
