Alongside the mainstream of our research work on social intelligence in robots, we also investigate computational models of human social cognition, which we successfully compare to data from humans. There are three principal areas in which we work:
- Modeling social comparison processes and their role in group cohesion. We have developed an algorithmic model of Festinger’s Social Comparison Theory, and used it to simulate human group behavior:

- We used qualitative reasoning (QR) to model crowd-level behavior and evolutions of demonstrations, successfully predicting what demonstrations will turn violent.

- Most recently, we have begun to explore modeling the human mirror-neuron system at a process level. The mirror-neuron system is tied to human ability to infer the intent of others (indeed, even detect that motion is intentional), understand their actions, and interact with them. We are working on a novel plan recognition approach called mirroring (see also our plan-recognition research) which allows agents to understand others in terms of their own knowledge:
