  1. Startle Response Changes Collective Behavior Tony Sang, Concordia College Dr. Derek A. Paley, UMD

  2. Collective Behavior • Autonomous agents within a group • Obey simple interaction rules • Lead to coherent group formation

  3. Collective Behavior • Black Jack Mackerel Bait Ball • StarlingMurmuration -http://www.wired.com/wiredscience/2013/03/powers-of-swarms/2/ -http://www.visitsomerset.co.uk/explore-somerset/countryside/starling-murmurations

  4. ModelUsed • Levine and Rappel’s spatial Dynamics • U is an interaction potential that decays exponentially -Herbert Levine and Wouter-Jan Rappel,Phys. Rev. E, VOLUME 63, 017101 (2000)

  5. Formations from Model

  6. Startle Response • Spatial dynamic models are incomplete • Startle/Fright Response -Large Change in Speed and Direction -Only for one time step • Model propagates startle probabilistically

  7. Coupling with Startle

  8. Questions Examined • How does Startle Response Change Formation? • Does the propagation of the stimulus change?
