Types of Errors...

• Slips:
  - correct plan but incorrect action;
  - more readily observed.
  
  
• Lapses:
  - correct plan but incorrect action;
  - failure of memory so more covert?
  
  
• Mistakes:
  - incorrect plan;
  - more complex, less understood.
  
  
• Human error modelling helps to:
  - analyse/distinguish error types.
