Since Reynolds's first model of a decentralised flocking system [Reynolds, 1987] there have been many incremental developments aimed at enhancing the realism of simulated autonomous agent behaviour. Multi-agent systems have been developed to investigate the consequences of predation on a flocking system. Much of the research in this area, however, focuses on specific aspects of predator-flock interactions and there has been little consolidation between projects.
   This project integrates two such developments and investigates whether a full cycle of predation behaviour [Nishimura, 2000 2001] [Feder, 1986] can be combined with the simulation of agent emotional responses [Delgado-Mata, 2003] and still give rise to simulated agent behaviour that ties in with our perceptions of reality.
   Analysis against the findings from the original research and the observations made directly in the field of predation [Purves 2001] [Curio 1976] show that not only can the work of Reynolds, Nishimura and Delgado-Mata coexist in harmony, but their consolidation actually serves to increase the reality of the predator-prey simulation's emergent behaviour.
