We explore the links between agrobiodiversity and farm financial benefits in small-scale agroecosystems. We measured crop diversity in a subsistence-oriented agricultural production system: home gardens (n=250) in the Iberian Peninsula. We...

Many accounts of decision making and reinforcement learning posit the existence of two distinct systems that control choice: a fast, automatic system and a slow, deliberative system. Recent research formalizes this distinction by mapping these systems to "model-free" and "model-based" strategies in reinforcement learning. Model-free strategies are computationally cheap, but sometimes inaccurate...
