Gillian Weeks
Gillian Weeks is a junior Psychology major and a member of the Reasoning and Decision Making Lab. She conducts research on the left digit effect in complex judgment and is particularly interested in clinical applications of cognitive psychology.
Katherine Williams, formerly a joint lab coordinator at Wesleyan University, is now a graduate student in Developmental Psychology at the University of Texas at Austin. She is broadly interested in how social, linguistic, and cognitive factors interact to support learning.
Hilary Barth
Hilary Barth is a professor in the Department of Psychology at Wesleyan University and director of the Cognitive Development Lab at Wesleyan. Research in her lab investigates mathematical cognition; thinking and learning about number, space, time, and probability; social cognition; and decision making.

Andrea L. Patalano is a professor in the Department of Psychology and the Program in Neuroscience and Behavior at Wesleyan University, where she runs the Reasoning and Decision Making Lab. Her research interests include number-related judgment biases, indecisiveness and decisional delay, and neural underpinnings of decision making. Â
Abstract: The left digit effect (LDE), a numerical bias in which the left-most digit of a number disproportionally affects one’s perception of magnitude, has been observed across diverse contexts. Adults completed a multi-attribute judgment task in which they rated hypothetical applicants for college admission, and a self-paced number line estimation task. A small LDE was found in the judgment task and a large effect in number line estimation. There was no correlation between participants’ LDEs across tasks. These findings provide evidence that the LDE, while smaller, extends to multi-attribute judgment, but performance cannot be predicted from a number skills task.
