Abstract A central debate in the cognitive sciences surrounds the nature of adult speakers’ linguistic representations: Are they purely syntactic (a traditional and widely held view; e.g., Branigan & Pickering, #cogs12697-bib-0006), or are they semantically structured? A recent study (Ambridge, Bidgood, Pine, Rowland, & Freudenthal, #cogs12697-bib-0003) found support for the latter view, showing that adults’ […]

Abstract Current understanding of the development of quantity representations is based primarily on performance in the number‐line task. We posit that the data from number‐line tasks reflect the observer’s underlying representation of quantity, together with the cognitive strategies and skills required to equate line length and quantity. Here, we specify a unified theory linking the […]

Abstract How do people pursue rewards in risky environments, where some outcomes should be avoided at all costs? We investigate how participant search for spatially correlated rewards in scenarios where one must avoid sampling rewards below a given threshold. This requires not only the balancing of exploration and exploitation, but also reasoning about how to […]
