    "abstract": "In real-life decision environments people learn from their direct\nexperience with alternative courses of action. Yet they\ncan accelerate their learning by using functional knowledge\nabout the features characterizing the alternatives. We designed\na novel contextual multi-armed bandit task where decision\nmakers chose repeatedly between multiple alternatives characterized\nby two informative features. We compared human\nbehavior in this contextual task with a classic multi-armed\nbandit task without feature information. Behavioral analysis\nshowed that participants in the contextual bandit task used the\nfeature information to direct their exploration of promising\nalternatives. Ex post, we tested participants’ acquired functional\nknowledge in one-shot multi-feature choice trilemmas.\nWe compared a novel function-learning-based reinforcement\nlearning model to a classic reinforcement learning. Although\nreinforcement learning models predicted behavior better in the\nlearning phase, the new models did better in predicting the\ntrilemma choices",
