Improv acting: A creative group performance where human actors, guided only by sets of game rules, co-construct stories on stage in real- time based on how they perceive the environment.

CoCoA Architecture This work This work focuses on focuses on these two these two components components Co-creative Cognitive Architecture (CoCoA)

A shared mental model is a cognitive construct maintained through the process of reaching cognitive convergence (i.e. to be on the same page) that incorporates the development of mutual beliefs between the improvisers’ mental models until a common mental model is reached.

Story Knowledge

logical representations of SMM negotiation If agent x is confident enough about his character And if agent y is not confident about agent x character Then agent x perform an action that is highly representative of agent x character

Evaluation - SMM was ablated for two improv agents leading to total consensus found approximately once in over 1500 lines. - SMM was then enabled for the improv agents. The agents reached cognitive convergence 4.5 times more often.
