Interdisciplinary Team Examines Brain Responses to Sacred Spaces
A new exploratory study led by researchers at The Catholic University of America investigates how sacred and secular architecture differentially affect believers through neurophenomenological methods. The work, titled "Cognitive-Aesthetic Effects of Sacred vs. Secular Architecture on Believers: A Neurophenomenological Exploratory Study," combines architecture, neuroscience, theology, and cognitive psychology to measure physiological and experiential responses in real-world settings.
The research team includes Julio Bermudez, Lin-Ching Chang, Mohamad Z. Koubeissi, Tom Beaudoin, Edward Trudeau, Amir Ebadi, Zakaria Djebbara, Madison Moore, Juliana Keagle, and Yoshio Nakamura. Their findings appear in a recent publication available at ScienceDirect.
Study Design and Methodology
Participants, all practicing Roman Catholics, visited two architecturally comparable sites in Washington, D.C.: the Basilica of the National Shrine of the Immaculate Conception and Union Station. Researchers equipped volunteers with mobile EEG headsets to track brainwave activity alongside devices measuring heart rate, blood pressure, and skin conductance. At designated stopping points, quantitative readings were paired with qualitative interviews capturing subjective experiences.
This neurophenomenological approach integrates first-person accounts with objective biometric data, allowing researchers to correlate reported spiritual sensations with measurable neural patterns. Preliminary analyses indicate heightened gamma wave activity and frontal lobe engagement in the sacred environment, suggesting focused attention and altered default mode network activity compared to the secular transit hub.
Preliminary Biometric Insights
Early data reveal that sacred spaces elicit distinct physiological signatures. Increased gamma oscillations across brain regions point to heightened integrative processing, while elevated frontal lobe activation correlates with intense concentration and reduced mind-wandering. These patterns differ markedly from responses recorded in secular spaces of similar scale and formality.
The study builds on prior Templeton Religion Trust-funded projects that established baseline differences in how believers perceive and inhabit sacred versus everyday environments. Ongoing analysis aims to isolate specific architectural features—such as scale, light, acoustics, and symbolic elements—that drive these effects.
Broader Implications for Design and Spirituality
Results carry significance for architects, religious institutions, and neuroscientists interested in the built environment's influence on cognition and well-being. If sacred architecture reliably facilitates spiritual states, designers may incorporate evidence-based elements into worship spaces to support contemplative practices.
Stakeholders in higher education, particularly those in architecture and theology programs, can draw on these methods to advance interdisciplinary curricula. The Catholic University of America's School of Architecture and Planning has hosted related symposia exploring these intersections.
Expert Perspectives and Institutional Context
Lead researcher Julio Bermudez, professor at The Catholic University of America, has long examined architecture's intersection with phenomenology and spirituality. Co-authors bring complementary expertise: neurologists contribute EEG interpretation, theologians frame experiential dimensions, and computer scientists assist with data classification.
Funding from the Templeton Religion Trust underscores growing interest in empirical approaches to religious experience. Similar initiatives at other universities explore biometric responses to built environments, expanding the evidence base for design decisions in sacred contexts.
Future Directions and Research Opportunities
The team continues refining machine-learning models to classify cognitive-aesthetic responses from biometric streams. Expanded studies may include diverse faith traditions and additional building types to test generalizability.
Academic job seekers and researchers in neuroscience, architecture, and religious studies may find opportunities in related grants or collaborative projects. Institutions seeking faculty with expertise in neurophenomenology or sacred space design are positioned to advance this emerging field.

Practical Applications for Religious Communities
Religious organizations evaluating renovations or new construction can reference these findings when prioritizing features that enhance spiritual engagement. Data-driven insights complement traditional aesthetic and symbolic considerations.
University administrators overseeing campus chapels or interfaith centers might apply analogous principles to create environments conducive to reflection across belief systems.
