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.

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.

Three Line Scene

Story Knowledge

If agentx is confident enough about his character And if agenty is not confident about agentx character Then agentx perform an action that is highly representative of agentx character

logical representations of SMM negotiation

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.
