Word Forms Reflect Trade‐Offs Between Speaker Effort and Robust Listener Recognition

Abstract How do cognitive pressures shape the lexicons of natural languages? Here, we reframe George Kingsley Zipf’s proposed “law of abbreviation” within a more general framework that relates it to cognitive pressures that affect speakers and listeners. In this new framework, speakers’ drive to reduce effort (Zipf’s proposal) is counteracted by the need for low-frequency […]

When the Ends Justify the Mean: The Endpoint Leverage Effect in Distribution Perception

Abstract Previous research described different cognitive processes on how individuals process distributional information. Based on these processes, the current research uncovered a novel phenomenon in distribution perception: the Endpoint Leverage Effect. Subjective endpoints influence distribution estimations not only locally around the endpoint but also influence estimations across the whole value range of the distribution. The […]

A Hierarchical Bayesian Model of Adaptive Teaching

Abstract How do teachers learn about what learners already know? How do learners aid teachers by providing them with information about their background knowledge and what they find confusing? We formalize this collaborative reasoning process using a hierarchical Bayesian model of pedagogy. We then evaluate this model in two online behavioral experiments (N = 312 […]
