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...

Because of its potential role in providing ecosystem services and private benefits (food security), the concern about the loss of agrobiodiversity has grown. 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...
