Advanced Aviation Psychology: Human Information Processing

What the domain covers

This domain examines the information-processing chain: sensing, perception, decision-making, response and feedback. Candidates must understand the limits of each stage, the role of attention and working memory, and decision models such as the DECIDE model and recognition-primed decision-making.

Concepts to master

  • Sensory input: vision dominates in aviation; hearing is secondary; vestibular cues are unreliable in flight.
  • Perception and interpretation: expectation and experience shape interpretation; illusions arise here.
  • Decision-making: analytical (DECIDE: Detect, Estimate, Choose, Identify, Do, Evaluate) versus naturalistic (recognition-primed).
  • Response and feedback: motor response and confirmation; feedback loops correct errors.
  • Information overload: channel capacity limits; chunking and automation help but can add monitoring load.

Question traps

Questions often confuse the DECIDE model with the SHELL model; DECIDE is a decision tool, SHELL a systemic framework. Another trap is assuming decision-making is always conscious and analytical; recognition-primed decisions are fast and experience-based. Also remember that feedback is essential for correcting errors.

Worked example / rule of thumb

An experienced captain instantly recognises a go-around is needed on a short, wet runway. This is recognition-primed decision-making, not a DECIDE cycle. Rule of thumb: if the decision is fast and pattern-based, it is naturalistic; if it is stepwise and deliberate, it is analytical.
