Paper accepted, Sohan Van Souza is going Dutch

I am proud to report that the paper I co-authored and submitted in February has been accepted for publication and presentation at the 2009 annual conference of the Cognitive Science Society. We turned in the final version recently, and it looks like I will be travelling to Amsterdam to present "Gal et al (2009)" with the first author at the conference in late July. I am excited to go to Europe after all the missed chances in years past. More excited am I that my first research paper submission was accepted, and that I have a publication to my credit.

Gal, Y., Dsouza, S., Pasquier, P., Rahwan, I. and Abdallah, S. (2009), The effects of goal revelation on computer-mediated negotiation, Proceedings of Cogsci 2009: 31st Annual Conference of the Cognitive Science Society

This paper studies a novel negotiation protocol in settings in which players need to exchange resources in order to achieve their own objective, but are uncertain about the objectives of other participants. The protocol allows participants to request each other to disclose their interests at given points in the negotiation. Revealing information about participants’ needs may facilitate agreement, but it also exposes their negotiation strategy to the exploitation of others. Empirical studies were conducted using computer-mediated negotiation scenarios that provided an analogue to the way goals and resources interact in the world. The scenarios varied in the individual positions and interests of participants, as well as the dependency relationships that hold between participants. Results show that those who choose to reveal their underlying goals outperform negotiators in the same setting that use a protocol that forbids revelation. In addition, goal revelation has a positive effect on the aggregate performance of negotiators, and on the likelihood to reach agreement. Further analysis show goal revelation to be a cooperation mechanism by which negotiators are able to identify acceptable agreements in scenarios characterized by few socially (Pareto) beneficial outcomes.


  1. That is so cool Sohan! Your topic and conclusions are interesting to me since a lot of games I play rely on such in game negotiations and trade.

  2. Amsterdam is a beautiful town, I hope you'll get some time to visit it !

  3. I will. After the conference, I plan to make the best use of my visa, and tour Amsterdam plus three or four other major cities in neighboring continental western Europe.
