For decades, scientists have used simple reinforcement learning models to explain this—basically, your brain keeps a running score and updates it with each new experience. But a fascinating new study suggests that picture is way too simple. Researchers built hybrid models combining neural networks with traditional cognitive frameworks to study how humans actually learn from rewards. Using a large dataset of human behavior, they discovered something striking: our brains…
