Further emotional signals are communicated across a variety of channels verbally and nonverbally. These channels vary in capacity the specificity of the information effectively communicated and the cognitive overhead in using them. A person can smile at a cute baby without much thought but may need more resources to verbally express happiness. Agent teams typically have two channels communication and action. These differences suggest potential benefits for using emotions in pure agent teams. For instance there might be an advantage to having agent teams communicate attitudinal or emotional information as well as an advantage to exposing this information to teammates automatically through low-cost channels. Consider building agents so that they could not only communicate and act deliberately after an accurate and possibly computationally intensive assessment of the state but also emit some low-cost emotional signal based on an approximate state assessment. For example a robot could have hardwired circuitry that triggers light-emitting diodes that represent emotional cues like fear to indicate a state where the robot is in danger worry to indicate low likelihood of success and helplessness to indicate that it needs to help. These emotional cues can be computed and transmitted quickly and could result in the team being able to coordinate itself without having to wait for the accurate state estimation to be performed. If for example agents could use these emotional cues to determine action selection of the other agents in the team it could result in greater synchronization and consequently better teamwork. EXPERIMENTAL ILLUSTRATION In this section as an illustration of the effect of emotions on multiagent teamwork we demonstrate how the allocation of roles in a team is affected by emotions like fear. Our approach is to introduce an RMTDP Nair Tambe Marsella 2003 for the team .
