Generalizing perception-action coupling depends on context: Spatial updating is nonobligatory in virtual but not...

Area of Science:

• Cognitive Psychology
• Human-Computer Interaction
• Neuroscience

Background:

• Perception-action coupling, essential for environmental interaction, becomes automatic and obligatory with practice.
• Spatial updating, revising object relationships during locomotion, is typically obligatory in physical environments.
• Understanding how learned couplings generalize across contexts is crucial for virtual and mixed-reality applications.

Purpose of the Study:

• To investigate whether spatial updating remains obligatory in immersive virtual and mixed-reality environments.
• To examine the influence of context similarity on the generalization of obligatory perception-action coupling.
• To determine if sensorimotor alignment effects persist across different environmental realities.

Main Methods:

• Participants learned object arrays in virtual, mixed, or physical environments.
• Judgments of relative direction were performed from imagined and actual headings.
• Spatial updating was assessed via pointing accuracy, measuring the aligned-imagined effect.

Main Results:

• Spatial updating remained obligatory in mixed-reality (Experiments 3-4) and physical environments (Experiment 5).
• Obligatory spatial updating was not observed in immersive virtual environments (Experiments 1-2).
• Sensorimotor alignment effects were present when environments were similar but diminished in purely virtual settings.

Conclusions:

• Spatial updating is not obligatory in immersive virtual environments.
• Obligatory coupling generalizes to mixed-reality and physical environments but is context-dependent.
• The obligatory nature of learned perception-action couplings may decrease in less similar transfer contexts.
