Sara Levens, Ph.D. currently has be given a Courtesy Post-Doctoral appointment. Sara completed her Ph.D. in Psychology from New York University in New York City. She also holds a BA in Psychology from the University of California at Berkeley. Her past research has focused on emotions and decision making, neuroeconomics, emotional experiences and altruistic behavior. Young-Suk received his Bachelor's in Computer Science and Engineering from in 1997. He is currently pursuing his Master's in Software Engineering at Carnegie Mellon. Young-Suk has eleven years of IT consulting experience for Panamanian and Koreans organizations in such fields as telecommunication, finance, transportation, and government. He is also the founder and director of , a culture network for Panama.
Models that assume reliance on small samples of past experiences have
a large advantage over models that assume reliance on running averages
of the previous payoffs (like traditional reinforcement learning and
fictitious play models).
The difference between learning in market entry games, and learning
in individual choice tasks is not large. Indeed, the best models in
the current competition can be described as refinements of the best
models i n our previous competition that focused in individual repeated
choice task (see Erev et al., 2010).
The Dynamic Decision Making Laboratory is also proud to announce the . The tool is our lab's effort to formalize the theoretical approach to modeling, and to make the Instance-Based Learning Theory shareable, generalizable, understandable, robust, communicable, and usable. The IBLTool provides a GUI framework to make your own cognitive models based in Instance-Based Learning Theory without needing to program and will interface with tasks written in any number of programming languages through socket protocols. The tool is currently available for . We would like to extend hearty thanks to both Ripta Pasay and Varun Dutt for their tremendous work done on the IBLTool. The IBLTool was also demonstrated at a tutorial to graduate students in Psychology and Mathematics at the . We would like to thank all those that attended and made it a success. In the past year, the lab has been pursuing exciting and interesting new research directions with fMRI. In preparation of this, members of the lab pursued continuing education and engaged with possible new collaborators. At the beginning of the year, Hau-yu took a week-long course on fMRI data analysis with SPM8. Coty also recently attended the . Last month, Coty was invited to give a talk on the emerging field of decision neuroscience at the Interdisciplinary Symposium on Decision Neuroscience held at Temple University's Fox School of Business. Some of our preliminary findings for a recent fMRI project were also presented at the symposium by our collaborator in the project, from . This project investigates trust in behavior as a function of eliciting theory of mind processing when playing the Trust Game opposite human and computer players. The lab also collaborated with , also in the SDS department, to submit a grant proposal to the Army Research Institute to investigate an fMRI extension of our research on the socio-emotional factors of cooperative behavior. The other big project we are moving forward with is . In June, we headed a data collection effort with middle school/high school students in Israel using the PeaceMaker game. We are excited to have been afforded the opportunity to collect data from participants that live within the region of influence demonstrated in the PeaceMaker game to see how their personal experience with the conflict affects resolution in the game. As part of our bottom-up investigation of cooperative behavior, our lab developed new multiplayer initiatives of the classic Prisoner's Dilemma and Chicken game from game theory dubbed the "2x2 games." A collaborator, Ion Juvina, has additionally developed the Iterated Prisoner's Dilemma (IPD2) paradigm to capture the dynamics of power between groups of competing and cooperating individuals. The IPD2 features two levels of competition and cooperation both within and between groups of individuals. Our efforts with the 2x2 and IPD2 games also extends to computational modeling based on the Instance-Based Learning Theory. Our hope is to augment our cognitive theory of learning and performance with important factors of personality and social interaction.
