  1. Primary Task Distraction MAJ Shane Grass LCDR Eric McMullen Advisor: Dr. Ji Hyun Yang

  2. Basic Construct • People have a limited capacity to divide attention • At what point does divided attention affect performance of a primary task? • Officers conducting operational tasks such as driving a ship or flying an aircraft are often inundated with reports and relevant secondary tasks • Pertinent to primary task • Have the potential to distract, degrading primary task • Proposal: Investigation into distractions’ effects • May significantly hinder operator perform. • Give the military insight into effective task completion

  3. Basic Construct Inter-plane Following Distance
