Kako virtualna stvarnost može transformirati znanost o ponašanju i poboljšati reproduktivnost

A groundbreaking initiative led by a global coalition of researchers aims to harness virtual reality (VR) to revolutionize behavioral science and tackle the long-standing issue of research reproducibility. In a newly published paper in the Proceedings of the National Academy of Sciences, 41 scientists from diverse fields and regions have proposed standardized protocols for conducting VR-based behavioral studies. Their work outlines a framework designed to bring consistency, transparency, and accessibility to a rapidly evolving domain. The researchers emphasize that VR offers a unique capacity to create controlled, immersive environments that can simulate real-world scenarios with high precision. This capability allows participants to engage in complex behaviors under tightly regulated conditions, which traditional methods often struggle to achieve. However, the group warns that enthusiasm for VR’s potential is growing faster than the establishment of rigorous scientific standards. Without uniformity in methodology, the field risks fragmentation, with each discipline developing its own isolated approaches. To address this challenge, the researchers introduced an interactive checklist accessible through the website www.vrprotocols.org. The tool provides guidelines for designing, executing, and reporting VR studies, ensuring alignment with best practices in open science. According to Anand P. A. van Zelderen, founder of the Openverse and assistant professor at SKEMA Business School, the lack of shared standards has hindered progress in VR research. He described the new protocols as providing a “common language” for researchers, peer reviewers, and journal editors to communicate effectively. The checklist focuses on three key areas: interoperability, procedural standardization, and data sharing. Interoperability ensures that VR studies are not confined to particular hardware or software platforms. By advocating for common engines, open standards, and clear licensing agreements, the protocols aim to facilitate the transfer of simulations between laboratories and allow for updates as technology evolves. Procedural standardization addresses inconsistencies in how studies are conducted, such as differences in participant instructions or measurement techniques. The protocols recommend using standardized metrics like “VR presence,” along with ethical, accessibility, and safety benchmarks. Data sharing extends beyond results, encouraging the distribution of code and virtual assets so that other researchers can reproduce and build upon existing studies. Timothy D. Hubbard, senior author of the paper and a professor at Dublin City University, highlighted the importance of these protocols in shaping the future of VR research. He expressed hope that the guidelines would serve as foundational principles for emerging scholars, helping to elevate the overall quality of research in the field. The Openverse, however, sees these protocols as more than a means of maintaining standards, they believe they could play a pivotal role in solving the reproducibility crisis that has plagued behavioral sciences over the past two decades. Reproducibility has become a central concern in psychology and related disciplines, with numerous studies failing to produce consistent results when replicated. VR, according to the researchers, presents a compelling alternative due to its inherent repeatability. Unlike conventional experimental setups, which can vary based on environmental factors or human error, VR environments can be precisely calibrated and replicated across different locations. For instance, studies have already been conducted aboard the International Space Station, demonstrating that participants experienced identical conditions regardless of geographical location. University of California, Merced, research scientist Theodore C. Masters-Waage explained that VR functions not only as a research method but also as a “portable laboratory.” Researchers can design every aspect of a participant’s experience with meticulous attention to detail, ensuring that variables are controlled and outcomes are reliable. This level of precision makes VR particularly valuable for investigating complex human behaviors in controlled settings. Van Zelderen emphasized that the publication marks the initial phase of the Openverse’s broader mission, to dismantle financial and technological barriers that limit access to VR research. He called for widespread adoption of the proposed protocols, believing that doing so will enable VR to flourish across the behavioral sciences. The group now seeks to encourage institutions, journals, and funding bodies to integrate these standards into their practices, fostering a more collaborative and transparent research ecosystem.
