Huw Jarvis @huwjarvis.net · 27/04/2026Next, we ask: Why? What purpose might effort-sensitive learning rates serve? 🧐 Model simulations suggest that dopamine supports a mechanism that can 'rescue' learning performance in those individuals who are most averse to exerting effort in the first place. journals.plos.org/plosbiology/... 4/5 110
Huw Jarvis @huwjarvis.net · 27/04/2026We compared this to a separate group on sulpiride 800mg (n=23)🔴, a drug that blocks dopamine at post-synaptic D2 receptors. Critically, the effect of effort on learning was not seen on sulpiride. While learning rates were still asymmetrical in this group, they were not sensitive to effort! 3/5 100

Here, we show it also supports their interaction! w A Huynh, D Obawede, J Coxon @coxon.bsky.social, M Bellgrove, and T Chong @trevorchong.bsky.social #dopamine #learning #effort @plosbiology.org journals.plos.org/plosbiology/... 1/5 33011
