Approach-Avoidance Bias in Virtual and Real-World Simulations: Insights from a Systematic Review of Experimental...

Area of Science:

• Psychology
• Cognitive Science
• Human-Computer Interaction

Background:

• Approach and avoidance bias (AAB) reflects automatic reactions to emotional stimuli.
• Traditional AAB studies often lack ecological validity.
• Investigating AAB in naturalistic contexts presents methodological challenges.

Purpose of the Study:

• To systematically review the use of virtual reality (VR) and real-world setups for studying AAB.
• To summarize methodological innovations and challenges in AAB research.
• To evaluate the alignment of experimental designs with research objectives.

Main Methods:

• Systematic review of peer-reviewed articles using VR and real-world setups for AAB research.
• Analysis of experimental designs, stimuli, response metrics, and technical aspects.
• Identification of limitations and methodological coherence.

Main Results:

• 14 studies were included, showing diverse methodologies and response metrics.
• Variability in VR technology application and participant interaction paradigms was observed.
• Discrepancies between simulated and natural actions were noted; few studies included control conditions or physiological data.

Conclusions:

• VR provides a promising ecologically valid setup for studying AAB with dynamic interactions.
• A coherent framework for VR-based AAB research is essential for advancing the field.
• Addressing foundational challenges in VR design will lead to more reliable paradigms and effective interventions for bias modification.
