Stimulus-response compatibility with wheel-rotation responses: will an incompatible response coding be used when a...

Area of Science:

• Human-Computer Interaction
• Cognitive Psychology
• Motor Control

Background:

• Understanding stimulus-response compatibility is crucial for designing intuitive interfaces.
• Previous research has explored frame of reference effects in human-computer interaction.
• The influence of explicit instructions on response coding remains an area for investigation.

Purpose of the Study:

• To investigate how different frames of reference (hand-referenced vs. cursor-referenced) influence stimulus-response compatibility in a steering wheel task.
• To determine the impact of instructional emphasis (hand movement vs. wheel/cursor movement) on response coding.
• To examine whether compatible mappings are prioritized over frame of reference adherence.

Main Methods:

• Three experiments were conducted using a steering wheel task with left-right tone stimuli.
• Participants used one of two stimulus-response assignments.
• Instructions varied to emphasize either hand movements, wheel movements, or a cursor controlled by the wheel.

Main Results:

• In Experiment 1 (no emphasis), responses were coded based on the frame yielding a compatible mapping.
• In Experiment 2 (hand emphasis), responses were coded relative to the hand-referenced frame.
• In Experiment 3 (cursor emphasis), responses were coded relative to the cursor-referenced frame, even with incompatible mappings.

Conclusions:

• Instructional context significantly influences the frame of reference used for coding responses.
• The dominant frame of reference can override the principle of stimulus-response compatibility.
• These findings have implications for designing user interfaces that leverage contextual cues for optimal performance.
