Paid REU positions available (2014.08.24)

Dr. Leen-Kiat Soh (Department of Computer Science and Engineering) and I are looking for undergraduate research assistants to help analyze data for a National Science Foundation funded project on predicting human decision making with machine learning. An NSF Research Experiences for Undergraduate (REU) supplement will pay a stipend to two undergraduates to help on this project in Fall 2014 and Spring 2015. This project involves both using decision trees to categorize an existing set of behavioral data and developing further experiments to collect and analyze more data. In addition to conducting research, the assistants are expected to meet weekly with Drs. Stevens and Soh to discuss the project. We are looking for students interested in cognitive science or the interface between computer science and human psychology. Experience in machine learning and programing is desired but not required. If interested in this position, please contact Dr. Stevens at

Join us at choice workshop in Berlin (2012.05.20)

Along with Michel Regenwetter at the University of Illinois at Urbana-Champaign, ADML is hosting the Workshop on Testing Theories of Choice from 18-20 July 2012 in Berlin, Germany. The goal of this workshop is to bring together scholars interested in intertemporal choice, risky choice, game theory, and methods for theory testing in the decision sciences. We have arranged for a number of invited speakers to discuss their research related to this goal. Make sure to register before 30 June!

ADML goes green! (2012.05.02)

ADML has received funding from the College of Arts and Sciences and the University of Nebraska-Lincoln to start studying environmental decision making, develop a seminar series, and assemble an interdisciplinary team of researchers interested in environmental cognition and education.

Behavioural Processes tribute to Alex Kacelnik is available (2012.01.29)

The journal Behavioural Processes has published a tribute to Alex Kacelnik with great articles from host of eminent comparative psychologists and behavioral ecologists. Don't forget to check out ADML's article on intertemporal choice in lemurs.

How long can lemurs wait? (2011.11.12)

The ADML has a paper coming out on intertemporal choice in lemurs. The paper is an invited article to a special issue of Behavioural Processes honoring the contributions of Alex Kacelnik. It shows lemurs to be about as impulsive as marmosets, and suggests that larger species of animals tend to be more patient than smaller species.

Phylogenetic comparative psychology is born (2011.10.19)

Dr. Stevens recently attended a NESCent working group on Phylogenetic Comparative Psychology (or PhyloPsy for short). This is a great group of folks (headed by Charlie Nunn and Brian Hare) interested in a truly comparative approach to cognition grounded in a strong knowledge of phylogenetics. There first concept paper was published in the journal Animal Cognition.
