Stimulus-response compatibility with pure and mixed mappings in a flight task environment

Area of Science:

• Human-Computer Interaction
• Cognitive Psychology
• Aviation Psychology

Background:

• The stimulus-response compatibility (SRC) effect influences performance in human-machine interfaces.
• Understanding SRC is crucial for designing effective aviation cockpits.
• Previous research has explored SRC in various contexts, but less in complex simulated flight environments.

Purpose of the Study:

• To investigate the stimulus-response compatibility (SRC) effect in a simulated flight environment.
• To determine how different display formats (inside-out, outside-in) and response types (yoke turns, button presses) affect SRC.
• To analyze sequential effects influencing SRC in flight tasks.

Main Methods:

• Four experiments were conducted using simulated flight tasks.
• Experiments 1 and 2 utilized pure and mixed mappings with inside-out and outside-in attitude displays.
• Experiments 3 and 4 employed a simplified display and task, differentiating between yoke turns and button presses as responses.

Main Results:

• The SRC effect was observed with mixed mappings when responses involved flight yoke turns (Experiments 1-3).
• Conversely, the SRC effect was absent with mixed mappings when responses were button presses (Experiment 4).
• Sequential effect analyses indicated that reduced SRC in Experiments 1-3 was partly due to repeated congruent trials, but this did not explain the elimination in Experiment 4.

Conclusions:

• The type of response significantly modulates the SRC effect in simulated flight.
• Button press responses may eliminate the SRC effect, unlike yoke turns, suggesting different cognitive processing.
• Findings have direct implications for optimizing aviation cockpit design and interface usability.
