Dopamine is implicated in effort & reward #learning, but how do these interact? @huwjarvis.net @trevorchong.bsky.social &co show that #dopamine supports the relationship between effort & learning, revealing how we learn from the consequences of our actions @plosbiology.org 🧪 plos.io/41FqSdX

Reward-based learning paradigm with effort manipulation. Top: Participants made a series of choices between two abstract stimuli by applying physical force to a pair of hand-held dynamometers. One stimulus required a negligible amount of force to select (low effort stimulus; >5% MVC) and the other a greater amount of force (high effort stimulus; >44% MVC). Participants, therefore, had to balance an aversion to the high effort stimulus against their desire to maximize reward. Bottom: Stimulus-reward contingencies across a single block of 150 trials. The probability of reward upon selecting a given stimulus was either P = 0.7 or P = 0.3. These contingencies reversed every 12 or 24 trials, and reversals were not signaled to participants.
