Videos now available for the recent Conference Workshop on Exploration-Exploitation Trade-Offs, hosted by the Cognitive Science Society and sponsored by the Jacobs Foundation.

To view the videos, visit the Workshop Google site, which will retain active video links for the rest of the year. These videos are also shared on Databrary, and will stay accessible there permanently.

About the Workshop:
All cognitive systems both gather information and use that information to make decisions (e.g., explore and exploit). But there is an intrinsic tension between these two aspects of cognition. Exploration is costly in that resources allocated to information-seeking are unavailable for action. Moreover, actions have to be taken before all relevant information is available. When should a cognitive system seek new information and when should it stop to decide how to act? How do people and other organisms resolve this tension between exploration and exploitation? Is there an optimal way of doing so? And how can systems be motivated to seek information when that pursuit is costly and the immediate utility of the information may not be apparent?
