Performance Constrained by Cognitive Limitations

• Memory
• Logical reasoning abilities
• Illusions
• Perceptual
• Cognitive
• Coordinate transformation
• Ability to predict and anticipate states and
  actions
• Information fusion
• Decision combining utilities, uncertainties
• Abstract sources
• Attentional limitations

Traditional Solutions

• Traditional Solutions
• Cognitive aids
• Checklists
• Mnemonic aids (Coffee cup)
• Alerts
• Training and rote learning
• Divide and conquer Team of operators/agents
• Augmented Cognition
• Model the cognitive limitation
• Develop systems to amplify the ability

4
Principled Approach to Cognitive Amplification

• Identify limitations
• Quantify Model the limitations
• Develop amplifying principles
• Information compression
• re-mapping- visualization
• Information fusion
• Memory/context enhancemet
• Measure amplification
• Develop amplifying technology
